The first start memory number is displayed on the first special figure memory display 48. The start right for starting the second special figure variation display game is stored as the second start memory (special figure 2 start memory) within a predetermined upper limit number (for example, 4). The second start memory number is displayed on the second special figure memory display 49.

  When the first special figure variation display game can be started (the first start memory number and the second start memory number are 0) and the game ball wins the first start winning opening 45, the start right is generated. The random number extracted with is stored as the first start memory, the first start memory number is incremented by 1, and the first special figure variation display game is immediately started based on the first start memory, At this time, 1 is subtracted from the first start memory number.

  In addition, since the second special figure fluctuation display game is executed in preference to the first special figure fluctuation display game, even if the first start memory number is not zero, if the second start memory number is zero, When the game ball wins the normal variation winning device 36 that forms the second start winning opening, the random number extracted with the start right is stored as the second start memory, and the second start memory number is incremented by one. At the same time, the second special figure variation display game is started based on the second start memory immediately after the execution of the first special figure variation display game being executed, and at this time, the second start memory number is decremented by one.

  On the other hand, a state in which the first special figure fluctuation display game or the second special figure fluctuation display game cannot be started immediately, for example, the first special figure fluctuation display game or the second special figure fluctuation display game has already been performed, and the special figure fluctuation display. If a game ball is won in the first start winning opening 45 when the game is not finished or in a special game state, if the first start memory number is less than the upper limit number (for example, less than four) The first start memory number is incremented by 1, and one random number extracted at the timing when the game ball is won in the first start winning opening 45 is stored as the first start memory.

  Similarly, in this case, when a game ball wins the normal variation winning device 36 that forms the second starting winning opening, if the second starting stored number is less than the upper limit number (for example, less than four), the second starting stored number is 1 is added, and one random number extracted at the timing when the game ball wins the second start winning opening is stored as the second start storage.

  When the first special figure fluctuation display game or the second special figure fluctuation display game is ready to start, the first special figure fluctuation display game or the second special figure fluctuation display is based on the first start memory or the second start memory. The game starts. At this time, the first special figure fluctuation display game and the second special figure fluctuation display game are not executed simultaneously, and the second special figure fluctuation display game is executed with priority over the first special figure fluctuation display game. It is like that.

  That is, when there is a first start memory and a second start memory, the second special figure variation display game is executed.

  The first special figure change display game and the second special figure change display game as the auxiliary game are executed by the first special figure display 38 and the second special figure display 39 provided on the game board 10. After a plurality of pieces of identification information are variably displayed, a predetermined result mode is stopped and displayed. In addition, a special figure fluctuation display game is executed in which a plurality of types of identification information (for example, numbers, symbols, character designs, etc.) are variably displayed on the display device 53 corresponding to each special figure fluctuation display game. And as a result of this special figure fluctuation display game, when the display mode of the first special figure display 38 or the second special figure display 39 becomes a special result mode, it becomes a big hit and a special game state (so-called , Jackpot state). Correspondingly, the display mode of the display device 53 is also a special result mode (for example, any one of the numbers in the flat order such as “7, 7, 7”). The game machine may not be provided with the first special figure display 38 and the second special figure display 39, and the special figure variation display game may be executed only by the display device 53.

  In addition, the gaming machine 1 of the present embodiment can generate a probability variation state (second probability state) as a gaming state based on the result mode of the special figure variation display game. This probability variation state (second probability state) is a state in which the probability of a hit result in the special figure variation display game is higher than the normal probability state (first probability state). It should be noted that the first special figure fluctuation display game and the second special figure fluctuation regardless of whether the first special figure fluctuation display game or the second special figure fluctuation display game results in the result mode of the special figure fluctuation display game. Both display games are in a probable state. Further, the probability variation state and the above-described short-time operation state can be generated independently, and both can be generated simultaneously, or only one can be generated.

  The effect control device 550 includes a CPU 551, a control ROM 552, a RAM 553, an image ROM 554, a sound ROM 555, a VDP 556, a sound LSI 557, an input / output I / F 558, a power-on detection circuit 559, a master IC 570, and an adder 590.

  The CPU 551 is connected to the game control device 500, receives a command signal from the game control device 500 as an interrupt signal (INT), and is a main control device that controls various effects based on the input command signal. The CPU 551 receives an interrupt signal from a controller 574 (described later) of the master IC 570 and an interrupt signal from the VDP 556.

  When an interrupt signal is input to the CPU 551, the CPU 551 interrupts the process currently being executed and executes a process corresponding to the input interrupt signal.

  The control ROM 552 stores invariant information (program, data, etc.) for effect control. The RAM 553 is used as a work area during production control.

  The image ROM 554 stores image data to be displayed on the display device 53, and the image ROM 554 is connected to the VDP 556. The sound ROM 555 stores sound data output from the speaker 30, and the sound ROM 555 is connected to the sound LSI 557.

  The VDP 556 is a processor that controls image output to the display device 53. The sound LSI 557 is a circuit that controls the sound output from the speaker 30.

  Note that the VDP 556 includes synchronization signal generation means for generating a synchronization signal that is synchronized with a cycle (1/60 second cycle) of updating an image displayed on the display device 53. Every time the synchronization signal is generated, the synchronization signal generation means inputs the generated synchronization signal to the CPU 551 as an interrupt signal.

  The input / output I / F 558 is an interface connected to the effect button 17.

  The effect button 17 is provided on the upper edge portion of the upper plate 21 and is operated by the player in an effect in the first special figure fluctuation display game or the second special figure fluctuation display game executed on the display device 53. .

  The CPU 551, VDP 556, RAM 553, control ROM 552, sound LSI 557, and input / output I / F 558 are connected via a bus 563.

  The power-on detection circuit 559 outputs a reset signal that initializes a register (not shown) of the master IC 570 to a default state (all 0s) via the adder 590 when the effect control device 550 is powered on.

  The CPU 551 outputs a reset signal to the input / output I / F 558 via the bus 563 when a predetermined condition is satisfied, and the input / output I / F 558 outputs the input reset signal to the adder 590.

  In any case, since the reset signal is input to the master IC 570 via the adder 590, if the reset signal is output from at least one of the power-on detection circuit 559 and the CPU 551, the reset signal is input to the master IC 570. The

  Next, the master IC 570 will be described.

  Master IC 570 designates the address of decoration control device 610 of the rendering device to be controlled, and outputs the control content of the rendering device to decoration control device 610 at the designated address.

  The master IC 570 is connected to the relay board (decoration control device) 600 through five connection lines of the connection line Vcc, the connection line Vact, the connection line SDA, the connection line SCL, and the connection line GND (see FIG. 5). The

  The connection line Vcc is a connection line for supplying power to the relay board 600 and the decoration control device 610. The connection line Vact is a connection line for supplying power to the effect device. The connection line SDA is a connection line for communicating data between the effect control device 550 and the decoration control device 610, and functions as a data line in the present embodiment. The connection line SCL is a connection line for inputting and outputting a clock signal used for data communication through the connection line SDA, and functions as a timing signal line in the present embodiment. The connection line GND shown in FIG. 5 is the ground of the power supplied by the connection line Vcc and the connection line Vact.

  The relay board 600 and the decoration control device 610 are connected to each other through the connection line Vcc, the connection line Vact, the connection line SDA, the connection line SCL, and the connection line GND, similarly to the master IC 570 and the relay board 600. The

  The master IC 570 and the decoration control device 610 perform two-line bidirectional communication using the connection line SDA and the connection SCL.

  When transmitting data to the relay board 600 and the decoration control device 610, the master IC 570 first changes the signal level of the connection line SDA from HIGH to LOW while maintaining the signal level of the connection line SCL at HIGH. Thus, a start condition for starting data output to the decoration control device 610 is established (a start condition is issued to the decoration control device 610).

