Hello,

Currently trying to use the Madmapper tutorial for interfacing with WS2812 leds though a Arduino/Teensy, right now sticking with just 30 leds and an Arduino Uno, while running a Windows 10 machine.

I've managed to get it communicating but with many errors. Static images don't work at all, and moving the fixture or placing an animated material leads to glitchy behavior, like random pixels firing or not, the leds refreshing with no fixed periodicity, and a third of the strip being completely ignored even if it worked with the embeded testing method.

Is there something I am missing about the implementation, is it inherently buggy or is there something about using the Arduino UNO that simply isn't enough despite the smaller scale?

Did you use the serial one line .ino?
Change the settings for the correct led stripWS2812 (check if it's not a B rev) (undo the comment in the arduino code)
Make sure the settings in madmapper are correct with RGB or GBR etc.

I just did it with WS2812b and works like a charm.

Personnalty I never get it to work properly with an arduino. Only with Teensy. But it seems possible depending on the USB chipset. If you really want to use it, just get a teensy. Or use a good pixel controller hardware for a professional setup.
