This code is a modified version of HIDKeys.2007-03-29 that can type "Hello, world". It is the same code that is used on my YouTube video USB Keyboard using ATmega8.

I wrote this as a hack, as a proof-of-concept, just to see if it would work.

If you want to start playing with ATmega8 or AVR microcontrollers, take a look at my blog: First contact with ATmega8 microcontroller
