 How early did it was this putting my final touches on the LED glasses front panel This is our circuit Python test code You're seeing this flicker here because it's kind of writing the ring and the matrix at the same time And I'm not really doing a proper double buffering yet But it's just a good demo of showing all the LEDs and then this is my tester My tester, which is an Arduino who know where the little STEM like a connector on the end so it's really fast You can even test these before they get panelized So turning out all the LEDs and then there's actually internal test mode in this chip that I'm going to end up using But for now it's going to be basically like do all the LEDs in each color light up If so that means the LEDs were placed properly and the multiplexer is working so Soon to be in the shop
