PWM wave in pocketbeagle

[Rafael Meyer]

Hello,

I am a beginner in programming and acquired a pocketbeagle card.

 

So far I have just configured the pocketbeagle to communicate with the internet and updated the software. I used a simple code from the internet to test the board's leds but I still don't know how to configure the pins.

I would like to know how to generate a PWM wave with code in python3. 

 Thanks!

Based upon
https://raw.githubusercontent.com/wiki/beagleboard/pocketbeagle/images/PocketBeagle_pinout.png
there are four pins that support PWM output. P1_33 (defaults to PRU), P1_36
(PWM), P2_1 (PWM), P2_3 (default GPIO).

If Adafruit_BBIO.PWM can't change the pin mode, you may have to play
with config-pin external to the program first.

It looks like PWM has also been added to the blinka/circuitpython
adapter.
