  • Looks nice! I guess it doesn't actually add much to the cost vs. a WS2812B if you're using LEDs on a PCB. I guess the LED strings with wires will still have a slight premium though.

    What's the power-on state? I know I bought a bunch of APA104s (WS2812B clones) and the power on state was full blue, which really sucked for pretty much everything - the under counter lights in my kitchen have this annoying 100ms blue flash when turned on now!

    By the way, you can change:

    this.spi.send([0,0,0,0]);
        this.spi.send(this.fbuf);
        this.spi.send([0xFF,0xFF,0xFF,0xFF]);
    

    to:

    this.spi.write(0,0,0,0,this.fbuf,0xFF,0x­FF,0xFF,0xFF);
    

    SPI.write doesn't try and receive any data, so it doesn't allocate an array for the data it gets back - it should also be a bit faster.
