I’m looking to drive two servo motors with a PWM Frequency of 9.2kHz using the Jetson Xavier NX.
I understand that Pin 32 and 33 can be configured to PWM using the file: /opt/nvidia/jetson-io/jetson-io.py
After configuration, save and reboot, the configuration doesn’t seem to apply.
To test, I’m using the jetson-gpio library (e.g. simple_pwm.py) to output a PWM signal on pin 33.
Unfortunately the oscilloscope does not show any PWM output on pin 33. Also using the file:
pin 33 is displayed as unused (not PWM output).
In order to configure PWM output on pin 33 and 32, would I need to go through the steps of creating a pinmux configuration file?
If so, can you please outline the steps to take?
