Andrzej Głąbek 20202902f2 dts_fixups: Use DT_ prefix in all defined labels not related to Kconfig These changes were obtained by running a script created by Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following specification: 1. Read the contents of all dts_fixup.h files in Zephyr 2. Check the left-hand side of the #define macros (i.e. the X in #define X Y) 3. Check if that name is also the name of a Kconfig option 3.a If it is, then do nothing 3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it has neither of these two prefixes 4. Replace the use of the changed #define in the code itself (.c, .h, .ld) Additionally, some tweaks had to be added to this script to catch some of the macros used in the code in a parameterized form, e.g.: - CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS - CONFIG_UART_##idx##_TX_PIN - I2C_SBCON_##_num##_BASE_ADDR and to prevent adding DT_ prefix to the following symbols: - FLASH_START - FLASH_SIZE - SRAM_START - SRAM_SIZE - _ROM_ADDR - _ROM_SIZE - _RAM_ADDR - _RAM_SIZE which are surprisingly also defined in some dts_fixup.h files. Finally, some manual corrections had to be done as well: - name##_IRQ -> DT_##name##_IRQ in uart_stm32.c Signed-off-by: Andrzej Głąbek <andrzej.glabek@nordicsemi.no>		2018-11-13 10:44:42 -06:00

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
