Abstract

PURPOSE:To transmit effectively information to a host device by making it possible that a mouse controller changes the time interval of transmission to the host device on a basis of the order from the host device. CONSTITUTION:This system consists of a host device 1, a mouse controller 2, a mouse 3, a control circuit 4, a receiving circuit 5, a transmitting circuit 6, a mouse counter circuit 7, and a AND circuit 8, and the circuit 7 extracts position information of the mouse. The time interval of transmission of mouse information to the host device 1 can be changed within the range from, for example, 10-20ms in accordance with the order from the host device 1. Even after the time interval of transmission of mouse information is set, information is not transmitted if preceding transmitted information is not changed. It is selected whether mouse information should be generated or not in accordance with the order from the host device 1.

Description

Detailed Description of the Invention [Summary] In a data processing device having a mouse control device that transmits information including position information from a mouse to a higher-level device, the mouse control device transmits information including position information from a mouse to a higher-level device based on an order from the higher-level device. It is disclosed that the time interval for transmitting data to a device can be changed to make the transmission to a host device more effective.

[Industrial application field]

The present invention provides a mouse control method, in particular, a mouse that allows mouse information to be notified to a host device to change the time interval at which the notification is performed depending on the order, thereby making the mouse information received by the host device more effective. It is related to the control method.

[Conventional technology]

Conventionally, a configuration has been adopted in which mouse information is notified to a host device, and the following means have been adopted. That is.

i) Mouse information sent from the mouse (switch or
, Y data, etc.) is processed by the mouse control device and sent to the host device at regular intervals.

ii) The software of the host device takes in the mouse information through 2-interrupt processing each time it is notified.

iii) Furthermore, the above notification interval for mouse information is set to a value as short as possible in order to increase tracking speed.
Conventionally, this value was fixed.

[Problem that the invention seeks to solve]

In the conventional case described above, regardless of whether the mouse information is necessary or not, the software of the host device must take in the mouse information that has been notified. Therefore, when executing several jobs, these jobs will be executed in between importing mouse information, which may slow down the job execution speed or cause problems such as overruns. there were.

[Means for solving problems]

The present invention is intended to solve the above problems.

FIG. 1 shows a block diagram of the principle of the present invention. Code 1 in the diagram
is a host device, 2 is a mouse control device, 3 is a mouse, 4 is a control circuit, 5 is a reception circuit, 6 is a transmission circuit, 7 is a mouse counter circuit that extracts mouse position information,
8 represents an AND circuit.

[Effect]

The illustrated control circuit has a function of performing primary operations.

(A) In response to an order from the host device 1, the time interval for transmitting mouse information to the host device 1 can be changed, for example, from 10+am intervals to 20 m5 intervals.

(B) Although the time interval for transmitting the mouse information to the host device 1 is set as in paragraph (A) above, there is no change in the previously transmitted mouse information even after the setting is made. If so, do not send.

(C) It is possible to select whether or not to generate mouse information in response to an order from the host device 1.

〔Example〕

FIG. 2 shows the configuration of an embodiment of the main part of the control circuit according to the present invention. Reference numeral 4 in the figure corresponds to FIG. 1, 9 is an order register, and 10 is a decoder.

11 is a mouse enable flip-flop.

12 is a preset counter, and 13 is a clock source.

Reference numeral 14 represents a transmission processing section, 15 a change detection section, 16 a transmission information creation section, and 17 an AND circuit.

In an order from host device 1, the first byte of the order code is the value X"22" and the second byte is (
In the case of direct X "30" to
“When 22° is decoded, the value of the second byte is X”
30° to X “3F” is preset in the preset counter 12. Then, when the counter 12 finishes counting the value corresponding to the value X "30°" to X "3F", the AND circuit 17 is enabled.

9 Although not shown, the preset counter 12
is preset to its original value again. Therefore, mouse information is sent to the host device via the transmitting circuit 6 at a predetermined period when the AND circuit 17 is turned on. Note that the AND circuit 17 is turned on on condition that the "change" signal from the change detection section 15 shown in FIG. 9 is the logic rlJ. The mouse information sent to the transmission processing section 14 via the AND circuit 8 shown in FIG.
At step 5, the presence or absence of a change is checked. Further, the transmission information creation section 16 performs a predetermined format change.

In an order from the host device 1, if the first byte of the order code has the value X°21°, the flip-flop 11 is reset.

The mouse enable signal becomes logic "0", the AND circuit 8 shown in FIG. 1 is turned off, and no mouse information is sent from the mouse side. That is, in this case,
Since the change detection unit 15 does not generate "change", no transmission to the host device 1 is performed.

In an order from the host device 1, if the first byte of the order code has the value X "20", the flip-flop 11 is set and the mouse enable signal becomes logic "1". As a result, the AND circuit 8 shown in FIG. 1 is turned on.

Mouse information from the mouse side is guided to the transmission processing corresponding section 14.

〔Effect of the invention〕

As described above, according to the two aspects of the present invention, the mouse information received by the host device is only more effective information, and the processing amount of the software of the host device is reduced.
