API for 28BYJ-48 Stepper Motor and ULN2003 Driver on Rasperry Pi

A handy API for the 28BYJ-48 stepper motor connected to the ULN2003 driver board and a Raspberry Pi.

Building and installing

$ make

will create libStepperMotor28BYJ48.so in the local directory.

$ sudo make install

will install it to /usr/local/lib

Usage

Before using the API wiringPi must be set up as follows:

#include <wiringPi.h>
...
if (wiringPiSetup() == -1) {
	cerr << "'Failed to setup wiringPi" << endl;
	exit (EXIT_FAILURE);
}

Then operating the motor is straight forward. E.g. if it is connected to the Raspberry Pi using (wiringPi) pins number 1, 4, 5 and 6 and a step duration of 3 milliseconds the just call the following to let the motor perform a little demo.

StepperMotor motor(1, 4, 5, 6, 3);
motor.performDemo();

The documentation in StepperMotor28BYJ48.hpp should be self explaining.
