UPDATE :

I sent an email to Cytron to see if they had any answers, but, it seems that they are focused on the Raspberry Pi for this board...

HOWEVER, they did give me some information that I think might be helpful

The DIR pins (26 & 24) are looking for 5V for HIGH and 0V for LOW, but when I put a meter on those pins, they are only outputting 3.3V. So, if it needs the full 5V in order to trigger the motors, then it won't work because it's not getting sufficient voltage, so, I guess I'll be going with the RPi, which is not at all what I wanted

Like a fool, even tho I was assured this wouldn't work, I kept on looking for an answer

First I found this...

https://www.seeedstudio.com/blog/2020/05/27/configure-pwm-output-on-jetson-nano-m/

This solution requires rebuilding the kernel, which I am in no way prepared to do, although, I was about to give it a shot anyway, thinking, what could I lose ? All I'd have to do is reflash the sd card. Still, I didn't like that option

Then, Paul McWhorter had something that looked much simpler, so I'm looking into that...

https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/hw_setup_jetson_io.html

Here's his walk-thru...

(I'm following this as I type)

Okay... the test is working when I type the commands directly into python. Now all I need to do is make the right conversions in the code to match the commands that I typed in python.

Other than that, this works, and it's a solution to Jetson Nano PWM

 

YAY !
