LSM6DSO: IMU Sensor Monitor (I2C on I3C bus)
|
||
|
|
############################################

|
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 :ref:`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_cm33 board

Board Preparations
|
||
|
|
==================

|
|
mimxrt685_evk_cm33
|
||
|
|
------------------
|
||
|
|
|
||
|
|
On the board :ref:`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).
|
||
|
|
|
