• I just tried to test a recently bought Neopixel RGB LED matrix. Since first experiments with an obniz board could test up to 85 LEDs only (but they were working fine), I though it might be a good idea to reactivate a MDBT42Q (after a firmware update to 2v10).

    A very first attempt

    let Neopixel = require("neopixel")
    Neopixel.write(D22, [255,0,0])
    

    showed a green(!) pixel - and

    let Neopixel = require("neopixel")
    Neopixel.write(D22, [0,255,0])
    

    turned it red(!) - blue seems to be fine.

    Are "R" and "G" just switched? That would sound strange...
