Hi,I have a system which runs Linux, and has GPIO pins available. I want to use it to program an ATmega168/328 chip.
If my system has a C library with the following Arduino style functions available to it:
pinMode () digitalWrite () digitalRead () along with pullUpDnControl () which can enable pull-ups, pull-downs or tristate...... then given 4 spare GPIO pins, how hard will it be to knock up a new bit banging programmer module for avrdude?
Accomplished C programmer here and I'm looking at the source, but really not sure where to start...
Thanks, Gordon
