Detailed Description
Unipolar Type Stepping Motor Driver using 4 Outputs(DigitalOut) with timer interrupt(Ticker)
Driver circuit: Low side driver (4ch for one Stepper) e.g. TD62003AP CAUTION: This is only for Unipolar Type Stepping Motor! Cannot use for Bipolar Type Plese refer http://en.wikipedia.org/wiki/Stepper_motor
