sk6812 rgbw
« on: June 12, 2017, 05:24:00 PM »
I am having a hard time with this one. I have some sk6812 rgbw led that i put in a light bar and am having a very hard time finding a controller that will do what i want. I do have a sp105e controller hooked up and working ok but i need to control them like i do my christmas lights. Dose anyone know of a controller that will do this?

Looking at a few spec sheets, the sk6812 is related to the ws2812. 

In xLights, you can define a string of pixels as RGBW (like the sk6812)

If so, I wouldn't be surprised if it worked as a ws2811 pixel type choice in most controllers.
It is 3-wire, so trying it would not harm anything.

ps, if it does harm anything, I live in a foreign country and you'll never find me.

xlights does not support RGBW pixels.  The RGBW type is meant for support of 4 channel "superstrings".  I've asked about adding RGBW pixel support, but there did not appear to be any interest from developers or other users.

It might be possible to use custom models in order to configure the RGB portion of the RGBW pixel string, and another custom model for the W channels.  In this way pixel effects could be applied to the RGB models and render correctly.  I want to try this eventually, but my roofline pixel replacement that i wanted to do this season has been put off until next year.

Any luck with controlling the full potential of these lights?