  Thereafter, the master IC 570 changes the signal level of the connection line SCL to LOW, sets the signal level of the connection line SDA to the level of the first bit of the transmission data while the signal level of the connection line SCL is LOW, After a predetermined time, the signal level of the connection line SCL is changed from LOW to HIGH. When the signal level of the connection line SCL changes to HIGH, the decoration control device 610 takes in the signal level of the connection line SDA and recognizes it as the first bit of the transmission data. Next, the master IC 570 returns the signal level of the connection line SCL from HIGH to LOW.

  When this procedure is executed once, 1-bit data is transmitted from the master IC 570 to the decoration control device 610. Finally, this procedure is repeated eight times, so that all eight bits of transmission data are controlled from the master IC 570. It is transmitted to the device 610 (1 byte of data is transmitted).

  The master IC 570 releases the connection line SDA and returns the response signal from the decoration control device 610 when the signal level of the connection line SCL is returned from HIGH to LOW after the transmission of the last 8-bit data. It will be in the reception waiting state which waits to receive.

  In the reception standby state, the decoration control device 610 returns a 1-bit response signal (ACK or NACK described later) to the master IC 570 via the connection line SDA. Next, when the master IC 570 changes the signal level of the connection line SCL from LOW to HIGH to capture the level of the response signal, and after a predetermined time, changes the signal level of the connection line SCL from HIGH to LOW, the decoration control device 610 Release the connection line SDA.

  The master IC 570 alternately repeats the data transmission for 1 byte and the reception of the response signal for 1 bit, and continues until all the data to be output to the decoration control device 610 is output. When the output of the data to be output is completed, the master IC 570 changes the signal level of the connection line SDA from LOW to HIGH while maintaining the signal level of the connection line SCL at HIGH, thereby controlling the decoration control device 610. A stop condition for ending the data output to is established (a stop condition is issued to the decoration control device 610).

  The input BUF 571 is a storage device that temporarily stores data input from the decoration control device 610 via the connection line SDA.

  Specifically, when the master IC 570 is set to the input mode, the data transmitted from the decoration control device 610 to the master IC 570 is temporarily stored in the input BUF 571 with noise removed by the filter 575A.

  The output BUF 572 temporarily stores data to be output to the decoration control device 610 via the connection line SDA.

  The reset REG 573 is connected to the bus 563 and receives a command from the CPU 551 and outputs a reset signal to the controller 574. The controller 574 comprehensively controls the master IC 570 and executes various processes.

  The filter 575A removes noise from data input from the connection line SDA. When the driver 576A outputs data from the connection line SDA, the driver 576A applies a voltage at which the transistor 578A can operate to the transistor 578A.

  As shown in FIG. 9, a predetermined voltage is applied to the connection line SDA by the pull-up resistor R, and the connection line SDA is connected to the filter 575A and the transistor 578A.

  The transistor 578A uses a field effect transistor (FET) to reduce power consumption. The gate of the transistor 578A is connected to the driver 576A, and the drain is a connection line SDA to which a predetermined voltage is applied by the pull-up resistor R. And the source is grounded.

  If the voltage applied to the gate of the transistor 578A is smaller than a predetermined value for operating the transistor 578A, no current flows between the drain and the source, so that the voltage applied to the connection line SDA does not drop, and as a result The connection line SDA becomes HIGH level. On the other hand, if the voltage applied to the gate of the transistor 578A is equal to or higher than a predetermined value for operating the transistor 578A, a current flows from the drain to which the voltage of the predetermined value is applied to the grounded source. As a result, the connection line SDA becomes LOW level.

Note that the transistor 578A has a specification that does not break even when a current of about 10 milliamperes flows from the drain to the source. For this reason, it is possible to flow a current of about 10 milliamperes, which is much larger than the current value used when using a normal I ² C bus, to the connection line SDA, and the effect control device 550 and the decoration control device 610 The data transmission between them is configured to withstand failures due to noise.

  When the driver 576A outputs data from the connection line SDA, the driver 576A applies a voltage of a value that allows the transistor 578A to operate to the gate of the transistor 578A in order to pass a current between the drain and source of the transistor 578A. Then, the driver 576A outputs data from the connection line SDA by setting the voltage of the connection line SDA to HIGH level or LOW level.

  The filter 575B removes noise from data input from the connection line SCL. When the driver 576B outputs data from the connection line SCL, the driver 576B applies a voltage with which the transistor 578B can operate to the transistor 578B.

  As shown in FIG. 9, a predetermined voltage is applied to the connection line SCL by the pull-up resistor R, and the connection line SDA is connected to the filter 575B and the transistor 578B.

  The transistor 578B uses a field effect transistor (FET) to suppress power consumption, the gate of the transistor 578B is connected to the driver 576B, and the drain is a connection line SCL to which a predetermined voltage is applied by the pull-up resistor R. And the source is grounded.

  If the voltage applied to the gate of the transistor 578B is smaller than a predetermined value for operating the transistor 578B, no current flows between the drain and the source, so that the voltage applied to the connection line SCL does not drop, and as a result The connection line SCL becomes HIGH level. On the other hand, when the voltage applied to the gate of the transistor 578B is equal to or higher than a predetermined value for operating the transistor 578B, a current flows from the drain to which the predetermined voltage is applied to the grounded source, whereby the connection line SCL As a result, the connection line SCL becomes the LOW level.

Note that the transistor 578B has a specification that does not break even when a current of about 10 milliamperes flows from the drain to the source. Therefore, a current of about 10 milliamperes, which is much larger than the current value used when using the normal I ² C bus, can be passed through the connection line SCL, and between the effect control device 550 and the decoration control device 610. The data transmission is configured to withstand failures due to noise.

  When the driver 576B outputs a clock signal from the connection line SCL, the driver 576B applies a voltage with a value that allows the transistor 578B to operate to the gate of the transistor 578B in order to cause a current to flow between the drain and the source of the transistor 578B. Then, the driver 578B outputs a clock signal from the connection line SCL by repeatedly changing the voltage of the connection line SCL between a HIGH level and a LOW level.

  The power-on reset circuit 577 is used to set storage areas such as the input BUF 571 and the output BUF 572 to a default state when the master IC 570 is powered on and the voltage in the power-on reset circuit 577 reaches a predetermined value. Is output to the controller 574.

  Next, the relay board 600 and the decoration control device 610 will be described.

  The relay board 600 is directly connected to the master IC 570 in the decoration control device 610, that is, located on the most upstream side.

The decoration device 620 is a light-emitting device that is controlled by an I ² CI / O expander 615 (described later in FIG. 6) provided in the decoration control device 610 and flashes light when an electric current is passed. Etc. The accessory driving solenoid (SOL) 560 is a device that reciprocates when an electric current flows. The accessory driving solenoid (SOL) 560 moves an accessory for decoration (not shown) arranged on the game board 10 to produce an effect. The accessory driving motor (MOT) 561 is a device that rotates when an electric current flows, and produces an effect by moving the movable accessory 60. The accessory driving solenoid (SOL) 560 and the accessory driving motor (MOT) 561 are also controlled by the I ² CI / O expander 615 provided in the decoration control device 610.

  Note that the accessory driving SOL 560 may move the movable accessory 60, or the accessory driving MOT 561 may move an accessory not shown.

  The connection method between the effect control device 550 and the relay board 600 and the connection method between the relay board 600 and the decoration control device 610 other than the relay board 600 will be described in detail with reference to FIG. Details of the decoration control device 610 will be described with reference to FIGS.

  FIG. 5 is an explanatory diagram of connection of the decoration control devices 610A to 610F according to the embodiment of this invention. In addition, for convenience of explanation, one relay board 600 and six decoration control devices 610A to 610F are illustrated as the decoration control device 610, but actually, it is necessary to correspond to the specifications of the gaming machine. A large number of decoration control devices 610 are connected.

