No Way to Reset PWM_hat. #34

Closed delers447 closed 2 years ago

delers447 commented 2 years ago

Hello!
I followed this tutorial off the adafruit webpage:
https://cdn-learn.adafruit.com/downloads/pdf/adafruit-16-channel-pwm-servo-hat-for-raspberry-pi.pdf

I am making a robotic arm and after my code stops the pwm_hat is still broadcasting the PWM signal to the servos. I am looking for a way to stop the signal.
On page 17 of the linked documentation it says to substantiate the pwm object

pwm = PWM(0x40)

and then call the method setPWM(). I wanted to use the method

pwm.setPWM(servo, 0, 0)

to make the signal low on all ticks. The issue is non of the libraries have the class PWM. I even did

from PCA9865 import *

and still nada.

Could this servo kit library give a way to reset the PWM Hat to stop broadcasting?

The library reference of that PDF is incorrect. (This Learn guide page.)

Please stick to one support method while we sort out an issue. (Forum post here: https://forums.adafruit.com/viewtopic.php?f=60&t=186459 )
