 * # Description
 * Read the position of magnetic
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes driver init, test communication and configuration device for measurement.
 * 
 * ## Application Task  
 * Reads 3 Axis of the magnetic sensor and logs this data to USBUART every 500ms.
