ArduinoVideo

A small project where I try to generate composite video from an arduino Mega

I started this project without knowing neither arduino or how video signal works... So it may have hundreds of flaws.

What I have achieved is a 80x64 black and white (no gray) resolution. with this I got, still image, scrolling text (3 screens) and 2 frame animation.

Currently working on how to make it work with interrupts instead of a loop with counted-ish cycles.

My code is really messy as I never intended to be seen by anyone.
