Detailed Description

Interface to control a standard DC motor with an H-bridge using a PwmOut and 2 DigitalOuts.

Definition at line 34 of file Motor.h.

Constructor & Destructor Documentation

Create a motor control interface.

Parameters:

pwm	A PwmOut pin, driving the H-bridge enable line to control the speed
fwd	A DigitalOut, set high when the motor should go forward
rev	A DigitalOut, set high when the motor should go backwards

Definition at line 25 of file Motor.cpp.

void brake ( int highLow = BRAKE_HIGH )

Brake the H-bridge to GND or VCC.

Defaults to breaking to VCC.

Brake to GND => inA = inB = 0 Brake to VCC => inA = inB = 1

Definition at line 49 of file Motor.cpp.

void period ( float period )

Set the period of the pwm duty cycle.

Wrapper for PwmOut::period()

Parameters:

seconds - Pwm duty cycle in seconds.

Definition at line 43 of file Motor.cpp.

void speed ( float speed )

Set the speed of the motor.

Parameters:

speed The speed of the motor as a normalised value between -1.0 and 1.0
