Detailed Description

Setter class that outputs its value to a HBridge configured on 2 output Setter.

Author:
Mike McCauley (mikem@open.com.au)
A HBridge is used to drive a motor in forward and reverse directions. It requires 2 Setters as output: one to drive the motor forwards and one to drive it in reverse. When driving forward the reverse output is 0 and vice versa.

Typically the outputs would be AnalogSetters to control a motor through a pair of analog outputs, but could be ServoSetter, AccelStepperSpeedSetter or AccelStepperPositionSetter or any other combination.

Member Function Documentation

void HBridgeSetter::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().

void HBridgeSetter::input ( int  value  )  [virtual]

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

Parameters:
[in] value The input value to set.

Reimplemented from Setter.

References Setter::input().

void HBridgeSetter::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().