  The effect control device 550 is connected to the effect control device 550 via the connection line Vcc, the connection line Vact, the connection line SDA, the connection line SCL, and the connection line GND (hereinafter, these five connection lines are referred to as one harness). Is done.

  Two decoration control devices 610A and 610D are connected to the relay board 600 in parallel by harnesses.

  The decoration control device 610B is connected to the decoration control device 610A via a harness, and the decoration control device 610C is connected to the decoration control device 610B via a harness.

  On the other hand, a decoration control device 610E is connected to the decoration control device 610D via a harness, and a decoration control device 610F is connected to the decoration control device 610E via a harness.

  Each decoration control device 610 includes a connector serving as an attachment port for connecting the harness to itself. Since this connector is common to each decoration control device 610, it is possible to prevent erroneous wiring in the connection order of the connection lines.

Here, a method of controlling the decoration device 620 by the I ² CI / O expander 615 (described later in FIG. 6) provided in the decoration control device 610 will be described.

The effect control device 550 determines the effect contents based on the game data input from the game control device 500. Then, the production control device 550 controls the decoration control device 610 with the decided production content, the address of the decoration control device 610 to be controlled (the address of the I ² CI / O expander 615) and the production content. Production control data including production data to be displayed is output to relay board 600. At this time, the effect control data is output from the connection line SDA to all the decoration control devices 610 connected to the effect control device 550 via the relay board 600. Therefore, the master IC 570 can control all the decoration control devices 610 connected to the master IC 570.

Since a unique address is set in advance in each decoration control device 610, whether or not the address included in the input effect control data matches the set address when the effect control data is input. Determine whether. If it is determined that the address included in the input effect control data matches the set address, the I ² CI / O expander 615 of the decoration control device 610 is included in the effect control data. The decoration device 620 is controlled based on the effect data, and a response signal is output to the master IC 570 immediately after the 8th bit data is input.

As described above, the decoration control device 610 performs control based on a command from the effect control device 550, and therefore, the master IC 570 of the effect control device 550 is the master of the relationship between the effect control device 550 and the decoration control device 610. The I ² CI / O expander 615 of the decoration control device 610 is a slave.

  Although the case where the decoration target of the decoration control device 610 is the decoration device 620 has been described with reference to FIG. 5, the control target of the decoration control device 610 may be the accessory driving SOL 560 or the accessory driving MOT 561.

  FIG. 6 is a block diagram of the decoration control device 610 according to the embodiment of this invention.

  In FIG. 6, the decoration control device 610 (the decoration control device 610 on the lower side in FIG. 6) including the decoration device 620 LED inside the decoration control device 610 and the decoration control device 610 connected to the external decoration device 620. (The decoration control device 610 in the center of FIG. 6) will be described.

  First, the decoration control device 610 provided with LEDs inside the decoration control device 610 will be described.

The decoration control device 610 on the lower side of FIG. 6 includes an I ² CI / O expander 615 and LEDs (decoration device 20). The connection line SDA and the connection line SCL are branched into two in the decoration control device 610, and one is output to the next decoration control device 610 as it is. The other is connected to the I ² CI / O expander 615.

A decoration device 620 to be controlled is connected to the output side of the I ² CI / O expander 615. The output side of the I ² CI / O expander 615 includes ports 0 to 15 described with reference to FIG. Furthermore, all the ports of the decoration control device 610 are connected to the internal LEDs via current limiting resistors R0 to R15 described later with reference to FIG. 8A. Note that the current control resistors R0 to R15 are also provided in the decoration control device 610.

As described above, the I ² CI / O expander 615 matches the address included in the effect control data input from the effect control device 550 and the address set in the I ² CI / O expander 615. Only when this is done, the decoration device 620 connected to the I ² CI / O expander 615 is controlled based on the decoration data included in the effect control data.

  Next, the decoration control device 610 connected to the external decoration device 620 will be described.

The central decoration control device 610 in FIG. 6 includes an I ² CI / O expander 615 and an LED (decoration device 20), and allows current to flow through the LEDs provided on the decoration device substrate 625 connected to the outside of the decoration control device 610. The decoration control device 610 and the decoration device substrate 625 are connected to each other through a connection line for supplying power to the LEDs of the decoration device substrate 625 and a connection wire grounded to the ground.

The decoration device substrate 625 does not include the I ² CI / O expander 615 but is a substrate including only LEDs. In this case, the current limiting resistor (FIG. 8A) connected to the LED provided on the decoration device board 625 is provided on the decoration device board 625, but the decoration control device provided with the I ² CI / O expander 615. 610 may be provided.

It should be noted that the number of connection lines for passing current to these LEDs to be passed from the decoration control device 610 to the decoration device substrate 625 is determined in accordance with the number of LEDs provided on the decoration device substrate 625. . For example, when the decoration device substrate 625 includes two LEDs, two control lines for connecting the LED ^{2 to} the port of the I ² CI / O expander 615 and one power supply line for supplying Vled are included. At least it will be necessary.

The I ² CI / O expander 615 provided in the central decoration control device 610 is also set in the address included in the effect control data input from the effect control device 550 and the I ² CI / O expander 615. The decoration device 620 connected to the I ² CI / O expander 615 is controlled based on the decoration data included in the effect control data only when the address that matches the address is matched. In this case, both the decoration device 620 provided in the central decoration control device 610 and the decoration device 620 provided on the decoration device substrate 625 are controlled by the I ² CI / O expander 615.

In this way, by providing the decoration device substrate 625 and separating a part of the decoration devices (LEDs) from the decoration control device 610, even if the LEDs are arranged at remote locations, a common I ² CI / It can be controlled by the O expander 615.

  Note that the decoration control device 610 may connect and control the accessory driving SOL 560 and the accessory driving MOT 561 in place of the decoration device 620, but details will be described later with reference to FIG. 8B.

FIG. 7 is a block diagram of the I ² CI / O expander 615 according to the embodiment of this invention.

The I ² CI / O expander 615 includes a transistor 630 connected to the connection line SDA, a filter 631 connected to the connection line SDA, a driver 632 connected to the connection line SDA, a filter 633 connected to the connection line SCL, Bus controller 634, output setting register 635, output controller 636, driver 637 connected to ports 0-15 on the output side of I ² CI / O expander 615, transistors 638A-638P connected to ports 0-15 , And a reset signal generation circuit 639.

  The filter 631 is connected to the connection line SDA, removes noise of data input from the connection line SDA, and outputs the data from which noise has been removed to the bus controller 634. When the driver 632 outputs a response signal from the connection line SDA, the driver 632 applies a voltage at which the transistor 630 can operate to the transistor 630.

  When the driver 632 outputs data (response signal) from the connection line SDA, the driver 632 applies a voltage at which the transistor 630 can operate to the transistor 630.

  The transistor 630 uses a field effect transistor (FET) to suppress power consumption, the gate of the transistor 630 is connected to the driver 631, and the drain is applied with a predetermined voltage by a pull-up resistor R (see FIG. 4). Connected to the connected connection line SDA, and the source is grounded.

  If the voltage applied to the gate of the transistor 630 is smaller than a predetermined value for operating the transistor 630, no current flows between the drain and the source. On the other hand, if the voltage applied to the gate of the transistor 630 is greater than or equal to a predetermined value that causes the transistor 630 to operate, a current flows from the drain to which the voltage of the predetermined value is applied to the grounded source. The voltage drops. Note that the transistor 630 has a specification that does not break even when a current of about 10 milliamperes flows from the drain to the source.

  When the driver 632 outputs data (response signal) from the connection line SDA, the driver 632 applies a voltage of a value that allows the transistor 630 to operate to the gate of the transistor 630 so that a current flows between the drain and the source. To do. The driver 632 outputs data from the connection line SDA by repeatedly changing the voltage of the connection line SDA from HIGH to LOW.

  The filter 633 is connected to the connection line SCL, removes noise of data input from the connection line SCL, and outputs the data from which noise has been removed to the bus controller 634.

