So, I've been doing a bit research about stepper-drivers. I've seen some circuits have the back-EMF diode between the coil and V+ (cathode towards V+), some have it between the coil and ground (cathode towards coil) and some have both.
What's the most "correct" way to do it and why?
Also, would it be smart to use a pull-up or pull-down resistor on the base of my transistor (TIP122) ?
