Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a schematic structural diagram illustrating a voice terminal according to an exemplary embodiment, and as shown in fig. 1, the voice terminal includes a first MCU110, a second MCU120 and a Flash 130.

The first MCU110 is generally a chip in a voice terminal, which has a clock circuit, a power circuit, etc., a memory space, and peripheral interfaces such as UART, SPI, etc. The second MCU120 is typically a chip in the voice terminal having circuits such as a clock circuit and a power supply circuit, a memory space, and peripheral interfaces such as UART and SPI. The MCU is not limited in this embodiment.

The first SPI140 of the first MCU110 is connected to the third SPI160 of the second MCU120, and the second SPI150 of the first MCU110 and the fourth SPI170 of the second MCU120 are connected to the SPIs 180 of the Flash130, respectively.

The SPI includes four pins, namely, SCK (Serial Clock), MISO (Master Input Slave Output), MOSI (Master Output Slave Input), and CS (Chip Select). In this embodiment, the first MCU110 includes the first SPI140 and the second SPI150, the second MCU120 includes the third SPI160 and the fourth SPI170, the Flash130 includes the SPI180, the four pins of the first SPI140 are respectively connected to the four pins of the third SPI160, and the four pins of the second SPI150 are respectively connected to the four pins of the fourth SPI 170. Four pins of second SPI150 are correspondingly connected to four pins of SPI180, respectively, and four pins of fourth SPI170 are correspondingly connected to four pins of SPI180, respectively.

In this embodiment, the states of the SPI include an idle state and a working state, and when the state of the SPI is the idle state, the SPI cannot transmit data, that is, does not work; when the state of the SPI is working, the SPI can transmit data.

In this embodiment, the first SPI140 and the third SPI160 are both in a working state, so that real-time communication between the first MCU110 and the second MCU120 can be realized.

Because Flash only has one SPI, Flash can only communicate with one MCU at the same time. Namely, the SPI180 and the second SPI150 can both be in a working state, and the fourth SPI170 is in an idle state, so that the Flash130 and the first MCU110 can communicate with each other; or, both the SPI180 and the fourth SPI170 are in a working state, and the second SPI150 is in an idle state, so that the Flash130 and the second MCU120 are communicated.

In this embodiment, the UART interface 190 of the first MCU110 is connected to the communication interface of another terminal, so as to implement communication between the other terminal and the Flash 130. For example, the first MCU110 may read data from other terminals and forward the voice data to the Flash 130; or read data from Flash130 and forward the data to other terminals.

In this embodiment, the data stored in Flash130 includes at least one of a voice function, a voice recognition library, a voice playing library, recording data, MIDI (Musical Instrument Digital Interface) data, a firmware library, and description information.

The voice function refers to some function that may be called by the first MCU110 or the second MCU120 to perform a voice operation. For example, the voice function may include a play function PlaySound () or a record function WaveIn ().

The voice playing library contains voice data to be played. For example, the voice playing library may include a welcome language when the voice terminal is started, an end language when the voice terminal is turned off, and the like, which is not limited in this embodiment.

The recording data includes data obtained by recording.

MIDI data is sound effect data. For example, MIDI data are "Duo", "Rui", "Mi", and the like.

The firmware library contains drivers such as an operating system and the like. The first MCU and the second MCU can call programs in the firmware library.

The description information includes information describing the firmware library, for example, the description information includes a version number, and the like, which is not limited in this embodiment.

In this embodiment, the first MCU110 and the second MCU120 may be the same MCU, that is, the first MCU110 and the second MCU120 control the Flash130 in the same operation; or, the first MCU110 is a master MCU, and the second MCU120 is a slave MCU; the master MCU is used for updating data in the Flash130, and the slave MCU is used for executing voice operation on the Flash 130.

When the first MCU110 is a master MCU and the second MCU120 is a slave MCU, the running speed of the first MCU110 is higher than that of the second MCU120, so that the first MCU110 with high running speed updates data in the Flash130 to improve the updating efficiency; and performing voice operation on the Flash130 through the second MCU120 with a slow operation speed.

