Larry Bank Posted March 11, 2018 Share Posted March 11, 2018 I just released a simple library for the MAX7219 LED matrix controller. It allows controlling any number of cascaded controllers in a very simple way. I tested it on an Orange Pi Lite. Even though it says it needs 5V, I ran the board @ 3.3v, it worked fine and didn't require any 3.3v->5v level converters. Here's the code: https://github.com/bitbank2/MAX7219 And a video of it in action: https://photos.app.goo.gl/iO66bsy6Wk13lT1y2 1 Link to comment Share on other sites More sharing options...
