FXOS8700 Accelerometer/Magnetometer Sensor
##########################################

Overview
********

This sample application shows how to use the FXOS8700 driver.
The driver supports FXOS8700 accelerometer/magnetometer and
MMA8451Q, MMA8652FC, MMA8653FC accelerometers.

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

This project outputs sensor data to the console. FXOS8700
sensor is present on the :ref:`frdm_k64f`, :ref:`frdm_kw41z`, and
:ref:`hexiwear_k64` boards. Accelerometer only devices are
present on the :ref:`frdm_kl25z`, :ref:`bbc_microbit`, and
:ref:`reel_board` boards. It does not work on QEMU.

Building and Running for FRDM-K64F
==================================
FRDM-K64F is equipped with FXOS8700CQ accelerometer and magnetometer.
Sample can be built and executed for the FRDM-K64F as follows:

.. zephyr-app-commands::
   :zephyr-app: samples/sensor/fxos8700
   :board: frdm_k64f
   :goals: build flash
   :compact:

Example building for the FRDM-K64F with motion detection support:

.. zephyr-app-commands::
   :zephyr-app: samples/sensor/fxos8700
   :board: frdm_k64f
   :conf: "prj.conf overlay-motion.conf"
   :goals: build flash
   :compact:

Building and Running for FRDM-KL25Z
===================================
FRDM-KL25Z is equipped with MMA8451Q accelerometer.
Sample can be built and executed for the FRDM-KL25Z as follows:

.. zephyr-app-commands::
   :zephyr-app: samples/sensor/fxos8700
   :board: frdm_kl25z
   :conf: "prj_accel.conf"
   :goals: build flash
   :compact:

Building and Running for Micro Bit
==================================
Micro Bit is equipped with MMA8653FC accelerometer.
Sample can be built and executed for the Micro Bit as follows:

.. zephyr-app-commands::
   :zephyr-app: samples/sensor/fxos8700
   :board: bbc_microbit
   :conf: "prj_accel.conf"
   :goals: build flash
   :compact:

Building and Running for reel board
===================================
The reel board is equipped with MMA8652FC accelerometer.
Sample can be built and executed for the reel board as follows:

.. zephyr-app-commands::
   :zephyr-app: samples/sensor/fxos8700
   :board: reel_board
   :conf: "prj_accel.conf"
   :goals: build flash
