Matthew Else / StepperMotor

A simple stepper motor driver library, supporting micro-stepping drivers such as the Pololu A4988 stepper driver carrier or the Sparkfun EasyDriver.

Dependents:   tes_stepper Test_all

Stepper Motor Driver, designed for use with the Pololu A4988 breakout, however more than likely compatible with, for example the Sparkfun Easy Driver
