## ◆ AnalogTrigger() [1/4]

 frc::AnalogTrigger::AnalogTrigger ( int channel )
explicit

Constructor for an analog trigger given a channel number.

Parameters
 channel The channel number on the roboRIO to represent. 0-3 are on-board 4-7 are on the MXP port.

## ◆ AnalogTrigger() [2/4]

 frc::AnalogTrigger::AnalogTrigger ( AnalogInput * input )
explicit

This should be used in the case of sharing an analog channel between the trigger and an analog input object.

Parameters
 input The pointer to the existing AnalogInput object

## ◆ AnalogTrigger() [3/4]

 frc::AnalogTrigger::AnalogTrigger ( DutyCycle * dutyCycle )
explicit

Construct an analog trigger given a duty cycle input.

Parameters
 dutyCycle The pointer to the existing DutyCycle object

## ◆ ~AnalogTrigger()

 frc::AnalogTrigger::~AnalogTrigger ( )
override

## ◆ AnalogTrigger() [4/4]

 frc::AnalogTrigger::AnalogTrigger ( AnalogTrigger && )
default

## ◆ CreateOutput()

 std::shared_ptr< AnalogTriggerOutput > frc::AnalogTrigger::CreateOutput ( AnalogTriggerType type ) const

Creates an AnalogTriggerOutput object.

Gets an output object that can be used for routing. Caller is responsible for deleting the AnalogTriggerOutput object.

Parameters
 type An enum of the type of output object to create.
Returns
A pointer to a new AnalogTriggerOutput object.

## ◆ GetIndex()

 int frc::AnalogTrigger::GetIndex ( ) const

Return the index of the analog trigger.

This is the FPGA index of this analog trigger instance.

Returns
The index of the analog trigger.

## ◆ GetInWindow()

 bool frc::AnalogTrigger::GetInWindow ( )

Return the InWindow output of the analog trigger.

True if the analog input is between the upper and lower limits.

Returns
True if the analog input is between the upper and lower limits.

## ◆ GetTriggerState()

 bool frc::AnalogTrigger::GetTriggerState ( )

Return the TriggerState output of the analog trigger.

True if above upper limit. False if below lower limit. If in Hysteresis, maintain previous state.

Returns
True if above upper limit. False if below lower limit. If in Hysteresis, maintain previous state.

## ◆ InitSendable()

 void frc::AnalogTrigger::InitSendable ( wpi::SendableBuilder & builder )
overridevirtual

Initializes this Sendable object.

Parameters
 builder sendable builder

Implements wpi::Sendable.

## ◆ operator=()

 AnalogTrigger & frc::AnalogTrigger::operator= ( AnalogTrigger && )
default

## ◆ SetAveraged()

 void frc::AnalogTrigger::SetAveraged ( bool useAveragedValue )

Configure the analog trigger to use the averaged vs.

raw values.

If the value is true, then the averaged value is selected for the analog trigger, otherwise the immediate value is used.

Parameters
 useAveragedValue If true, use the Averaged value, otherwise use the instantaneous reading

## ◆ SetFiltered()

 void frc::AnalogTrigger::SetFiltered ( bool useFilteredValue )

Configure the analog trigger to use a filtered value.

The analog trigger will operate with a 3 point average rejection filter. This is designed to help with 360 degree pot applications for the period where the pot crosses through zero.

Parameters
 useFilteredValue If true, use the 3 point rejection filter, otherwise use the unfiltered value

## ◆ SetLimitsDutyCycle()

 void frc::AnalogTrigger::SetLimitsDutyCycle ( double lower, double upper )

Set the upper and lower duty cycle limits of the analog trigger.

The limits are given as floating point values between 0 and 1.

Parameters
 lower The lower limit of the trigger in percentage. upper The upper limit of the trigger in percentage.

## ◆ SetLimitsRaw()

 void frc::AnalogTrigger::SetLimitsRaw ( int lower, int upper )

Set the upper and lower limits of the analog trigger.

The limits are given in ADC codes. If oversampling is used, the units must be scaled appropriately.

Parameters
 lower The lower limit of the trigger in ADC codes (12-bit values). upper The upper limit of the trigger in ADC codes (12-bit values).

## ◆ SetLimitsVoltage()

 void frc::AnalogTrigger::SetLimitsVoltage ( double lower, double upper )

Set the upper and lower limits of the analog trigger.

The limits are given as floating point voltage values.

Parameters
 lower The lower limit of the trigger in Volts. upper The upper limit of the trigger in Volts.
