Curious if anyone has used a Particle Electron with FastLED and WS2811 LEDs?

I can’t get the Electron to control the LEDs. Not sure if there is perhaps a conflict w/ the FastLED library and something in the Electron (running offline)? I’ve previously used WS2812 LEDs w/ the Electron, but can’t get my WS2811 working (confirmed working with other controllers).

Maybe there are other issues/concerns I’m not aware of?

Thanks!

I’ve not heard of that microcontroller before. What chip does it use?

Just guessing, but probably an interrupt issue? See: https://github.com/FastLED/FastLED/wiki/Interrupt-problems

The Particle devices use a lot of interrupts inherently, behind the scenes, to manage their networking/cloud comms.

Strangely I had it working w/ WS2812 strips before . . . I don’t actually need the cellular functions for the current project so I’m probably going to change to a “simpler” board (Trinket, Teensy, etc.). Cheers!
