Detailed Description

Core object for the derived MD_DCMotor_L298 class

This motor controller uses 2 standard digital pins for direction control and one PWM capable pin for speed control.

Constructor & Destructor Documentation

MD_DCMotor_L298()

MD_DCMotor_L298::MD_DCMotor_L298	(	uint8_t	pinIn1,
		uint8_t	pinIn2,
		uint8_t	pinEn
	)

Class Constructor (with PWM control).

Instantiate a new instance of the class. This variant is for motor controllers that have a PWM input for speed control.

The main function for the core object is to initialize the internal shared variables and timers to default values.

Parameters

pinIn1	The In1 pin number for command output to the controller. This is a simple digital pin.
pinIn2	The In2 pin number for command output to the controller. This is a simple digital pin.
pinEn	The En pin number for PWM output to the controller. This is a PWM enabled pin.

Class Destructor.

Release any allocated memory and clean up anything else.

Member Function Documentation

begin()

void MD_DCMotor_L298::begin ( void  )

virtual

Initialize the object.

Initialize the object data. Sets up the pins for output and puts the controlled in a stopped position.

Implements MD_DCMotor.

run()

void MD_DCMotor_L298::run ( runCmd_t  cmd, uint8_t  speed  )

virtual

Run/Stop the motor with speed.

This controls how the motor runs/stops. This sets the motor controller into the correct operating mode and then sets the speed to what is specified. The command specified is one of the runCmd_t values and the speed must be suitable for the setSpeed() method.

See also

setSpeed(), run()

Parameters

cmd	the run/stop mode.
speed	the speed to run at.

Implements MD_DCMotor.

setSpeed()

void MD_DCMotor_L298::setSpeed ( uint16_t  s )

virtual

Set the speed for the motor.

This controls the PWM setting for the motor. Note that the actual speed is dependent on the motor and it is unlikely that it will be a linear response across the range of valid values.

Parameters

s	the speed setting [0..255].

Implements MD_DCMotor.
