.. zephyr:code-sample:: lsmd6dso_i2c_on_i3c
:name: LSM6DSO IMU sensor (I2C on I3C bus)
:relevant-api: sensor_interface
Get accelerometer and gyroscope data from an LSM6DSO sensor using I2C on I3C
bus (polling & trigger mode).
Overview
********
This sample sets the date rate of LSM6DSO accelerometer and gyroscope to
12.5Hz and enables a trigger on data ready. It displays on the console
the values for accelerometer and gyroscope.
Requirements
************
This sample uses the LSM6DSO sensor controlled using the I2C interface
exposed by the I3C controller. It has been tested using the LSM6DSO on
the evaluation board STEVAL-MKI196V1 connected to the I3C header
on :zephyr:board:`mimxrt685_evk`.

Building and Running
********************
This project outputs sensor data to the console. It requires an LSM6DSO
sensor (for example, the one on evaluation board STEVAL-MKI196V1).
Building on mimxrt685_evk board
====================================

Board Preparations
==================
mimxrt685_evk
------------------
On the board :zephyr:board:`mimxrt685_evk`, the I3C pins are exposed on the J18
header, where:
* SCL is on pin 1
* SDA is on pin 2
* Internal pull-up is on pin 3 (which is connected to pin 2 already)
* Ground is on pin4
LSM6DSO
^^^^^^^
A LSM6DSO sensor needs to be connected to this header. For example,
the evaluation board STEVAL-MKI196V1 can be used. This needs to be
prepared so that the LSM6DSO sensor has address 0x6B (i.e. 0xD6,
left-shifed).
