A PS/2 Keyer: Using Keyer Paddles to Emulate a PS/2 Keyboard and Mouse

摘要

In the past several years, I became interested in learning how to program Microchip PIC microcontrollers and I began to look for an interesting project. As an experienced C programmer, I knew nothing about PIC microcontroller programming. My criteria for the project was that it needed to have a well defined input, a well defined output, and the circuit needed to consist solely of a PIC microcontroller with some LEDs. And, importantly, it needed to be written in C.
