StepMotor Class Reference

API for the Stepper Motor. More...

Detailed Description

• ID: stepmotor
• 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 module 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.

    sensor = new upm::StepMotor(4, 6);

    while (!doWork) {
        sensor->setSpeed (500);
        sensor->stepForward (500);
        usleep (10000);
        sensor->stepBackwards (500);
        usleep (10000);

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

        sensor->setSpeed (1000);
        sensor->stepForward (500);
        usleep (10000);
        sensor->stepBackwards (500);
        usleep (10000);
    }

    delete sensor;

Constructor & Destructor Documentation

StepMotor	(	int	dirPin,
		int	stePin
	)

Instantiates a StepMotor object

Parameters

dirPin	Direction GPIO pin
stePin	Stepper pulse PWM pin

Member Function Documentation

void setSpeed

(

int

speed

)

StepMotor object destructor no need for the destructor; all the connections will be closed when m_dirPinCtx and m_pwmStepContext go out of scope ~StepMotor (); Sets the rotation speed

Parameters

speed

Rotation speed

mraa::Result stepForward

(

int

ticks

)

Rotates the motor forward

Parameters

ticks

Number of ticks the motor moves

mraa::Result stepBackwards

(

int

ticks

)

Rotates the motor backward

Parameters

ticks

Number of ticks the motor moves
