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.

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

# On Linux/macOS
cd $ZEPHYR_BASE/samples/sensors/lsm303dlhc
mkdir build && cd build
# On Windows
cd %ZEPHYR_BASE%\samples\sensors\lsm303dlhc
mkdir build & cd build
cmake -GNinja -DBOARD=stm32f3_disco ..
ninja
