StepMotor Class Reference

API for the Stepper Motor. More...

Detailed Description

• ID: stepper
• Name: Stepper Motor
• Other Names: EasyDriver Stepper Motor Driver
• Category: motor
• Manufacturer: seeed sparkfun
• Link: http://www.schmalzhaus.com/EasyDriver/index.html
• Connection: pwm gpio

This file defines the Stepper Motor interface. It is compatible with stepper motor drivers that use 2 pins to control the motor, like an Easy Driver from Brian Schmalz.

        usleep (10000);
        sensor->stepBackwards (500);
        usleep (10000);

        sensor->setSpeed (750);
        sensor->stepForward (500);
        usleep (10000);
        sensor->stepBackwards (500);
