homemotor.c

/*

uses the RasPi GPIO ports to bit-band a stepper motor driver.  

uses two ports (defined below) to set the direction and number of stepts.
usage:
~$ sudo ./stepmotor 100 1
steps the motor 100 steps in direction 1.
~$ sudo ./stepmotor 500 0
steps the motor 500 steps in direction 0.

compile
~$  gcc -o stepmotor stepmotor.c -l wiringPi
