Hey Folks,
Has anyone used DotStar and NeoPixel LEDs with Processing and Raspberry Pi? It should be possible since Processing can access the GPIO but there’s not a library that I can find. Thanks for the help!
I found this neo pi tuto
and the gpio reference
Neopixel need a very time accurate signal, that the Pi can’t provide over its GIPIOs.
If you want to use Processing with Neopixel (and the Pi), I can recommend a Driverboard called FadeCandy by Micah Scott. It comes with a nice Processing Library, a lot of examples and good documentation.
The FadeCandy Library takes really good care about things like color dithering so the LEDs look even nicer.
I made good experience using FadeCandy with a Raspberry 2B and WS2812B (Neopixel).
