Hi everybody, 

I bought a ESP32 PLC 21 and I need to connect it to a stepper motor.

I have a Microstep Driver TB6600 and Nema 17 motor. With classical esp32 tiny board works fine. I know the outputs of the PLC are not actually controlled by the PLC direct pins but by an expader one.

So I check the blog and there were an example for Arduino and not for ESP32, but I thought it would work, unfortunately it does not.

Please does anyone have a snippet code to point me in the right direction?

thank you very much!
