HiI think it's easier to program the steps for the circuit with 2 pins. But i can't tell how the stepping is actually made.Have you thought about using an L297? That would take A LOT of programming off your shoulders. It just needs a clock source (could be a simple PWM signal), and a direction input (high or low).Good luck.
Hi,How flexible is this to program ? Can I control how fast, how long and/or how many steps to turn, which waveform etc. ? Can you please point me to a circuit ? I have Arduino board, any idea how to input clock source to L297 ?Thanks,RO.
I am looking at http://arduino.cc/en/Reference/StepperBipolarCircuit where it shows two circuits to drive a bi-polar stepper motor. One has 2-pins that go to the controller and the other has 4 pins that go to the controller. I am wondering what is the advantage of one versus the other. The 4-pin circuit seems simpler to build but I end up using 2 extra pins whereas the 2-pin one is (comparatively) harder to build but saves 2-pins, which will be useful if I want to drive multiple steppers.
If you wanna use the L297, be prepared for a larger circuit, like adding a L298 or similar as the L297 in itself isn't able to drive your motor.
