 * \brief Proximity8 Click example
 * 
 * # Description
 * This application enables usage of the proximity sensor
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization Driver init, test comunication and configuration chip for measurement
 * 
 * ## Application Task  
 * Reads Proximity data and this data logs to the USBUART every 1500ms.
 * 
 * *note:* 
 * The reading value and proximity of the data depend on the configuration.
