White value in Blue color on Rpi3 with GRBW strip #505

Open BinaryBrain opened 1 year ago

BinaryBrain commented 1 year ago

When asking my LED strip (SK6812_STRIP_GRBW) on my Raspberry Pi 3 Model B to turn on blue LEDs only, white LEDs are also turned on. The Red and Green are perfect, but the Blue seems to be lighter than it should be because White is ON as well. I don't think it is a hardware issue because it is working with some other libs, or when I trick the lib and use a simple RGB profile.

Am I the only one with this issue or is it something more common?
