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!
