Hello, I need a LED strip where I can control the LEDs individually, but also have more than 3 color channels like with e.g. WS2812 or the 4 with SK6812. I would like to control at least 5 channels (RGB + warm white + cold white) but in the best case I would want a protocol that can control even more channels (RGB + warm white + cold white + amber + lime + deep blue + ...). Is there already some protocol that has the ability to do that or what would be the easiest/best way to do that?
You could just use the chip inside those Neopixels and connect like two or three of them per lamp, giving you 6 or 9 channels. The protocol of any RGB lamp just transfers (usually 8-bit) brightness values, not a color, so youc ould connect any lamp you like.
Hey, yes, but are there LED strips that have that functionality? I would want to just have a reel like a normal LED strip, but have more control channels for more colors.
I'd say no. There are RGBW LEDs with one white, and there are Strips with those. Then you find Strips with CW and WW LEDs, but those lack RGB. I've never seen strips with those weird colors you want, even normal LEDs are hard to get, so you may not even find lamps with that mixture. Commercially available RGB/CW/WW lamps have separate LEDs for RGB, C and W, and i guess there's a reason for this... ;)
There is the ws2811 led driver chip. You can attach any led you like and cascade as many as you need. Otherwise I see no other solution beside a discrete build. Take a small microcontroller and an led driver like the tlc59116 and create your own protocol.
