A while back, I posted up a quick and dirty “el cheapo” method of getting started programming the Atmel AVR series chips: Ghetto Programmer (version 1.0) Since then, I’ve vamped, re-vamped, and otherwise improved my setup. Thought it’d be nice to document it. The goal was to get a flexible, compact, portable, use-anywhere, AVR-based microcontroller
