These are the files needed to run the AVR that outputs to some GPIO port

I included my avrdude.conf for easy building. It has a few neat tidbits that the stock one does not.

On a Debian system you need:
avrdude
gcc-avr
Probably some obscure -dev package I forgot.

To compile, make sure you have the correct fuse bits set in the makefile, as well as the correct model for the AVR, as well as a USBASP or other relevant programmer.

Compile:
make
sudo make program
