DTSpec writes this as a single word, presumably to make it easier to grep for / more precise. Follow along in the rest of the docs now that our main DT docs page agrees with this usage. Signed-off-by: Marti Bolivar <marti.bolivar@nordicsemi.no>

X-NUCLEO-IKS01A2: MEMS inertial and environmental multi-sensor shield
|

#####################################################################

|
Overview
|
|
********
|
|
This sample enables all sensors of a X-NUCLEO-IKS01A2 shield, and then
|
|
periodically reads and displays data from the shield sensors:
|
|
|
|
- HTS221: Ambient temperature and relative humidity
|
|
- LPS22HB: Atmospheric pressure and ambient temperature
|
|
- LSM6DSL: 3-Axis Acceleration and 3-Axis Angular Velocity
|
|
- LSM303AGR 3-Axis Acceleration and 3-axis Magnetic field intensity
|
|
|
|
Requirements
|
|
************
|
|
|
|
This sample communicates over I2C with the X-NUCLEO-IKS01A2 shield
|
|
stacked on a board with an Arduino connector. The board's I2C must be
|
|
configured for the I2C Arduino connector (both for pin muxing
|
|
and devicetree). See for example the :ref:`nucleo_f401re_board` board
|
|
source code:
|
|
|
|
- :zephyr_file:`boards/arm/nucleo_f401re/nucleo_f401re.dts`
|
|
- :zephyr_file:`boards/arm/nucleo_f401re/pinmux.c`
|
|
|
|
Please note that this sample can't be used with boards already supporting
|
|
one of the sensors available on the shield (such as disco_l475_iot1) as zephyr
|
|
does not yet support sensors multiple instances.

Building and Running
|
|
********************
|
|
|
|
This sample runs with X-NUCLEO-IKS01A2 stacked on any board with a matching
|
|
Arduino connector. For this example, we use a :ref:`nucleo_f401re_board` board.
