RGBW colour palletes…
So i know fast LED does not support rgbw yet, but i wanted to open up the floor and ask…HOW does one translate a standard rgb value to rgbw pixels??
I can generate a rainbow on the fly as per pic with rgb, but how does the W relate to all the colours?
Any sugestions welcome! Ill happyli make the code public.
Have you tried this?
@Jeremy_Spencer thanyou!!! Im gona delve into that
@Jeremy_Spencer So I got it to work (using my Custom SPI Neopixel lib on an ESP8266) https://www.instagram.com/p/BZGV98XlaQf/ but iI’m not 100% sure what that code you suggested is really supposed to do. Will think this through. The basic driver is here https://github.com/leonyuhanov/SK6812viaSPI/tree/master/SK6812_RGBW_SPI
Interesting paper about this topic with a low computational cost algorithm for rgb to rgbw conversion with great accuracy.
