Jetson nano to stepper Motor Driver

Could you please provide clarification on whether any digital GPIO (General Purpose Input/Output) pin on the Jetson Nano can be utilized to generate pulses for controlling a stepper motor driver, or is it necessary to connect specifically with PWM pins?

Hi vijay.jangra.1944,

Are you using the devkit or custom board for Jetson Nano?
What’s your Jetpack version in use?

Do you mean that you want to generate PWM signal output from Jetson Nano?

I’m using the devkit. Jetpack 4.6.1

Yes, I need to generate 3 pwm signals from the nano, two of which are available from pin 32 and 33 of the J41 header.
I’m stuck and need help with how I can get the third pwm signal from the nano. @KevinFFF

It seems you could use PIN32 and PIN33 for PWM on 40-pins expansion header.

There’re 3 pins could be used as(pinmux with) PWM. (2 pins you have used, and the 3rd one is used for fan)

Do you mean that you want to use other GPIO as PWM?

i want to use GPIO pins as pwm pin to generate the pulse signal (other than physical pin 32 & 33 in J41 header)
so, is it possible?

Yes, it is possible.
If you want to use GPIO capable pin as PWM, you can refer to soft pwm driver like GPIO PWM driver [] or pwm: Add GPIO PWM driver [].