In addition, the I ² CI / O expander 615, is set a unique address by the address setting terminals A0~A3 provided in the I ² CI / O expander 615 is input to the bus controller 634.

The bus controller 634 determines whether the address of the data input from the connection line SDA matches the address set in the I ² CI / O expander 615, and if it matches, takes in the data, The output setting register 635 is updated with the fetched data.

  In addition, the bus controller 634 changes the signal level of the SCL connection line from LOW to HIGH and takes in the 8th bit data, and then changes the signal level of the SCL connection line from HIGH to LOW. A response signal is output from the connection line SDA to the master IC 570. Further, it is confirmed that the signal level of the SCL connection line changes from LOW to HIGH, and when the signal level of the SCL connection line changes from HIGH to LOW again, the connection line SDA is released. That is, a response signal is output at a timing when the number of changes in the signal level of the SCL connection line from LOW to HIGH becomes nine.

In the output setting register 635, the operation mode of the I ² CI / O expander 615 and the output state of the ports 0 to 15 are set. Further, when the reset signal is input to the output setting register 635, the output setting register 635 is set to an initial state so that no current flows through all the ports 0 to 15.

  Based on the data set in the output setting register 635, the output controller 636 causes the directing device connected to each of the ports 0 to 15 to actually output the output state of the directing device through the port driver 637. To control.

  When a current flows through a port, the driver 637 applies a voltage at which the transistors 638A to 638P connected to the port through which the current flows can operate.

  The gates of the transistors 638A to 638P are connected to the driver 637, the drain is connected to the port terminal connected to the connection line to which the voltage for operating the rendering device is applied as shown in FIGS. 8A and 8B, and the source is grounded Has been.

  If the voltage applied to the gates of the transistors 638A to 638P is smaller than a predetermined value for operating the transistors 638A to 638P, no current flows between the drain and the source. On the other hand, if the voltage applied to the gates of 638A to 638P is equal to or higher than a predetermined value for operating the transistor 638, the power supply Vled shown in FIG. 8A or the power supply Vmot or the power supply Vsol shown in FIG. Current flows to the source grounded through the drain of the transistor 638, so that the output state of the effect device connected to the port terminal can be controlled.

Further, the I ² CI / O expander 615 of the decoration control device 610 can control all the rendering devices connected to the port terminals of the I ² CI / O expander 615 at the same time. ² One rendering device connected to the port terminal of the CI / O expander 615 can be controlled as one group.

Since the I ² CI / O expanders 615 included in each decoration control device 610 are assigned different addresses, the rendering device is divided into a plurality of groups. In other words, the I ² CI / O expander 615 included in each decoration control device 610 is configured as a group unit control unit that can control the effect device in units of groups.

  Therefore, the effect control device 550 that controls the decoration control device 610 functions as a group control unit that controls the group unit control unit in a group-wide manner.

The reset signal generation circuit 639 is connected to a Vcc terminal connected to a connection line Vcc that supplies power to the I ² CI / O expander 615 and a RESET terminal that receives an external reset signal.

The reset signal generation circuit 639 generates a reset signal when the I ² CI / O expander 615 is turned on and the voltage rises to a predetermined value, and the generated reset signal is sent to the bus controller 634 and the output setting register 635. , And the output controller 636.

  Note that when a LOW level reset signal is input from the outside, the reset signal generation circuit 639 outputs a reset signal, but in this embodiment, the RESET terminal is pulled HIGH as shown in FIGS. 8A and 8B. Since the reset signal is not input from the outside, the reset signal generation circuit 639 does not generate a reset signal when an external signal is input.

FIG. 8A is a circuit diagram around the I ² CI / O expander 615 of the decoration control device 610 that controls the decoration device 620 according to the embodiment of this invention.

The I ² CI / O expander 615 includes an NC terminal, a RESET terminal, an SCL terminal, an SDA terminal, a Vcc terminal, an A0 to A3 terminal, and a GND terminal as input terminals, and includes PORT0 to PORT15 as output terminals.

A power source supplied to the I ² CI / O expander 615 is connected to the RESET terminal via a pull-up resistor R. For this reason, the voltage applied to the reset terminal is always maintained HIGH.

  The SCL terminal is connected to the connection line SCL, and the SDA terminal is connected to the connection line SDA.

A power supply supplied to the I ² CI / O expander 615 is connected to the Vcc terminal. Further, a capacitor CP for removing power supply noise is connected to the Vcc terminal.

The A0 to A3 terminals are terminals for setting addresses in the I ² CI / O expander 615. Note that the address of the normal I ² CI / O expander 615 is represented by 4 bits. When the power of the I ² CI / O expander 615 is applied to this terminal, “1” is displayed in the bus controller 634. When this terminal is connected to the ground, “0” is set in the bus controller 634.

Therefore, the address of the I ² CI / O expander 615 shown in FIG. 8A is “0100”, and the address of the I ² CI / O expander 615 shown in FIG. 8B is “0110”. The GND terminal is a terminal for grounding a voltage.

  Each PORT0 terminal to PORT15 terminal is connected to a decoration device 620 including each LED0 to LED15 via current limiting resistors R0 to R15. Note that one LED may be connected to one port as in PORT0, but a plurality of LEDs may be connected to one port as in PORT1-15.

When one LED is provided for all the ports, a maximum of 16 LEDs can be controlled by one I ² CI / O expander 615. If the number of LEDs connected to each port is different, assuming that all LEDs connected in series to one port are one type of LED, one I ² CI / O expander is used. By 615, up to 16 kinds of LEDs can be controlled.

  When a voltage is applied from the driver 637 to the gates of the transistors 638A to 638P (see FIG. 7) connected to the PORT0 terminal to the PORT15 terminal, a current flows from the drain to the source of the transistors 638A to 638P to which the voltage is applied. Thus, a current flows through the LED0 to LED15 connected to the PORT0 terminal to the PORT15 terminal, and each of the LED0 to LED15 lights up.

  On the other hand, if the driver 637 does not apply a voltage to the gates of the transistors 638A to 638P, no current flows through each LED0 to LED15, and each LED0 to LED15 is not lit.

In addition, since it is possible to connect a motor or a solenoid to the PORT0 terminal to the PORT15 terminal of the I ² CI / O expander 615 instead of the LED, the motor is used by using the I ² CI / O expander 615. A case where a solenoid is driven will be described.

In the present embodiment, the signal terminals of the respective phases of the accessory driving MOT 561 are connected to the PORT0 terminal to the PORT3 terminal.

  When a voltage is applied from the driver 637 to any one of the gates of the transistors 638A to 638D connected to the PORT0 terminal to the PORT3 terminal connected to the accessory driving MOT561, the transistors 638A to 638D to which the voltage is applied are applied. The current can flow from the drain to the source, the current flows to the accessory driving MOT 561 connected to the PORT0 terminal to the PORT3 terminal, and the accessory driving MOT561 is driven.

  The connection lines connecting the PORT0 terminal to the PORT3 terminal and the accessory driving MOT 561 are branched, and one of the branched connection lines is connected to the power supplied to the accessory driving MOT 561 via the diode D and the Zener diode ZD. Connected.

  The PORT terminal 15 is connected to the accessory driving SOL 560. When a voltage is applied from the driver 637 to the gate of the transistor 638P connected to the PORT15 terminal connected to the accessory drive SOL560, a current can flow from the drain to the source of the transistor 638P to which the voltage is applied. Thus, a current flows through the accessory driving SOL 560 connected to the PORT 15 terminal, and the accessory driving AOL 560 is driven.

In FIG. 8B, with respect to I ² CI / O Aix although both character object drive MOT561 and character object drive SOL560 Panda 615 are connected, one I ² CI / O expander 615, the character object drive A configuration in which at least one of the MOT 561 and the accessory driving SOL 560 is connected may be used.

