Detailed Description

Handle operation of an analog accelerometer.

The accelerometer reads acceleration directly through the sensor. Many sensors have multiple axis and can be treated as multiple devices. Each is calibrated by finding the center value over a period of time.

Constructor & Destructor Documentation

frc::AnalogAccelerometer::AnalogAccelerometer ( int  channel)
explicit

Create a new instance of an accelerometer.

The constructor allocates desired analog input.

Parameters
channelThe channel number for the analog input the accelerometer is connected to
frc::AnalogAccelerometer::AnalogAccelerometer ( AnalogInput channel)
explicit

Create a new instance of Accelerometer from an existing AnalogInput.

Make a new instance of accelerometer given an AnalogInput. This is particularly useful if the port is going to be read as an analog channel as well as through the Accelerometer class.

Parameters
channelThe existing AnalogInput object for the analog input the accelerometer is connected to
frc::AnalogAccelerometer::AnalogAccelerometer ( std::shared_ptr< AnalogInput channel)
explicit

Create a new instance of Accelerometer from an existing AnalogInput.

Make a new instance of accelerometer given an AnalogInput. This is particularly useful if the port is going to be read as an analog channel as well as through the Accelerometer class.

Parameters
channelThe existing AnalogInput object for the analog input the accelerometer is connected to

Member Function Documentation

double frc::AnalogAccelerometer::GetAcceleration ( ) const

Return the acceleration in Gs.

The acceleration is returned units of Gs.

Returns
The current acceleration of the sensor in Gs.
void frc::AnalogAccelerometer::InitSendable ( SendableBuilder builder)
overridevirtual

Initializes this Sendable object.

Parameters
buildersendable builder

Implements frc::Sendable.

double frc::AnalogAccelerometer::PIDGet ( )
overridevirtual

Get the Acceleration for the PID Source parent.

Returns
The current acceleration in Gs.

Implements frc::PIDSource.

void frc::AnalogAccelerometer::SetSensitivity ( double  sensitivity)

Set the accelerometer sensitivity.

This sets the sensitivity of the accelerometer used for calculating the acceleration. The sensitivity varies by accelerometer model. There are constants defined for various models.

Parameters
sensitivityThe sensitivity of accelerometer in Volts per G.
void frc::AnalogAccelerometer::SetZero ( double  zero)

Set the voltage that corresponds to 0 G.

The zero G voltage varies by accelerometer model. There are constants defined for various models.

Parameters
zeroThe zero G voltage.
