Working Paul McWhorter’s series with the AI fusion hat. While working in PWMs out, I get the following error: OSError: Fusion HAT not connected, check if Fusion Hat is powered on. The line of python which triggers it is: redLED= PWM(redPin). RGB LED is ON all the time (all three colors)…have to remove physical connection to turn off, even when Hat/Pi are shut down. I was able to use digital out pins successfully. All lights are ‘on’ on the hat, successfully zero’d servos, …seems to function otherwise so far as I have ran it. Any suggestions? Thanks!