For example, an I ² CI / O expander 615 as a group that controls only the stepping motor may be provided exclusively, or an I ² CI / O expander 615 as a group that controls only the solenoid may be provided exclusively. . With such a configuration, it is possible to control the rendering devices belonging to the same group at the same timing, and therefore it becomes possible to group and control only the rendering devices that require high-speed processing.

  One of the bypass capacitors 1062 is connected to the ground as shown in FIG. This ground is constituted by a GND pattern 1201 that is an insulator on the substrate of the decoration control device 610.

That is, the bypass capacitor 1062 is disposed closer to the I ² CI / O expander 615 than other circuits.

  FIG. 13 is an explanatory diagram of the slave address 1300 included in the data output from the effect control device 550 to the decoration control device 610 according to the embodiment of this invention.

  The slave address 1300 includes a fixed address part 1301 composed of upper 3 bits and a variable address part 1302 composed of lower 5 bits.

The fixed address portion 1301 is an address for which “110” is preset and the I ² CI / O expander 615 cannot be changed.

Variable address portion 1302 is a configurable address I ² CI / O expander 615, corresponding to a pattern that is set to A0~A3 terminal of I ² CI / O expander 615 to be controlled 4 A bit I ² CI / O expander address 1303 and 1-bit R / W identification data 1304 indicating whether the data is a read request or a write request are included.

  Since the effect control data output from the effect control device 550 to the decoration control device 610 is a write request, “0” is normally registered in the R / W identification data 1304.

FIG. 14 is an explanatory diagram of the I ² CI / O expander address table 1400 according to the embodiment of this invention.

The I ² CI / O expander address table 1400 is a table managed by the master IC 570. The I ² CI / O expander address table 1400 shows a correspondence relationship between the slave address 1401 and the I ² CI / O expander address 1402.

The slave address 1401 stores the slave address of the decoration control device 610 specified by the effect control device 550 as a transmission / reception target. As described above with reference to FIG. 13, the slave address is configured by combining a fixed address portion composed of upper 3 bits, a 4-bit I ² CI / O expander address, and 1-bit R / W identification data. .

In the I ² CI / O expander address 1402, as described above with reference to FIGS. 8A and 8B, a 4-bit I ² CI / O expander address corresponding to each slave address is registered.

However, among the I ² CI / O expander addresses, the address “1000” and the address “1011” cannot be used as unique addresses for identifying the I ² CI / O expanders 615 from each other.

  “1000” is used as a default value at the time of power-on of an address (all call address) specified when outputting commands to all the decoration control devices 610. “1011” is an address used when the device is reset by software.

As described above, since the number of addresses that can be set in the I ² CI / O expander 615 of the decoration control device 610 is 14, the effect control device 550 can control the 14 I ² CI / O expanders 615. . In addition, since one decoration control device 610 includes PORT0 to PORT15, it can control 16 (in other words, 16 types) LEDs. Therefore, the production control device 550 can control 224 (in other words, 224 types) LEDs.

  FIG. 15 is a flowchart of processing by the effect control device 550 according to the embodiment of this invention.

  In the processing shown in FIG. 15, for example, the decoration control device 610 is divided into groups for each type of effect device, such as a group of decoration devices 620, a group of accessory driving SOL 560, and a group of accessory driving MOT 561. Control the production devices belonging to the divided groups. As an example, it is assumed that there are eight groups of decoration devices 620, which are groups A to H of light-emitting effect devices, respectively. Further, it is assumed that the accessory driving SOL560 and the accessory driving MOT561 are in the same group, and this is a group of movable effect devices.

  The processing of the effect control device 550 shown in FIG. 15 is executed by the CPU 551 of the effect control device 550.

  When the effect control device 550 is turned on, the effect control device 550 first executes the processing of steps 1501 to 1509, and synchronizes with the image update cycle from the VDP 556 in the processing of step 1510 (for example, 1/30). It waits until the synchronization signal (second cycle) is input to the CPU 551 as an interrupt signal. When a synchronization signal synchronized with the image update cycle is input from the VDP 556 to the CPU 551 as an interrupt signal, the processing in steps 1502 to 1509 is repeatedly executed.

First, the effect control device 550 initializes the effect control device 550 (1501). At this time, the master IC 570 is initialized via the input / output I / F 558, and further, the master IC 570 is instructed to reset all the I ² CI / O expanders 615 to the initial state.

  Next, in order to display the image on the display device 53, the effect control device 550 outputs data serving as a command for displaying the image on the VDP 556 (1502).

  Then, the effect control device 550 outputs effect control data for controlling the accessory driving SOL 560 and the accessory driving MOT 561 according to the gaming state to the decoration control device 610 that controls the accessory driving SOL 560 and the accessory driving MOT 561. (1503).

  Then, the production control device 550 outputs sound control data to the sound LSI 557 in order to output sound from the speaker 30 according to the gaming state, and causes the sound LSI 557 to output sound from the speaker 30 based on the sound control data ( 1504).

  Then, the production control device 550 refers to the slave selection order table 1600 shown in FIG. 16, selects the slave selection order of the time division counter that is updated each time a synchronization signal is input from the VDP 556 to the CPU 551, and selects the selected slave. Based on the order, the effect control data is output from the master IC 570 to the decoration control device 610 of each group that controls the decoration device 620 (1505).

  The time division counter takes a value from “0” to “3”, and when a synchronization signal is input from the VDP 556 to the CPU 551, the CPU 551 increments the time division counter. When the time division counter is “3” and the synchronization signal is input from the VDP 556 to the CPU 551, the CPU 551 updates the time division counter to “0”.

  Next, the effect control device 550 edits the data output next to the VDP 556 (1506), and the effect control data output next to the decoration control device 610 that controls the accessory driving SOL 560 and the accessory driving MOT 561. Edit (1507).

  The effect control device 550 edits the sound control data output to the sound LSI 557 (1508), and edits the effect control data output next to the decoration control device 610 of each group that controls the decoration device 620 ( 1509), and waits until a synchronization signal is input from the VDP 556 to the CPU 551.

  When the synchronization signal is input from the VDP 556 to the CPU 551, the effect control device 550 updates the time division counter (1510), and proceeds to the process of step 1502.

As described above, in the process according to FIG. 15, the effect control data is transmitted from the master IC 570 of the effect control device 550 to the I ² CI / O expander 615 of the decoration control device 610 in synchronization with the cycle of updating the image of the display device 53. The I ² CI / O expander 615 controls the effect device 620 based on the received effect control data, so that the effect on the display device 53 and the effect on the effect device 620 are harmonized, giving the player a sense of incongruity. Because there is no, it can raise interest.

  In the process of FIG. 15, the master IC 570 first outputs the effect control data to the decoration control device 610 that controls the accessory driving SOL 560 and the accessory driving MOT 561, and later controls the decoration device 620. Production control data is output. For this reason, the variation in the elapsed time from the generation timing of the synchronization signal is small for the accessory driving MOT 561 and the accessory driving MOT 561 and large for the decoration device 620. Therefore, the timing at which the accessory driving MOT 561 and the accessory driving MOT 561 are controlled becomes more accurate, and the movable accessory 60 that attracts the player's attention can be accurately controlled with respect to the gaming state, which makes the player feel uncomfortable. Don't give.

  FIG. 16 is an explanatory diagram of the slave selection order table 1600 according to the embodiment of this invention.

  The slave selection order table 1600 is stored in the control ROM 552. In the slave selection order table 1600, the control order of the groups of the decoration control devices 610 to be controlled is registered for each value of the time division counter.

  In the following description, as described above, the movable effect device group is a group of decoration control devices 610 that control the accessory driving SOL 560 and the accessory driving MOT 561, and the light-emitting effect device groups A to H are: This is a group of decoration control devices 610 that control the decoration device 620.

  The slave selection order table 1600 includes a time division counter 1601 and a slave selection order 1602.

