Brief 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, for the use of other equipment. In a single chip microcomputer project system, main control MCU does not need to write the keyboard driver, read the key information directly, very convenient. 2. Working principle PS2 keyboard driver module USES a piece of programed 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 ,tht value of keys will be output. For example, Press "A" key,serial port output data 0x1c, parallel I/o port output 0x1c by D7-D0. The output scan code can refer to the back of the content. 3. Performance parameter 1>. working voltage:DC5V; 2>. Key information is sent out by serial(Baud rate 19200) and parallel 3>. corresponding speed; 4>. apply to PC PS2 keyboard. 5>.Module size: 35.5mm(length)*33.5mm(width)*18mm(high) 4. Module instructions 1>. Interface definition RXD:Receive Data,connect to TXD of MCU; TXD:Transmit Datar,connect to RXD of MCU; GND:connect to GND; +5v:connect to VCC(5V). D0-D7:Parallel communication data port; 2>. Serial interface circuit 3>. P arallel interface circuit 5.
