Radoslaw Koppel d1a93c1426 drivers: sensor: Const sensor trigger data in trigger handler This commit adds const modifier in second argument for sensor trigger handler. There is no reason to modify this data and this change would allow to store trigger configuration also in FLASH.

LIS2DH: Motion Sensor Monitor
#############################

Overview
********

This sample application periodically reads accelerometer data from the
LIS2DH sensor (or the compatible LS2DH12, LIS3DH, and LSM303DLHC
sensors), and displays the sensor data on the console.

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

This sample uses the LIS2DH, ST MEMS system-in-package featuring a 3D
digital output motion sensor.

Building and Running
********************

The LIS2DH2 or compatible sensors are available on a variety of boards
and shields supported by Zephyr, including:

* :ref:`actinius_icarus`
* :ref:`thingy52_nrf52832`
* :ref:`stm32f3_disco_board`
* :ref:`x-nucleo-iks01a2`

See the board documentation for detailed instructions on how to flash
and get access to the console where acceleration data is displayed.

Building on actinius_icarus
===========================

:ref:`actinius_icarus` includes an ST LIS2DH12 accelerometer which
supports the LIS2DH interface.

Building on nucleo_l476rg with IKS01A2 shield
=============================================

The :ref:`x-nucleo-iks01a2` includes an LSM303AGR accelerometer which
supports the LIS2DH interface.  This shield may also be used on other
boards with Arduino headers.
