Compass
|
|
=======
|
|
|
|
The :class:`Compass` provides access to public methods to use compass of your
|
|
device.
|
|
|
|
Simple Examples
|
|
---------------
|
|
|
|
To enable compass::
|
|
|
|
>>> from plyer import compass
|
|
>>> compass.enable()
|
|
|
|
To disable compass::
|
|
|
|
>>> compass.disable()
|
|
|
|
To get the field::
|
|
|
|
>>> compass.field()
|
|
(-23.721826553344727, -5.7114701271057129, -36.749668121337891)
|
|
|
|
To get the uncalibrated field along with iron bias estimation::
|
|
|
|
>>> compass.field_uncalib()
|
|
(a,b,c,x,y,z)
|
|
# a,b,c denote the Geomagnetic field strength
|
|
# (without hard iron calibration) along the three axes.
|
|
# x,y,z denote the Iron bias estimation along the three axes.
|
|
|
|
