Method Detail

getDegreesCartesian

float getDegreesCartesian()

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.

Returns:

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

resetCartesianZero

void resetCartesianZero()

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