Product Description

PS2 Keyboard Driver Module Serial Port Transmission Module

PS2 keyboard driver module
1. Function:
PS2 protocol conversion to twin / IIC, UART, parallel interface
Increase key state detection. Wide range of applications.
2. application:
Robots, electronic products, and the like. Suitable for 101/102/104-key keyboard
3. brief introduction
PS2 keyboard driver module, using a small microcontroller reads PC PS2 keyboard key information, the key value through a serial or parallel output, the use of other equipment. SCM system in the project, the main control MCU keyboard driver does not need to write, to read the key information directly, very convenient.
PS2 keyboard driver module, using a small microcontroller reads PC PS2 keyboard key information, the key value output or twin / IIC, use (by shorting cap option) to other devices through a serial or parallel. SCM system in the project, the main control MCU keyboard driver does not need to write, to read the key information directly, very convenient.
4. working principle
PS2 keyboard driver module uses a microcontroller as controller programed Code, read status PS2 keyboard keys. When the keyboard is pressed, LED lights flashing PS2 keyboard driver module, through serial communication and parallel I / O port or twin / IIC, the key will be output (by shorting cap option).
For example, press “”, 0 x1c serial output data, the parallel I / o port output 0 x1c D7-D0. Output scan code can reference the contents of the back.
Pop-up output. In addition, two buttons, TTL output when no key is pressed “0”, and output after a button press “1” button to pop up the recovery of “0” (valid for each key on the keyboard. In addition to pause / stop button.
Serial, parallel, twin / IIC can work simultaneously. If the machine is not connected to the IIC bus / twin, remove the shorting cap on top of the module. Otherwise, the module will not work properly.
5. Precautions:
1. Twins / IIC address is four. Host module.
2. Do not use a twin / IIC should 17IIC / twins make 17 shorting cap removed. Otherwi se module will not work
3. * UART baud rate: 19200
6. Performance parameters
1>. Operating voltage: DC5V;
2>. The key information is sent via the serial (19200) and parallel
3>. The appropriate speed;
4>. Suitable for PC PS2 keyboard.
5>. Module size: 39.1 mm (L) * 31.2 mm (width) * 18 mm (H)
