Pretty new to the Pi game, I have a PI 3 setup with a UPS PIco, working 100%.
I stacked on a RGB LED Hat, the WaveShare half hat version and am trying to get the LEDs, to trigger, however nothing happens.
I have checked using gpio readall that pin 18 (which i understand is the comms pin for the Hat) is set to ALT5 (PWM, which is how I understand the Hat get's its comms)
I have run the test/demo scripts that come with the WIki as well as forcing Pin 18 to high, still no luck.
When I turn the Pi on with the Hat in, one or two of the LEDs briefly flash, which leads me to assume the Hat is ok?
Any ideas of how I couldg get it working or anything else I could test?
