LSM303DLHC: Magnetometer and Accelerometer data Monitor

Overview

This sample application periodically reads magnetometer and accelerometer data from the LSM303DLHC eCompass module’s sensors, and displays the sensor data on the console.

Requirements

This sample uses the LSM303DLHC, ST MEMS system-in-package featuring a 3D digital linear acceleration sensor and a 3D digital magnetic sensor, controlled using the I2C interface.

References

Building and Running

This project outputs sensor data to the console. It requires a LSM303DLHC system-in-package, which is present on the stm32f3_disco board
