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`,
:ref:`hexiwear_k64`, and :ref:`twr_ke18f` 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 TWR-KE18F
==================================
TWR-KE18F is equipped with FXOS8700CQ accelerometer and magnetometer.
The FXOS8700CQ IRQ lines, however, are not connected by default, so
motion detection is not supported.
Sample can be built and executed for the TWR-KE18F as follows:
.. zephyr-app-commands::
:zephyr-app: samples/sensor/fxos8700
:board: twr_ke18f
: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
:compact:
