Accompanying drawing 2 is process flow diagrams that keyboard and mouse of the present invention is realized hot-plugging technology.
Mark in the accompanying drawing is represented respectively:
1, interface module, 2, the data transmit-receive unit, 3, data processing unit.
Embodiment
Below in conjunction with accompanying drawing the implementation method of the hot-swappable use of a kind of PS2 interface keyboard mouse provided by the present invention is done following the detailed description.
Be to realize the hot-swappable use of PS2 interface keyboard mouse, a great problem that at first will solve be interface module 1 how accurately reception how invalid data is accurately discerned and is filtered from the valid data of main frame or keyboard, mouse.
For addressing the above problem; The implementation method of the hot-swappable use of a kind of PS2 interface keyboard mouse is provided at present; Like accompanying drawing 1, shown in Figure 2; Its structure comprises the PS2 interface module 1 of hot plug, is respectively arranged with data transmit-receive unit 2, data processing unit 3 in this interface module 1, adopts the I2C protocol bus to communicate between above-mentioned data transmit-receive unit 2, the data processing unit 3; The transmitting-receiving of the two-way PS2 data of initial phase is accomplished in data transmit-receive unit 2, the control that data processing unit 3 is accomplished transceive data and data channel.
Concrete implementation method is following: at first with PS2 interface keyboard, the mouse signal input end signal as interface module 1; The output terminal of interface module 1 is connected to the PS2 port of main frame keyboard, mouse; Carry out the initialization of keyboard, mouse initialization and main frame then respectively separately: at first when computer starting; Interface module 1 simulation PS2 interface mouse, keyboard are accomplished the initialization of host side PS2 mouth; When main frame was not accomplished initialization, interface module 1 inquiry also received the main frame initialization command and sends handshake, accomplishes the main frame initialization; Interface module 1 analog computer start-up course is accomplished the initialization of keyboard, mouse; When the initialization of keyboard, mouse imperfect tense; The initialization command of interface module 1 inquiry and reception keyboard, mouse sends the initialization that corresponding configuration data is accomplished mouse-keyboard with this initialization command then; After main frame was accomplished initialization, when the keyboard initialization was accomplished, main frame and keyboard were connected to the keyboard data passage, and when the mouse initialization was accomplished, main frame and mouse were connected to the mouse data passage.
Above-mentioned PS2 interface module 1 is inserted on the computing machine PS2 interface.
