I need to move a big bipolar stepper motor (3.5 Amp) using this driver:
But I don't understand if I have to use just one pin to send the speed to the driver or if I have to use more pins.
Some years ago I used a Unipollar stepper from parallax and the code was like to turn on and off four leds using a chip called ULN.
But this time there are other inputs like DIR- DIR+ , PUL- PUL+ , EN- EN+
I Think that a code like this could move the bipolar stepper:
But I don't understand if I need to use six pins to move the stepper using
DIR- DIR+ , PUL- PUL+ , EN- EN+ ( one for each input)
Do you know where I can see an example to use this driver with a Homework board?
It is very extrange or rare for me.
