Gyroscope
============
The gyroscope measures the rate of rotation around a device's x, y,
and z axis.
The :class:`Gyroscope` provides access to public methods to
use gyroscope of your device.
Simple Examples
---------------
To enable gyroscope::
>>> from plyer import gyroscope
>>> gyroscope.enable()
To disable gyroscope::
>>> gyroscope.disable()
To get the rate of rotation along the three axes::
>>> gyroscope.rotation
(-0.0034587313421070576, -0.0073830625042319298, 0.0046892408281564713)
To get the uncalibrated rate of rotation along the three axes along with the
drift compensation::
>>> gyroscope.rotation_uncalib
()
where the first three values show the rate of rotation w/o drift
compensation and the last three show the estimated drift along the three
axes.
Supported Platforms
-------------------
Android, iOS

Property that returns the rate of rotation around the device's local
X, Y and Z axis.
Along x-axis: angular speed around the X axis
Along y-axis: angular speed around the Y axis
Along z-axis: angular speed around the Z axis
Returns (None, None, None) if no data is currently available.

@property
def rotation_uncalib(self):
'''
Property that returns the current rate of rotation around the X, Y and
Z axis. An estimation of the drift on each axis is reported as well.
Along x-axis: angular speed (w/o drift compensation) around the X axis
Along y-axis: angular speed (w/o drift compensation) around the Y axis
Along z-axis: angular speed (w/o drift compensation) around the Z axis
Along x-axis: estimated drift around X axis
Along y-axis: estimated drift around Y axis
Along z-axis: estimated drift around Z axis
Returns (None, None, None, None, None, None) if no data is currently
available.

WARNING:: This property is deprecated after API Level 8.

Property that returns values of the current Gyroscope sensors, as
a (x, y, z) tuple. Returns (None, None, None) if no data is currently
available.
