| 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). |
