I am trying to drive a stepper motor with the Jetson Tk1 and I am running into problems.
I am using a polulu driver, https://www.pololu.com/product/1182 with A4988 chip.
I have followed the GPIO examples and I can turn off/on a LED with Jetson Tk1 OK both form the command line, python and c++
The wiring, driver and motor work OK with my Raspberry PI and even with everything (direction, reset pins, VCC) connected to the Jetson and driving the stepper pin (though the transistor switch) with the RaspPi.
But if I connect the stepper pin (through the transistor switch) to Jetson GPIO the motor moves with very strange behaviour.
I am missing something about the difference between jetson GPIO and RaspPi GPIO.
