Design method for switching use of multipath PS/2 keyboard and mouse device

Abstract

The invention discloses a design method for switching use of a multipath PS / 2 keyboard and a mouse device, and relates to the field of management of computer input devices. According to the method, a PS / 2 interface switch module is connected among the multipath PS / 2 interface keyboard, a mouse and a computer PS / 2 interface in series; the PS / 2 interface switch module comprises an MCU serving as a core and a driving function circuit of PS / 2 signals, wherein the devices of the driving function circuit of the PS / 2 signals include a PS / 2 driving circuit and a PS / 2 driving circuit of a host computer; after the PS / 2 interface switch module is powered on, the PS / 2 interface switch module completes the initialization procedure of the PS / 2 interface of a computer end during the startup of the host computer, the initialization is automatically completed by plugging the PS / 2 keyboard and mouse, and PS / 2 data communication among the keyboard, the mouse device and the host computer in a current channel is conducted according to a switch status.

Description

technical field [0001] The invention discloses a design method for switchable use of keyboard and mouse devices, and relates to the field of computer input device management; in particular, it is a design method for switchable use of multiple PS / 2 keyboard and mouse devices. Background technique [0002] Generally, keyboards with six-pin mini-DIN connectors are called PS / 2 keyboards. With the continuous improvement of computer performance and application level, more and more work tasks can be performed by a single computer at the same time, and even multiple work tasks can no longer be processed and controlled by individuals, and sometimes special task instructions of a stand-alone computer system require Workers with different roles issue orders together, and work controllers with multiple seats are required to jointly operate a computer host. In this case, it is necessary to set up multiple sets of input devices for the host computer, and the present invention provides a ...
