D-Pad data compression? Answered
So, I'm working on a small, simple, and yet very inefficient game console using multiple ATmega328 chips. Basically, I'm trying to compress the controller data into as few wires as possible using an ATmega. Hopefully using something along the lines of http://pinouts.ru/Game/genesiscontroller_pinout.shtml. Anyone have any idea how to do this? I can handle coding, it's just the actual logic of it.
