Tomasz Bursztyka e18fcbba5a device: Const-ify all device driver instance pointers Now that device_api attribute is unmodified at runtime, as well as all the other attributes, it is possible to switch all device driver instance to be constant. A coccinelle rule is used for this: @r_const_dev_1 disable optional_qualifier @ @@ -struct device * +const struct device * @r_const_dev_2 disable optional_qualifier @ @@ -struct device * const +const struct device * Fixes #27399 Signed-off-by: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com>		2020-09-02 13:48:13 +02:00

FXAS21002 Gyroscope Sensor
##########################

Overview
********

A sensor application that demonstrates how to use the fxas21002 data ready
interrupt to read gyroscope data synchronously.

Building and Running
********************

This project outputs sensor data to the console. It requires an fxas21002
sensor, which is present on the :ref:`hexiwear_k64` board. It does not work on
QEMU.
