 * 
 * # Description
 * This application measures magnetic and accelerometer axes data and shows them over USBUART
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver init and init chip
 * 
 * ## Application Task  
 * Read magnet axis data and accel axis data and logs data on USBUART every 1 sec.
