NeoPixel CircuitPython DMA Library

by dunkmann00 on Sat Oct 05, 2019 10:11 pm

I am looking to get a project started using the itsy bitsy M0 and some NeoPixels. I'm also interested in making it in CircuitPython. I don't see a NeoPixel DMA library for CircuitPython and was wondering if there are any plans to make one?

Is there a reason you need DMA? For the Itsy, you can use the main CP NeoPixel library:

I'm not exactly sure if I do....I wanted to drive the 24 RGBW NeoPixel Ring and also play audio from a wav file out of the DAC. Do you think that would work fine if I used the regular library?

In general it should. But if you want to have the NeoPixels change while music is playing, that can get trickier. But start simple and see how far you can get.

Yea I was going to have them changing throughout. I'll just have to test it and see. Thanks.
