ST sensors with MLC are also provided with the sensor hub functionality (connection Mode 2). The sensor hub is based on a built-in I2C bus, which can be used from the sensor to acquire other sensors connected to it. With LSM6DSOX the user can acquire up to 4 sensors through its sensor hub.
Data coming from an external sensor can also be used as input for machine learning processing. In this case, the first six sensor hub bytes (two bytes per axis) are considered as input for the MLC. In other words, the MLC will directly take as input the content of the LSM6DSOX registers from SENSOR_HUB_1 (02h) to SENSOR_HUB_6 (07h).
External sensor data can be used in combination with the embedded inertial module to develop your AI-enabled application. Data rate is limited to 104 Hz, more details about the sensor hub mode (Mode 2) are available in THIS application note, chapter 7.
