:name: X-NUCLEO-IKS01A3 shield - Standard (Mode 1)
:relevant-api: sensor_interface
Interact with all the sensors of an X-NUCLEO-IKS01A3 shield using Standard mode.
Overview
********
This sample is provided as an example to test the X-NUCLEO-IKS01A3 shield
configured in Standard mode (Mode 1).
Please refer to :ref:`x-nucleo-iks01a3` for more info on this configuration.
This sample enables all sensors of a X-NUCLEO-IKS01A3 shield, and then
periodically reads and displays data from the shield sensors:
- HTS221: ambient temperature and relative humidity
- LPS22HH ambient temperature and atmospheric pressure
- LIS2MDL 3-Axis magnetic field intensity
- LIS2DW12 3-Axis acceleration
- LSM6DSO 6-Axis acceleration and angular velocity
- STTS751 temperature sensor
Requirements
************
This sample communicates over I2C with the X-NUCLEO-IKS01A3 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:
- :file:`$ZEPHYR_BASE/boards/arm/nucleo_f401re/nucleo_f401re.dts`
- :file:`$ZEPHYR_BASE/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 sensors multiple instances are not supported.

DIL24 socket
************
In addition to sensors on board it is possible to place any other compatible
sensor on DIL24 socket. The sample is written in such a way that, if sensor is
not present, it will just be skipped.
List of sensors currently supported on DIL24 by this sample:
- LIS2DE12
Building and Running
********************
This sample runs with X-NUCLEO-IKS01A3 stacked on any board with a matching
Arduino connector. For this example, we use a :ref:`nucleo_f401re_board` board.