  Values of “0” to “3” are registered in the time division counter 1601. In the slave selection order 1602, the order of the decoration control device 620 in which the master IC 570 outputs the effect control data is registered. Here, in the process of “motor / solenoid-related output” in step 1503 of FIG. 15, the movable effect device group is controlled, and then “light-emitting device related output corresponding to the time division counter” in step 1505 of FIG. This process indicates that only the group corresponding to the time division counter among the light-emitting effect device groups A to H is controlled in the order from the top to the bottom of the table.

  The slave selection order 1602 in the case where the time division counter 1601 is “0” includes a movable effect device group, a light emission effect device group A, a light emission effect device group B, a light emission effect device group D, and a light emission effect. Device group H is registered. The CPU 551 controls the movable effect device group, the light-emitting effect device group A, the light-emitting effect device group B, the light-emitting effect device group D, and the light-emitting effect device group H in this order.

  In the slave selection order 1602 in the case where the time division counter 1601 is “1”, the movable effect device group, the light emission effect device group A, the light emission effect device group C, and the light emission effect device group E are registered. Yes.

  In the slave selection order 1602 in the case where the time division counter 1601 is “2”, the movable effect device group, the light emission effect device group A, the light emission effect device group B, and the light emission effect device group F are registered. Yes.

  In the slave selection order 1602 in the case where the time division counter 1601 is “3”, the movable effect device group, the light emission effect device group A, the light emission effect device group C, and the light emission effect device group G are registered. Yes.

  In other words, the effect control data is first output from the master IC 570 to the decoration control device 610 of the movable effect device group, and after the effect control data is output to the decoration control device 610 of the movable effect device group, the light emission effect The effect control data is output to the decoration control device 610 of the device group.

  As will be described in detail with reference to FIG. 17, the master IC 570 first outputs the effect control data to the decoration control device 610 to be controlled, and when an ACK response signal is input from the decoration control device 610 to be controlled. Then, the decoration control device 610 to be the next control target is selected and the production control data is output.

  Therefore, if the ACK response signal is unconditionally input from the decoration control device 610 to the master IC 570, the effect control data can be transmitted from the master IC 570 to the decoration control device 610 in synchronization with the synchronization signal. However, if the data communication cannot be transmitted correctly due to noise or the like, an ACK response signal is not input from the control target decoration control device 610 (a NACK response signal is input). Processing to output the same data to the decoration control device 610 to be controlled is performed.

  For this reason, as the decoration control device 610 has the slave selection order later, the timing at which the effect control data transmitted from the master IC 570 is input tends not to be periodic. In other words, there is a time difference between the generation timing of the synchronization signal and the transmission timing of the effect control data, and the variation in the time difference becomes larger as the decoration control device 610 has the slave selection order later.

  In addition, since the effect device controlled by the decoration control device 610 of the movable effect device group moves according to the game state, it attracts the player's attention more than the decoration device 620 that emits light according to the game state.

  Therefore, the master IC 570 first outputs effect control data to the decoration control device 610 of the movable effect device group so that there is no delay in the control timing of the effect device controlled by the decoration control device 610 of the movable effect device group. Like to do.

  Next, the control frequency of the decoration control device 610 for each group based on the slave selection order table 1600 will be described.

  Since the movable effect device group and the light emission effect device group A are registered in all of the time division counters, they are controlled each time a synchronization signal from the VDP 556 is input to the CPU 551. Further, since the light-emitting effect device group B and the light-emitting effect device group C are registered when the time division counter is “1” and “2”, the synchronization signal from the VDP 556 is 2 to the CPU 551. Once input, it is controlled once. Further, since the light-emitting effect device groups D to H are registered when the time division counter is any one of “0” to “3”, the synchronization signal is input from the VDP 556 to the CPU 551 four times. It is controlled once.

  The light-emitting effect device groups A to H are appropriately assigned according to the control frequency of the LEDs belonging to the group. For example, a group of LEDs that require a high-speed luminance change is assigned as group A, and groups of LEDs that are sufficient for a low-speed luminance change are assigned groups D to H.

  As a result, the control frequency of the decoration control device 610 of the movable effect device group becomes equal to or higher than the control frequency of the decoration control device 610 of the light-emitting effect device groups B to H. For this reason, since the control interval of the effect device controlled by the decoration control device 610 of the movable effect device group having a high degree of attention of the player can be subdivided, it is possible to produce an effect with less discomfort to the player.

  Also, every time a synchronization signal is generated, the master IC 570 does not transmit the effect control data to all of the light-emitting effect device groups A to H, but some light-emitting effect device groups corresponding to the time-division counter are selected. Selection control data is transmitted. For this reason, the ratio of the transmission time of the production control data occupying within the period of the synchronization signal is reduced, and the processing time can be made efficient.

  In the present embodiment, the control frequency of the decoration control device 610 of the movable effect device group is controlled at the timing of the synchronization signal synchronized with the image update period output from the VDP 556, but the light emission effect device group. Only the control frequencies A to H may be synchronized with the synchronization signal, and the control frequency of the decoration control device 610 of the movable effect device group may be higher (for example, a cycle of 2 milliseconds).

  FIG. 17 is a flowchart of slave output processing by the master IC 570 according to the embodiment of this invention.

  When the process of step 1503 shown in FIG. 15 is executed, a slave to be a movable effect device group is selected, and this slave output process is executed by the controller 574 of the master IC 570. Further, when the processing of step 1505 shown in FIG. 15 is executed, the slaves of the light-emitting effect device group corresponding to the time division counter described above with reference to FIG. 16 are selected in order, and each time the controller 574 of the master IC 570 is selected. This slave output process is executed.

  First, the master IC 570 initializes an ACK counter for counting the number of times an ACK response signal from the decoration control device 610 has not been received to 0 (1700). Next, the master IC 570 changes the signal levels of the connection line SDA and the connection line SCL to a signal level indicating a start condition (1701).

  Specifically, the master IC 570 outputs a signal indicating a start condition by changing the signal level of the connection line SDA from HIGH to LOW while maintaining the signal level of the connection line SCL at HIGH.

  When a start condition is input to the decoration control device 610, the decoration control device 610 initializes a signal change counter (not shown) for counting the signal level of the connection line SCL to zero.

  Note that, after outputting a signal indicating the start condition, the master IC 570 changes the level of the connection line SCL to LOW in order to send data to the decoration control device 610 to be controlled.

  Next, the master IC 570 outputs the slave address data of the decoration control device 610 to be controlled via the connection line SDA while changing the signal level of the connection line SCL (1702).

  Since the address data output in the process of step 1702 is an 8-bit data string as shown in FIG. 13, the address data is output by one output process (output while the connection line SCL changes to HIGH for 8 times). Is output.

When the address data output in the process of step 1702 is input to the decoration control device 610, the I ² CI / O expander 615 of the decoration control device 610 receives the input address data and the address set in itself. It is determined whether or not.

The I ² CI / O expander 615 in which an address that matches the input address data is set immediately after the connection line SCL is changed from LOW to HIGH for the eighth time, A response signal is output from the connection line SDA to the master IC 570 when the connected connection line SCL changes to the LOW level.

  Next, the master IC 570 confirms whether or not an ACK response signal is input to the master IC 570 within a predetermined time after the address data is output in the processing of step 1702 (1703).

  Depending on whether or not an ACK response signal is input, the process branches into the following three (1704).

  First, when the ACK response signal is not input within a predetermined time after the address data is output for the first time in the processing of step 1702 (when the NACK response signal is input while the ACK counter is 0), The master IC 570 proceeds to the processing in step 1714 in order to output the address data again. In the process of step 1714, the ACK counter is updated by +1 in order to count that the reception of the ACK response signal has failed, and the process returns to step 1701.

