Control motor brushless with esc using jetson nano

Question

I have done a lot of research on how to control a brushless motor with an ESC (Electronic Speed Controller) using a nano jetson. I did not find how to connect the esc to the gpio of the jetson. I also did not find how to make a simple code to control my motor.

If you could help me to clear these points.

Thanks in advance.

Check out the Nvidia Jetson GPIO repository, and the PWM sample. You could for example initiate the PWM-signal to 100Hz like this:

p = GPIO.PWM(output_pin, 100)

And adjust the PWM duty cycle between 0.1-0.2% in order to generate the necessary 1-2ms high pulse PPM signal to set, like this:

p.ChangeDutyCycle(0.1) # 0%
p.ChangeDutyCycle(0.2) # 100%

I am uncertain if the resolution of the Jetson Nano PWM-timers are good enough for this kind of small adjustments, but it is a quick thing to try.
