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
