Hello, I am planning on attempting to build a bipolar stepper driver. I was looking into the wiring diagrams for Bipolar Parallel of an 8 wire motor and I am having trouble understanding how to drive the A, A-, B and B-. I was originally intending on using 4 MOSFETS and a PIC18, but I realize now that the bipolar stepper is going to need more complicated circuitry. I only need to drive in one direction. I am not familiar with an H bridge and my MOSFET are for 30V and 25Amps as I am driving 4 stepper from the 4 MOSFET system. All will move in unison. If you have any suggestions or ideas on how I can make this project come together I appreciate it. Have a nice day.
