Hello. I am looking for some guidance on balancing the color across multiple LED strips (I am new to this). I have 2 strips that I purchased at 2 different times (within 6 months of each other) from the same vendor and are the same brand (Alitov). Both are WS2812B strips with 150 LEDs. When testing solid white, they put out different colors of white. One has a bit of a blue tint to it.
When set to solid red, blue or green, they seem to be the same. Lighter colors is where I see the problem. I see the same whether they are daisy-chained together or powered and signalled independently. So from what I can tell, there is a slight difference in the way each strip is processing white as a color.
Is there a way for me to balance these together thru code or physically in the strip? Thanks in advance for any help
Yes, you can probably balance it a bit in code. If each strip is hooked to a separate data pin it will be easier and color correction can be done by adding .setCorrection(some correction values) on the end of the addLeds line so it looks like this:
This (extreme) example would reduce green by 50%, and blue by 25%.
If the strips are hooked together and only on one pin you might need to roll your own color correct function to that would only run on the pixel range covering one of the strips. You would then run this right before running http://FastLED.show().
