Is there a way to force WS2812B LEDs to use 400kHz data rate (or tell FastLED to do so) ?
I have a project with a Polar heart rate monitor receiver and the LEDs seem to interfere very much on it.

I have tried using the WS2811_400 controller (on FastLED2.1), but it doesn’t work with my WS2812B (Neopixel ring) LEDs. Any ideas?

No, there isn’t that I’m aware of. (The WS2811 choses between fast/slow data rate based on, I believe, resistance on a particular pin - so it’s done at the hardware level).

:confused: ok, thanks for the heads up. I will try putting the receiver as far away from the LED data wire as possible and try again.