  Second, for the first time, an ACK response signal corresponding to the address data output in the processing of step 1702 is not input within a predetermined time, and an ACK response is returned within a predetermined time after the address data is output again in the processing of step 1702. When the signal is not input (when the NACK response signal is input while the ACK counter is 1), the master IC 570 abnormally ends the slave output processing (1705). In this case, data transmission to the decoration control device 610 selected this time is stopped, the next decoration control device 610 is selected, and the slave output process is executed again from the beginning.

  Third, if an ACK response signal is input within a predetermined time after the address data is output for the first time in the process of step 1702, or again within a predetermined time after the address data is output for the first time in the process of step 1702. When an ACK response signal is input, the master IC 570 acquires 8-bit data as data to be output first from the data stored in the output BUF 572, and prepares output of the acquired data. (1706).

  Then, the master IC 570 outputs the acquired data from the connection line SDA (1707).

Then, the I ² CI / O expander 615 of the decoration control device 610 in which the address data output in the process of step 1702 matches the address set to itself is used to convert the data output in the process of step 1707 into the connection line. Take in when SCL changes from LOW to HIGH. Then, the I ² CI / O expander 615 of the decoration control device 610 captures data when the connection line SCL changes from LOW to HIGH for the eighth time, and then the connection line SCL changes from HIGH to LOW. As a trigger, a response signal is output from the connection line SDA to the master IC 570.

  Next, the master IC 570 confirms whether or not an ACK response signal is input to the master IC 570 within a predetermined time after the data is output in the processing of step 1707 (1708).

  Depending on whether or not an ACK response signal is input, the process branches into the following three (1709).

  First, when the ACK response signal is not input within a predetermined time after the address data is output for the first time in the processing of step 1702 (when the NACK response signal is input with the ACK counter being 0). The master IC 570 proceeds to the processing of step 1714 in order to output the address data again. In the process of step 1714, the ACK counter is updated by 1 to count that the reception of the response signal has failed, and the process returns to step 1701.

  Second, the data response signal output in step 1707 for the first time is not input within the predetermined time, and the ACK response signal is input within the predetermined time after the data is output again in step 1707. If not (when the NACK response signal is input while the ACK counter is 1), the master IC 570 terminates the slave output processing abnormally (1710). In this case, data transmission to the decoration control device 610 selected this time is stopped, the next decoration control device 610 is selected, and the slave output process is executed again from the beginning.

  Third, if an ACK response signal is input within a predetermined time after the data is output for the first time in the process of step 1707, or an ACK response is received within a predetermined time after the data is output again in the process of step 1707. If a signal is input, the master IC 570 determines whether all data stored in the output BUF 572 has been output (1711).

  If it is determined in step 1711 that the data stored in the output BUF 572 is not output, the master IC 570 outputs the next 8-bit data stored in the output BUF 572 next. Obtained as data, prepares output of the obtained data (1712), and returns to the processing of step 1706.

  On the other hand, if it is determined in step 1711 that all data stored in the output BUF 572 has been output, the master IC 570 changes the signal levels of the connection line SDA and the connection line SCL to the signal level indicating the stop condition. (1713), and the slave output process is terminated.

  In the processing of step 1713, specifically, the master IC 570 outputs a signal indicating a stop condition by changing the signal level of the connection line SDA from LOW to HIGH while maintaining the signal level of the connection line SCL at HIGH. To do.

  In the processing according to FIG. 17, the master IC 570 determines the success or failure of the data transfer by fetching the response signal from the decoration control device 610 after outputting the 8-bit data. When the NACK response signal is input to the master IC 570), the output data is output again only once, so that the data can be output to the decoration control device 610 as reliably as possible, and the malfunction of the rendering device is prevented. it can. Further, by outputting the output data once again, it is possible to prevent the data transmission time from becoming longer than necessary.

  In the process of FIG. 17, when the master IC 570 transmits the start condition in the process of step 1701, the connection line SDA needs to be HIGH, but the connection line SDA is LOW due to the influence of noise or the like. There may be a case where the state remains unchanged.

In the present embodiment, only the slave address that the master IC 570 transmits to the I ² CI / O expander 615 of the decoration control device 610 has R / W identification data “0” (means writing). (See FIG. 13), but may be transmitted to the I ² CI / O expander 615 in a state where the R / W identification data is “1” (meaning reading) due to the influence of noise or the like. is there.

In this case, the I ² CI / O expander 615 enters the read mode, and the connection line SDA is transferred from the I ² CI / O expander 615 to the master IC 570 in response to the signal level of the connection line SCL being changed by the master IC 570. A process for transmitting data bit by bit through the network is performed.

At this time, each time the I ² CI / O expander 615 transmits 8-bit data, the I ² CI / O expander 615 performs a process of receiving an acknowledge signal from the master IC 570 via the connection line SDA. The data transmission is performed, and thereafter, the 8-bit data transmission and the acknowledge signal confirmation are repeated. During this time, the connection line SDA is occupied by the I ² CI / O expander 615.

On the other hand, if the I ² CI / O expander 615 cannot receive an acknowledge signal from the master IC 570 via the connection line SDA after 8-bit data transmission, the I ² CI / O expander 615 releases the connection line SDA and stops data transmission. When the I ² CI / O expander 615 receives an acknowledge signal from the master IC 570 via the connection line SDA, the I ² CI / O expander 615 interprets that the acknowledge signal is received if the connection line SDA is at the LOW level. If SDA is HIGH, it is interpreted that no acknowledge signal is received.

Therefore, when the data from the master IC 570 changes due to the influence of noise or the like, and the I ² CI / O expander 615 that receives the changed data and enters the read mode is generated, the connection line SDA is changed. It will not be released forever.

In such a case, the signal level of the connection line SDA remains LOW, and the master IC 570 and the I ² CI / O expander 615 of the decoration control device 610 originally intended for transmission Cannot communicate with each other via the connection line SDA.

  Therefore, the master IC 570 determines whether the signal level of the connection line SDA is HIGH in order to determine whether or not the data can be output from the connection line SDA before outputting the signal indicating the start condition in the process of step 1701. It is determined whether or not.

  When it is determined that the signal level of the connection line SDA is not HIGH, data cannot be output from the connection line SDA. Therefore, the driver 576A does not apply an operable voltage to the transistor 578A without turning on the transistor 578A (connection line With the SDA released, the signal level of the connection SCL is changed at least nine times.

By performing such processing, the I ² CI / O expander 615 that has entered the read mode outputs data to the connection line SDA in accordance with the change in the signal level of the connection SCL. The timing for confirming the acknowledge signal from the master IC 570 is generated while the change is made at least nine times. At this time, since the connection line SDA is released, it becomes HIGH level, and the I ² CI / O expander 615 that has entered the read mode determines that it has not received an acknowledge signal. Will be released.

  Note that this process may be performed not only before the signal indicating the start condition is output but also before the master IC 570 outputs data to the decoration control device 610. Specifically, it may be executed before the processing of steps 1702, 1707, and 1713.

In this way, the connection line SDA is forcibly released from the I ² CI / O expander 615 of the decoration control device 610 in the read mode, so that the signal level of the connection line SDA is maintained at HIGH. .

  FIG. 18 is an explanatory diagram of a start condition and a stop condition for data output from the master IC 570 according to the embodiment of this invention via the connection line SDA and the connection line SCL.

  The signal level of the connection line SCL is normally set to HIGH. When the master IC 570 outputs data to the decoration control device 610, the master IC 570 changes the signal level of the connection line SCL from LOW to HIGH. It acts as a strobe signal for taking in the data of the connection line SDA.

  The connection line SDA normally has a signal level of HIGH, and data is output from the connection line SDA in accordance with the clock signal of the connection line SCL.

  Master IC 570 changes the signal level of connection line SDA from HIGH to LOW while maintaining the signal level of connection line SCL at HIGH, and outputs a signal that is a start condition indicating that data output starts. .

