SoftVGA – AVR VGA Display Generator
Posted February 15, 2012 by Chris
“This project is aimed at generating an VGA monitor (basic 31.5kHz horizontal, 70Hz/400line or 60Hz/480line vertical) compatible video signal, without using an specialised hardware VLSI video generator chip (hardwired limited, not available any more), nor 100s of TTL chips. All is done in software, running as vertical “microcode” on an single Atmel AVR microcontroller chip: an ATmega32, 16MHz, 32k Flash, 2k SRAM, 40pin, 32IOs.”
