Adafruit 16-Channel 12-bit PWM/Servo HAT

by DLH_OldGuy on Tue Apr 23, 2019 7:33 pm

Once I have run a program on this is there a command or a program that I can run to reset the board. Currently the channels continue to perform the last commands given them. The only other alternative is to power down the R Pi.

Any suggestions?

Regards

That's normal. The PCA9685 keeps generating whatever PWM duty cycle you told it, until you tell it to do another.

You can make a quick script that runs through all the channels and sets their duty cycles to zero. That should clean up after any program that doesn't zero the channels by itself.
