8Overview
9********
10This sample application periodically reads magnetometer and accelerometer data
11from the LSM303DLHC eCompass module's sensors, and displays the sensor data
12on the console.

14Requirements
15************
16
17This sample uses the LSM303DLHC, ST MEMS system-in-package featuring a
183D digital linear acceleration sensor and a 3D digital magnetic sensor,
19controlled using the I2C interface.
