Introduction:

PS2 keyboard driver module, use a small microcontroller reads the PC PS2 keyboard key-press information, the values of the key will output by serial or parallel or TWI/IIC (through the short circuit cap/jumper option), for the use of other equipment. In a single chip microcomputer project system, main control MCU does not need to write the keyboard driver, as this module reads the key information directly and is very convenient.

Working principle:

PS2 keyboard driver module uses a piece of programmed code of MCU as the controller, to read the state of PS2 keyboard keys. When the keyboard is pressed, the LED lights flashing on the PS2 keyboard driver module, at the same time through serial communication and parallel I/O port or TWI/IIC (through the short circuit cap option), key codes will be output. For example, Press 'A' key, serial port output data 0x1C, parallel I/O port output 0x1C through D7-D0. The output scan code can refer to the back of the key pressed. Pop-up output. In addition, two sets of buttons, TTL output when there is no buttons to press the '0', and have a button to press the output '1', after the button pop-up restore '0' (each key on keyboard effectively. In addition to pause/break key. Serial, parallel, TWI/IIC can work at the same time. If there is no connection from the machine on the IIC/TWI bus, please remove short-circuit cap module above, otherwise, the module will not be able to work properly.

Note:

TWI/IIC address is 4. Modules for the host. Do not use the TWI/IIC should be 'IIC/TWI enable' Short circuit cap to remove, otherwise the module will not be able to work properly. UART Baud rate: 19200
