AT Keyboard library for avrgcc

AT-Keyboard library

Taken from ATMEL Application Note AVR313

A standard AT (ps2 ir DIN plug) Keyboard can simply be connected to an AVR microcontroller using only 2 I/O wires as shown below. One wire has to be an INT line (INT0 or INT1) the other pin can be configured by defining KEYB_DATA_PIN in atkeyb.h

If you get some compile errors complaining about undeclared constants, you might have to change the names od the interrupt registers.

Please contact me if you don't get your application running! to use the keyboard library with an other AVR c