The I ² CI / O expander 615 of the decoration control device 610 recognizes that data output starts when a signal serving as a start condition is input from the connection line SDA and the connection line SCL.

  The master IC 570 changes the signal level of the connection line SDA from LOW to HIGH while maintaining the signal level of the connection line SCL at HIGH, and outputs a signal indicating a stop condition indicating that data output is completed. .

The I ² CI / O expander 615 of the decoration control device 610 grasps that the output of data ends when the stop condition is input.

  FIG. 19 is a timing chart at which the decoration control device 610 to which the data output from the master IC 570 according to the embodiment of the present invention is input outputs a response signal.

  The decoration control device 610 counts the number of changes in the signal level of the connection line SCL after the start condition is satisfied, and takes in data input from the connection line SDA in accordance with the clock signal of the connection line SCL.

  Then, the decoration control device 610 outputs a response signal to the master IC 570 via the connection line SDA immediately after the start condition is satisfied and immediately before the signal line change number of the connection line SCL reaches nine. In other words, the decoration control device 610 receives a response signal via the connection line SDA when the signal level of the connection line SCL changes from HIGH to LOW after taking the 8th bit data from the connection line SDA. Output.

  As shown in the figure, a response signal (ACK response signal) indicating that the data has been successfully received is indicated by a LOW level, and a response signal (NACK response signal, FIG. (Corresponding to no ACK output) is indicated by a HIGH level.

  Further, when the signal level of the connection line SCL changes eight times after the start condition is satisfied, the master IC 570 waits for a response signal from the decoration control device 610 by releasing the connection line SDA. Then, the master IC 570 changes the signal level of the connection line SCL while releasing the connection line SDA, and takes in the response signal from the decoration control device 610.

  FIG. 20 is a timing chart of signal levels of the connection line SDA and the connection line SCL when the master IC 570 according to the embodiment of the present invention outputs effect control data.

  First, when starting to output the production control data, the master IC 570 changes the signal level of the connection line SDA from HIGH to LOW while maintaining the signal level of the connection line SCL at HIGH. A signal indicating that the data is to be output is notified to the decoration control device 610.

  Next, the master IC 570 outputs the address of the decoration control device 610 to be controlled, consisting of a total of 7 bits. Next, the master IC 570 outputs data indicating whether the write request is a read request to the eighth bit.

  The master IC 570 receives a response signal from the decoration control device 610 when the signal level of the connection line SCL becomes HIGH for the ninth time. Therefore, if the response signal is an ACK response signal, the signal level of the connection line SDA is LOW. If the response signal is NACK, the signal level of the connection line SDA changes to HIGH.

  Next, after the output of the address data, the master IC 570 outputs the presentation control data with a bit number that is a multiple of 8. Master IC 570 outputs the ninth bit of the effect control data after outputting the eighth bit of the effect control data and waiting for an ACK response signal to be input. Thereafter, when data of a bit corresponding to a multiple of 8 is output, after confirming that an ACK response signal is input, a (multiple of 8 + 1) th bit is output and all data is output. Repeat until.

  Note that if the master IC 570 outputs a bit that is a multiple of 8 of the production control data and does not receive an ACK response signal even after a predetermined time has elapsed, the master IC 570 receives the address data again via the connection line SDA. The output control data is output again from the first bit while confirming the ACK response signal.

  The master IC 570 outputs the last bit data of the effect control data, waits for an ACK response signal to be input, and outputs a signal indicating a stop condition.

  In FIG. 20, a total of 24 bits (slave address 8 bits, presentation control data 16 bits) are output from when the signal indicating the start condition is output until the signal indicating the stop condition is output. However, it may be 24 bits or more, or 24 bits or less.

FIG. 21 shows a case in which the master IC 570 according to the embodiment of the present invention designates a slave address and sets data in the decoration control device 610 between the master IC 570 and the I ² CI / O expander 615. It is a figure explaining the format of data.

The 8-bit data 2101 that is output first includes an address “A0 to A6” of the decoration control device 610 that is the target of data transmission, and a 1-bit R that indicates whether the data is a read request or a write request. / W identification data. Among the addresses “A0 to A6”, “A4 to A6” are fixed address portions having a value “110”, and “A0 to A3” are set to terminals A0 to A3 of the I ² CI / O expander 615. This corresponds to the address that has been set (see FIG. 13).

Next, in the output 8-bit data 2102, the output setting register 635 has a control register for designating an area allocated to the output setting register 635 (see FIG. 7) of the I ² CI / O expander 615. Contains data. Specifically, it consists of a register address consisting of 5 bits “D0 to D4” and an automatic writing parameter consisting of 3 bits “AI0 to AI2”. The register address is information for designating an area of the output setting register 635, and designates an address of an area to be written or read by the master IC 570. The automatic writing parameter is a parameter for designating whether the master IC 570 accesses only the area designated by the register address or includes the area adjacent to the designated area.

  Next, the actually written data is allocated to the output setting register 635 area specified by the control register data in the bit data 2103 which is a multiple of 8 to be output.

FIG. 22 is an explanatory diagram illustrating specific numerical examples of data exchanged between the master IC 570 and the I ² CI / O expander 615 when the decoration control device 610 according to the embodiment of the present invention is subjected to decoration control. It is. Data is transmitted and received between the master IC 570 and the I ² CI / O expander 615 according to the data format of FIG.

“1101100” indicating the slave address of the I ² CI / O expander 615 of the decoration control device 610 is assigned to the 8-bit data 2201 output first.

The 8-bit data 2202 to be output next includes the address of the output setting register 635 of the I ² CI / O expander 615 of the decoration control device 610 assigned to set the LED output data. Here, the LEDOUT0 register (address = 10100), which is an area for setting the light emission state of the LEDs connected to the PORT0 terminal to the PORT3 terminal of the I ² CI / O expander 615, is designated.

Next, the output 8-bit data 2203 includes data indicating the content of decoration control performed by the decoration control device 610 on the decoration device 620. Specifically, data set in the LEDOUT0 register is assigned. As a result, the light emission state (lighted, extinguished, blinking, etc.) of the LEDs connected to the PORT0 to PORT3 terminals of the I ² CI / O expander 615 is designated, and the LEDs emit light in the designated state.

In this way, the light emission state of the LED PORT0 terminal ~PORT3 terminal I ² CI / O expander 615 is controlled, the other PORT terminal I ² CI / O expander 615 (PORT4~PORT15) also Control can be performed by specifying the value of the control register data 2202 and setting the output data 2203. Even if a motor or solenoid is connected to the PORT terminal, the same control is performed.

  FIG. 23 is an explanatory diagram of the connection between the master IC 570 and the decoration control device 610 when the effect control device 550 according to the embodiment of the present invention includes a plurality of master ICs 570.

  In FIG. 23, the production control device 550 includes three master ICs 570A to 570C.

  The master IC 570A is connected to the relay board 600A, and the relay board 600A is connected in series to the decoration control devices 610A to 610C and is connected in series to the decoration control devices 610D to 610F.

  The master IC 570B is connected to the relay board 600B, and the relay board 600B is connected in series to the decoration control devices 610G to 610I and is connected in series to the decoration control devices 610J to 610L.

  The master IC 570C is connected to the relay board 600C, and the relay board 600C is connected in series to the decoration control devices 610M to 610O and is connected in series to the decoration control devices 610P to 610R.

  Here, the decoration control device 610 group connected to one master IC 570 is referred to as a system. Specifically, in the case of the master IC 570A, the system is the relay board 600A and the decoration control devices 610A to 610F.

  Since the master IC 570 can output data to the connected decoration control device 610, the master IC 570 can control the connected decoration control device 610.

With this configuration, there is no limit on the number of I ² CI / O expanders 615 that can be controlled by one master IC 570 (up to 14 as shown in FIG. 14), and a variety of effects can be controlled. Can be expected to do.

  The embodiment disclosed this time is illustrative in all points and is not restrictive.
