Looking for a better way to drive AON GPIO to simulate GPIO.

Is there some way through changing FreeRTOS source code so that we can drive AON GPIO to high/low to simulate a PWM output? Cause our customer asks for 4 PWM on SPE, and adopting interfaces in /sys/class/gpio seem a easy method, but that too many calls surely make CPU work heavily. So we want realize the PWM in RTOS layer.


hello garretzou,

you might refer to https://pypi.org/project/Jetson.GPIO/,
for the details about how to configure the system and run the provided sample applications, and the library API.
