    Hello Jarda,

    Thank you for your quick response!

    According to the data sheet, transmitting one bit of information to the WS2811 takes about 2.5 us in slow mode. Which translates to a frequency of 400 kHz. Lowering the transmission speed sadly isn’t an option because the IC can’t read data that’s being sent at a lower frequency. So I guess I’ll have to use the pin header…

    As for the PWM issue, just now I put a 1kOhm resistor in parallel to my multimeter, loaded the Fade program from yesterday and I now get correct readings froom 0.2V to 12.3V! So that’s solved. Thanks a lot!
