6Overview
7********
8This sample sets the date rate of LSM6DSO accelerometer and gyroscope to
912.5Hz and enables a trigger on data ready. It displays on the console
10the values for accelerometer and gyroscope.

15This sample uses the LSM6DSO sensor controlled using the I2C interface
16exposed by the I3C controller. It has been tested using the LSM6DSO on
17the evaluation board STEVAL-MKI196V1 connected to the I3C header
18on :ref:`mimxrt685_evk`.

25Building and Running
26********************
27
28This project outputs sensor data to the console. It requires an LSM6DSO
29sensor (for example, the one on evaluation board STEVAL-MKI196V1).

45------------------
46
47On the board :ref:`mimxrt685_evk`, the I3C pins are exposed on the J18
48header, where:
49
50 * SCL is on pin 1
51 * SDA is on pin 2
52 * Internal pull-up is on pin 3 (which is connected to pin 2 already)
53 * Ground is on pin4

55LSM6DSO
56^^^^^^^
57
58A LSM6DSO sensor needs to be connected to this header. For example,
59the evaluation board STEVAL-MKI196V1 can be used. This needs to be
60prepared so that the LSM6DSO sensor has address 0x6B (i.e. 0xD6,
61left-shifed).
