RGBW

Hi Brian could this drive RGBW Neopixel tape?

Hi! I did try it out with some RGBW a long while ago. There's the rgbw branch that I made back then: https://github.com/usedbytes/neopixel_i2c/tree/rgbw

To be perfectly honest, I don't remember it so clearly, but if you run into some issues I'll be happy to try and help as best I can!

That's great thanks, What work would be involved in making your code work with the newer?

I actually dropped you a message on your hackaday site.

If you're interested in the i2c part of the project, then it would need to be entirely re-written for that processor, as they have different i2c hardware (and different everything else)

If you're interested in just driving neopixels, then I didn't write that bit, it's from: https://github.com/cpldcpu/light_ws2812
I see there is Cortex-M0 code there, which I suppose it should be possible to get to work on the trinket, but I don't know the details https://github.com/cpldcpu/light_ws2812/tree/master/light_ws2812_ARM
