Method Detail

getDegreesCartesian

public float getDegreesCartesian()

Description copied from interface: DirectionFinder

Compass readings increase clockwise from 0 to 360, but Cartesian coordinate systems increase counter-clockwise. This method returns the Cartesian compass reading. Also, the resetCartesianZero() method can be used to designate any direction as zero, rather than relying on North as being zero.

Specified by:

getDegreesCartesian in interface DirectionFinder

Returns:

Cartesian direction. Between 0 and 360, excluding 360. Values increase counter-clockwise.

startCalibration

public void startCalibration()

Description copied from interface: Calibrate

Starts calibration. Must call stopCalibration() when done.

Specified by:

startCalibration in interface Calibrate

stopCalibration

public void stopCalibration()

Description copied from interface: Calibrate

Ends calibration sequence.

Specified by:

stopCalibration in interface Calibrate

resetCartesianZero

public void resetCartesianZero()

Description copied from interface: DirectionFinder

Changes the current direction the compass is facing into the zero angle.

Specified by:
