ATiny does 170×240 VGA with 8 Colors
https://www.electronics-lab.com/atiny-does-170x240-vga-with-8-colors/
AtomicZombie @ avrfreaks.net used an ATtiny85 ATMEL microcontroller to produce a 170×240 VGA signal and also send audio along with video. The original plan was to just bit bang some mono VGA and do up a Pong or Tetris game, but things went MUCH MUCH further than I ever thought possible, so over the next few […]
