  • @Gordon, could you please clarify one moment for me? Espruino Neopixel API reference says the following:

    If I remove my transistor, connect STM32's pin directly to Neopixels's data and add a pull-up resistor to 5V there, then set this pin to af_opendrain mode and run
    require("neopixel").write(B5, [255, 255, 255]);
    It should work, right?

    I have tried this and it didn't work. I begin to suspect that I accidentally burned the LEDs...
