5 Get accelerometer and gyroscope data from an LSM6DSO sensor using I2C on I3C
6 bus (polling & trigger mode).

8Overview
9********
10This sample sets the date rate of LSM6DSO accelerometer and gyroscope to
1112.5Hz and enables a trigger on data ready. It displays on the console
12the values for accelerometer and gyroscope.

17This sample uses the LSM6DSO sensor controlled using the I2C interface
18exposed by the I3C controller. It has been tested using the LSM6DSO on
19the evaluation board STEVAL-MKI196V1 connected to the I3C header
20on :zephyr:board:`mimxrt685_evk`.

28********************

30This project outputs sensor data to the console. It requires an LSM6DSO
31sensor (for example, the one on evaluation board STEVAL-MKI196V1).

47------------------

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

58^^^^^^^

60A LSM6DSO sensor needs to be connected to this header. For example,
61the evaluation board STEVAL-MKI196V1 can be used. This needs to be
62prepared so that the LSM6DSO sensor has address 0x6B (i.e. 0xD6,
63left-shifed).
