I am currently trying to get this Code running on my Raspi, but I cannot get a PWM Signal high enough, to turn on the LEDs. I meassured the output I get from several PWM Pins or SPI Pins. They are always anywhere close to 50mV. Is this what they are supposted to do? I am trying this Library with WS2815 Model LEDs, which should not do quite the Difference.

not sure if this is your issue, but you need a level shifter to run the pixels on a raspberry pi, they expect 5v signal, and 3.3v is not enough for some strips.