In summary, in the terminal communication method provided by the present disclosure, the first MCU sends the first instruction to the second MCU through the first SPI; the first instruction is used for switching the fourth SPI of the second MCU from a working state to an idle state; the first MCU sends a second instruction, and the second instruction is used for switching the second SPI of the first MCU from an idle state to a working state; the first MCU is communicated with the Flash memory Flash through the second SPI; the second SPI and the fourth SPI are respectively connected with the Flash and used for carrying out data communication with the Flash, so that data in the Flash can be shared by the two MCUs, the problem that the data in the Flash cannot be shared when one MCU reads the data in the Flash is solved, and the effect of improving the utilization rate of the data in the Flash is achieved.

Fig. 3 is a flowchart illustrating a terminal communication method applied to the voice terminal shown in fig. 1 according to an exemplary embodiment, and the terminal communication method includes the following steps, as shown in fig. 3.

In step 301, a voice terminal is started.

When the voice terminal is started, the voice terminal may need to play voice such as welcome, and therefore the second MCU needs to communicate with Flash first, and at this time, the voice terminal needs to set the third SPI to a working state through the second MCU and set the SPI of Flash to a working state through Flash. Since Flash can only communicate with one MCU at the same time, the voice terminal also needs to set the second SPI to an idle state through the first MCU, i.e., steps 302 and 303 are performed.

In step 302, the first MCU transmits a fifth command and a sixth command, where the fifth command is used to set the first SPI to the working state, and the sixth command is used to set the second SPI to the idle state.

Since the first MCU may need to communicate with the second MCU, in order to improve the real-time performance and success rate of communication, the voice terminal may set the first SPI to an operating state through the first MCU during initialization.

In step 303, the second MCU sends a seventh command and an eighth command, where the seventh command is used to set the third SPI of the second MCU to the working state, and the eighth command is used to set the fourth SPI to the working state.

Since the second MCU may need to communicate with the first MCU, the second MCU sets the third SPI to an operating state at this time.

In step 304, the second MCU sends a ninth instruction to Flash through the fourth SPI, and the ninth instruction is used to set the SPI of Flash to a working state.

Step 302, step 303 and step 304 may be executed simultaneously, or step 302 may be executed first, step 303 is executed, and step 304 is executed finally, and the order of executing step 302, step 303 and step 304 is not limited in this embodiment.

The descriptions of the states of the first MCU, the second MCU, Flash, and SPI are detailed in the description of the embodiment shown in fig. 1, and are not described herein again.

In step 305, the first MCU sends a first command to the second MCU through the first SPI, where the first command is used to switch the fourth SPI of the second MCU from the operating state to the idle state.

When the first MCU needs to communicate with the Flash, the first MCU sends a first instruction to the second MCU to instruct the second MCU to switch the working state of the fourth SPI into an idle state.

The related technology for changing the SPI from the working state to the idle state is already mature, and is not described in detail in this embodiment.

In step 306, the first MCU sends a second command, where the second command is used to switch the second SPI of the first MCU from the idle state to the working state.

After the second MCU switches the working state of the fourth SPI into the idle state, the second MCU releases SPI resources, at the moment, the first MCU switches the idle state of the second SPI into the working state, and communication with Flash is achieved.

In this embodiment, the data stored in Flash includes at least one of a voice function, a voice recognition library, a voice playing library, recording data, MIDI data, a firmware library, and description information. Wherein the voice function refers to some functions that the first MCU or the second MCU may call for performing voice operation. For example, the voice function may include a play function PlaySound () or a record function wave (). The voice recognition library is a library file containing voice recognition instructions, and the voice recognition instructions are used for instructing the voice terminal to execute corresponding operations. For example, the voice recognition instruction includes a forward instruction, a backward instruction, a left turn instruction, a right turn instruction, a stop instruction, and the like, and when the forward instruction is received by Flash, the voice instruction is controlled to move forward. The voice playing library contains voice data to be played. For example, the voice playing library may include a welcome language when the voice terminal is started, an end language when the voice terminal is turned off, and the like, which is not limited in this embodiment. The recording data includes data obtained by recording. MIDI data is sound effect data. For example, MIDI data are "Duo", "Rui", "Mi", and the like. The firmware library contains drivers such as an operating system and the like. The first MCU and the second MCU can call programs in the firmware library. The description information includes information describing the firmware library, for example, the description information includes a version number, and the like, which is not limited in this embodiment.

