Request: RGBW Mode about mclighting HOT 12 CLOSED

Just to update this, McLightning works with RGBW Pixels but without using the white-channel.

Simply change the pixel type in the WS2812FX init from

WS2812FX strip = WS2812FX(NUMLEDS, PIN, NEO_GRB + NEO_KHZ800);

to

WS2812FX strip = WS2812FX(NUMLEDS, PIN, NEO_GRBW + NEO_KHZ800);

Have look here:

Unfortunately it‘s a separate effort, but I still hope that it will be integrated into the „master“ at some point in time.

I've been looking at that one, but as you say it's a separate effort - which isn't necessarily bad, but I would have preferred a joint effort :)

I think this may be possible as the Adafruit library seems to support these, at least in RGB mode. I don't know how the W can be adressed. But maybe you can give it a try if you have a SK6812 at hand.

As you talk to RGB with each bit, you have to talk to the 4th bit too which is seperate white to rgb.

I have tested it over Homebridge with Homekit and the 4th bit, the W was lighten on. But your Arduino and index.htm can not handle with it, the brightness lower or higher or on off of the 4th bit. I did not study your complete code, just uploaded and tested ;P Need time to check it and give a test but could take time as I am not free.

Edit: Shortly found this here

Arduino Sketch for RGBW: https://github.com/adafruit/Adafruit_NeoPixel/blob/master/examples/RGBWstrandtest/RGBWstrandtest.ino

Adafruit_NeoPixel.h
https://github.com/adafruit/Adafruit_NeoPixel/blob/master/Adafruit_NeoPixel.h

void loop() {
  // Some example procedures showing how to display to the pixels:
  colorWipe(strip.Color(255, 0, 0), 50); // Red
  colorWipe(strip.Color(0, 255, 0), 50); // Green
  colorWipe(strip.Color(0, 0, 255), 50); // Blue
  colorWipe(strip.Color(0, 0, 0, 255), 50); // White

  whiteOverRainbow(20,75,5);  

  pulseWhite(5); 

  // fullWhite();
  // delay(2000);
  rainbowFade2White(3,3,1);

Hi Tobias,
any plans to implement this?
I would be really interested for having a combined "normal" lamp with RGB options for the kids rooms
Thanks, ESP boards are on the way...;)

HI @martinschki,

there is already a fork of McLighting that provides support for RGBW. Unfortunately it's not so easy to integrate into the main code, but you could give it a try: #94

Best regards

Any news on this? I think McLighthing works really well, but lacking support for RGBW is a real bummer.

Support for RGBW is the difference between it being a fun project, and then being actually useful in a home.

Where do I find this file that needs the change? Also, has official W support ever been fully integrated?

from mclighting.

@VeniceNerd The changes from the develop branch were merged to the main branch a bit accidentially. That messed up everything. So you should now have all RGBW changes also in the main project, but they're not complete now and not really tested so far. I think I'll have to do a bit housekeeping to clean up everything.
The mentioned lines can be found in McLighting.ino

Did anything happen in the meantime in the direction of RGBW integration or housekeeping?
I think SK6812 RGBW will get more and more important and it would be great if it could be supported.

Just use this fork. https://github.com/FabLab-Luenen/McLighting
