I am stuck with a couple 100 of of RGB-W Leds of the following kind:

I tried a bit driving the whole thing using an ESP32 but I got into all kind of flickering issues, ESP32 just was not real time enough for me I guess.

I was hoping to use a teensy 3.2 with the adapter board and the OctoWS2811 library, but then it hit me that I have RGBW Leds.

Anyone tried to use that library with RGBW Leds?

(I have previously used the popular FastLed library as well but it has the same issue, it does not support RGBW. According to the FastLED developer it is being worked on, but that has been going on for years now)
