Working with the TCL p9813 string and FastLED,

Working with the TCL p9813 string and FastLED, I find that the white on these guys is distinctly bluish when I run the white dot sketch. All of the pure RGB colors look fine. I tried adding a .setCorrection(P9813) and got a very dim pure blue. Can someone point me toward a suitable color correction for these?

Try setCorrection( TypicalLEDStrip);

Other than that, you can adjust it yourself:

setCorrection( CRGB( red, grn, blu))
Where the values range from 255 (full brightness) to 0 (totally off).

I usually start around CRGB( 255, 170, 240);

OK, thanks Mark.

Also - before you do too much adjusting in here, run RGB calibrate and make sure that you have the right RGB order set for your leds - otherwise things might come out … weird :slight_smile:

Did those things. The RGB order is correct, and the white is now whiter. But in order to make them work I had to find an example in which there was an addLeds specification for the P9813…and I notice that it does not include specification of the DATA__PIN, as the others do. How does that work?

If you’re using the hardware spi you don’t need to bother with specifying the clock and data pins.
