WS2811 Usage
-
Any have experience with driving a Ws2811 IC ie used to drive a RGB LED.
Apparently it uses NRZ code which is foreign to me.

Do you mean WS2812 RGB with integrated WS2811 or WS2811 as separate IC? -
@livius Yes i do

@misterlisty
May i ask why? if you have cheap integrated one?
But i do not see the difference if you connect it same you got WS2812 ;-)
And you can work with standard lib -
@livius Thanks, not sure what you mean can work with standard lib? I want to add a RGB to the external of an enclosure so cannot use the builtin one on the module.
How do i work with standard library?

@misterlisty
maybe we do not understand each other ;-)
I do not say about integreated into pycom module (Heart beat LED)
I am talking about WS2812 which is WS2811 IC + LED 5050.In your question is WS2811 not WS2812 and because of this i have asked
Do you mean WS2812 RGB with integrated WS2811 or WS2811 as separate IC?
If you try to drive RGB led(WS2812) strip use existed libs like:

@livius this looks like exactly what i'm looking for, will try it today.

@livius I am using the separate ws2811 ic and i have tried your code and it appears not to work? The datasheets suggest different timings..can you suggest what i need to adjust? https://cdn-shop.adafruit.com/datasheets/WS2811.pdf