In this embodiment, the first MCU and the second MCU may be the same MCU, that is, the first MCU and the second MCU have the same control operation on Flash. At this time, the first MCU may perform a voice operation on Flash. For example, the first MCU controls Flash to play MIDI data, at this time, the first MCU sends a control instruction to Flash, where the control instruction at least includes an identifier of a play function and an identifier of MIDI data to be played, and after receiving the control instruction, Flash calls the play function according to the identifier of the play function and plays MIDI data indicated by the identifier of MIDI data using the play function. Alternatively, the first and second electrodes may be,

the first MCU is a master MCU, and the second MCU is a slave MCU; the master MCU is used for updating data in the Flash, and the slave MCU is used for executing voice operation on the Flash. For example, the first MCU updates the operating system in Flash, at this time, the first MCU sends update data to Flash, and Flash updates the operating system in the firmware library and version information in the description information according to the update data.

When the first MCU is a master MCU and the second MCU is a slave MCU, the running speed of the first MCU is higher than that of the second MCU, so that the data are updated into Flash through the first MCU with high running speed, and the updating efficiency is improved; and executing voice operation on the Flash through the second MCU with low running speed.

In this embodiment, the first MCU may also communicate with other terminals to implement communication between the other terminals and Flash. For example, the first MCU may read data from other terminals, and forward the voice data to Flash, at this time, step 308 is executed; or may read data from Flash and forward the data to another terminal, where step 307 is executed.

In step 307, the first MCU reads the data in the Flash through the second SPI, and forwards the data to other terminals through the UART interface of the first MCU.

The UART interface may transmit data with a communication interface of another terminal in a bluetooth mode, a data line mode, a WiFi (Wireless Fidelity) mode, and the like, which is not limited in this embodiment.

In step 308, the first MCU receives data from other terminals through the UART interface and forwards the data to Flash through the second SPI.

In step 309, after the communication is ended, the first MCU transmits a third command, where the third command is used to switch the second SPI from the working state to the idle state.

In this embodiment, the third command may be the same as the sixth command in step 302, and is used to set the second SPI to the idle state. For example, the third instruction and the sixth instruction are both high or low.

In step 310, the first MCU sends a fourth command to the second MCU through the first SPI, where the fourth command is used to switch the fourth SPI from the idle state to the working state.

In this embodiment, the fourth command may be the same as the eighth command in step 303, and is used to set the state of the fourth SPI to the working state. For example, the fourth instruction and the eighth instruction are both high or low.

After the first MCU is communicated with the Flash, the second MCU possibly needs to be communicated with the Flash, so that the first MCU needs to switch the second SPI of the first MCU into an idle state from a working state. The related technology for changing the SPI from the idle state to the working state is well-established, and is not described in detail in this embodiment.

After first MCU switches second SPI into idle state by operating condition, first MCU has released the SPI resource, and at this moment, first MCU sends the second instruction to fourth SPI through first SPI, and the second instruction is used for instructing second MCU to switch fourth SPI into operating condition by idle state.

And after the second MCU switches the fourth SPI from the idle state to the working state, the second MCU can be connected with the SPI of the Flash through the second SPI of the second MCU, and voice operation is performed on the Flash.

The first MCU is communicated with the Flash through the second SPI, and the first MCU is connected with other terminals through UART interfaces, so that the voice terminal can forward data in the Flash to other terminals through the first MCU, and can also forward data in other terminals to the Flash to update the data in the Flash.
