Tomasz Bursztyka e18fcbba5a device: Const-ify all device driver instance pointers Now that device_api attribute is unmodified at runtime, as well as all the other attributes, it is possible to switch all device driver instance to be constant. A coccinelle rule is used for this: @r_const_dev_1 disable optional_qualifier @ @@ -struct device * +const struct device * @r_const_dev_2 disable optional_qualifier @ @@ -struct device * const +const struct device * Fixes #27399 Signed-off-by: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com>		2020-09-02 13:48:13 +02:00

X-NUCLEO-IKS01A1: MEMS inertial and environmental multi-sensor shield
#####################################################################

Overview
********
This sample enables all sensors of a X-NUCLEO-IKS01A1 shield, and then
periodically reads and displays data from the shield sensors:

- HTS221: Temperature and humidity
- LPS25HB: Atmospheric pressure
- LIS3MDL: 3-axis Magnetic field intensity
- LSM6DSL: 3-Axis Acceleration

Requirements
************

This sample communicates over I2C with the X-NUCLEO-IKS01A1 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).
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-IKS01A1 stacked on any board with a matching
Arduino connector. For this example, we use a :ref:`nucleo_f429zi_board` board.
