X-NUCLEO-IKS4A1: shield SHUB2 (Mode 2) sample

Overview

This sample is provided as an example to test the X-NUCLEO-IKS4A1 shield configured in Sensor Hub mode (Mode 2). Please refer to Mode 2: LSM6DSO16IS SensorHub Mode (SHUB2) for more info on this configuration.

This sample enables LSM6DSO16IS IMU in sensorhub mode with LIS2MDL magnetometer and LPS22DF pressure and temperature sensor.

Then sensor data are displayed periodically

  • LSM6DSO16IS 6-Axis acceleration and angular velocity

  • LSM6DSO16IS (from LIS2MDL) 3-Axis magnetic field intensity

  • LSM6DSO16IS (from LPS22DF) ambient temperature and atmospheric pressure

Requirements

This sample communicates over I2C with the X-NUCLEO-IKS4A1 shield stacked on a board with an Arduino connector, e.g. the ST Nucleo F411RE board.

Building and Running

This sample runs with X-NUCLEO-IKS4A1 stacked on any board with a matching Arduino connector. For this example, we use a ST Nucleo F411RE board.
