Hello program for StepperMotorUni library


Import libraryStepperMotorUni

Unipolar stepper motor operation library


This is just a simple pulse generator for unipolar stepping motor. Use motor driver IC like TD62083 to drive actual motor coils.


The mbed generates pulses on 4 output pins for external driver stage.
The StepperMotorUni library can generate 3 types of pulses.
