Class AnalogAccelerometer

  • All Implemented Interfaces:
    PIDSource, Sendable, AutoCloseable

    public class AnalogAccelerometer
    extends SendableBase
    implements PIDSource
    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 Detail

      • AnalogAccelerometer

        public AnalogAccelerometer​(int channel)
        Create a new instance of an accelerometer.

        The constructor allocates desired analog channel.

        Parameters:
        channel - The channel number for the analog input the accelerometer is connected to
      • AnalogAccelerometer

        public AnalogAccelerometer​(AnalogInput channel)
        Create a new instance of Accelerometer from an existing AnalogChannel. Make a new instance of accelerometer given an AnalogChannel. This is particularly useful if the port is going to be read as an analog channel as well as through the Accelerometer class.
        Parameters:
        channel - The existing AnalogInput object for the analog input the accelerometer is connected to

      • close

        public void close()
        Delete the analog components used for the accelerometer.
        Specified by:
        close in interface AutoCloseable
        Overrides:
        close in class SendableBase
      • getAcceleration

        public double getAcceleration()
        Return the acceleration in Gs.

        The acceleration is returned units of Gs.

        Returns:
        The current acceleration of the sensor in Gs.
      • setSensitivity

        public void 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:
        sensitivity - The sensitivity of accelerometer in Volts per G.
      • setZero

        public void 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:
        zero - The zero G voltage.
      • setPIDSourceType

        public void setPIDSourceType​(PIDSourceType pidSource)
        Description copied from interface: PIDSource
        Set which parameter of the device you are using as a process control variable.
        Specified by:
        setPIDSourceType in interface PIDSource
        Parameters:
        pidSource - An enum to select the parameter.
      • getPIDSourceType

        public PIDSourceType getPIDSourceType()
        Description copied from interface: PIDSource
        Get which parameter of the device you are using as a process control variable.
        Specified by:
        getPIDSourceType in interface PIDSource
        Returns:
        the currently selected PID source parameter
      • pidGet

        public double pidGet()
        Get the Acceleration for the PID Source parent.
        Specified by:
        pidGet in interface PIDSource
        Returns:
        The current acceleration in Gs.
