Welcome to the - AVGA - Homepage
The AVGA project - open source AVR based color video game development platform for single chip game console.
This platform enables you to code a color, high resolution, smooth video game, like Super Mario Bros or Commander Keen on a mega AVR. All video processing is done by software in background using interrupts, with no external active components. You only need to connect the AVR to a RGB monitor. It is designed to occupy very little flash and to return the CPU to main program whenever it is just possible. Everything can be customized to meet your project needs.
Clipping demo, ATMega168 @ 25 MHz
VGA 112x112x4bpp
Super Mario clone, ATMega168 @ 20 MHz
PAL 192x144x4bpp
