Arduino VGA Output Using Timer Interrupts
Posted September 20, 2012 by Chris
“In this article we’ll explore how to output VGA signals from an Arduino UNO by using the timer interrupt to keep output in sync with the exact timing required by the VGA protocol. The end result will be a very empty ‘main’ loop in our software and a lot of interrupt code that handles everything else. The Arduino is only running at 16 MHz so doing VGA with interrupts on it is really pushing the limits!”
