• Thx for taking the time. Most appreciated if you could try accessing the first LED in the string.

    The data sheet did state GRB, which was my experience.

    But putting that aside; the real issue was the first two bytes in a data array being ignored. So in short, on pin A7 with SPI1, I can only set the first LED to intensities of blue (being that the G and R bytes were ignored). All other LEDs were fine (LED 2, 3, etc.)

    On pin B15 with SPI2, everything was fine. But I need the SD; and the fun part here is accessing the SD generates an inadvertent light show. Lol.

    It would be awesome if you could share you findings / code samples when you have a moment (with some WS2812B's in your possession).

    Thank you!
