So I have a functioning RPI3 running apa102 LEDs but the video capture is leading to a number of issues so I am trying a better capture device but it only works on RPI4 due to USB3.0. Anyway I got everything installed and imported my settings from the RPI3. The RPI3 controls the LEDs fine, but the RPI4 does nothing. Looking at GPIO they have the same pinouts as far as I can tell. Anything that I am missing between the 3 to 4.
Thanks
