PS/2 to RS-232 interface

This project is a Microchip PIC microcontroller with an RS232 serial interface on one side and an PS/2 (keyboard or mouse) interface on the other. The PS/2 interface uses bit-banging on a 12F683 device.

The PS/2 interface operates as a host and initialises the keyboard or mouse before going into a never-ending loop of reading the data and sending it to the RS232 interface. (via)
