i3c_master_read_sensor_icm42688p#
Overview#
The example shows how to use i3c driver as master to read on board sensor ICM-42688P.
The example will do dynamic address assignment to the ICM-42688P sensor and then reset the sensor for configuration, after that re-do address assign because of address lost. Then enable the ACCEL, GYRO function on sensor. Configure the sensor to generate IBI for TAP detect, then the application continuously read FIFO to retrieve the ACCEL and GYRO data, in the process if you tap the sensor on board, the IBI will generate master handles the IBI, print the IBI data.

Running the demo
The log below shows the output of the example in the terminal window. You could tap the sensor on board(U34) and see sensor read stops, each tap will generate a new IBI data print log “Received slave IBI request.”.
