A MotorController is used to drive a motor in forward and reverse directions. It requires 2 Setters as output: one to specify the direction, and one to specify the speed.

Inputs 0 to 127 set direction to 0 (reverse) and speed to 254 to 0 respectively Inputs 128 to 255 set direction to 1 (forward) and speed to 0 to 256 respectively This means than an input of 0 will produce full speed reverse, and input of 127 will produce stop and 255 will produce full speed forward. Truth table: input A B 0 0 254 100 0 54 127 255 0 128 255 2 203 255 146 255 255 256

This is compatible with many motor controllers, such as the Arduino Motor Shield (L298N) (SKU:DRI0009) and many others

Typically the outputs would be a DigitalSetter and an AnalogSetter to control a motor through a digital (direction) and an analog (PWM speed) outputs

Member Function Documentation

failsafe()

void MotorControllerSetter::failsafe ( )

virtual

Called when the source of input data is lost, and the Setter is required to fail in a safe way. Calls the failsafes of targetA and targetB

Reimplemented from Setter.

References Setter::failsafe().

input()

void MotorControllerSetter::input ( int  value )

virtual

Input the value to be used to set the 2 output Setters. Input of 127 produces 255 on A and 0 on B (forward but stopped) Input of 128 to 255 translates to output Setter A to 256 (forward) and output Setter B at 0 to 254 (full speed). Input of 127 to 0 translates to output Setter A to 0 (reverse) and output Setter B at 0 to 254 (full speed).

Parameters

[in]

value

The input value to set.

Reimplemented from Setter.

References Setter::input().

setTargets()

void MotorControllerSetter::setTargets	(	Setter *	targetA,
		Setter *	targetB
	)

Set or change the output pin

Parameters

[in]	targetA	The Setter to use for output A.
[in]	targetB	The Setter to use for output B.

References Setter::setTarget().
