 * 
 * # Description
 * Measures proximity data and ambient light.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver init and sets chip on the default mode
 * 
 * ## Application Task  
 * Reads Proximity data and Ambient light data and logs data to USBUART every 500 ms.
