I am trying to use a Nema23 to actuate a peristaltic pump. The program should be triggered by an external I/O signal coming from pin2.
The routine should :
- start by default at slow speed
- when pin is HIGH then reach a desired max speed with a ramp
- when pin 2 is LOW go back to initial speed
Somehow the scale of values i am using doesn't produce any change in speed, and when the pin 2 goes back to LOW is is ignoring the command.
