I have a problem with my understanding of how to control a motor driver from a Raspberry Pi. Ideally I’d like to use Windows IoT as that is the base of my experience. But I could also use a different framework if necessary. My questions are:
- Using the Dir and Step pins, is all I need to do is pulse the Step pin (High-Low) to get the motor to perform one step? Or do I need to simulate a PWM signal on the pins?
- Is this the best interface to use from a Pi? Or, should I use a serial interface if available?
I have a Tic T825 board and can control my motor from the Windows App just fine. But if I pulse the pins, I don’t get any motor movement.
I also will have some A4988 controllers and have basically the same question.
Any pointers to samples, or libraries for the motor drivers would be greatly appreciated.
