使用VCNL4200和STM32F410RB在不接触的情况下检测附近物体的存在

 * \brief Proximity 3 Click example
 * 
 * # Description
 * This application reads the raw ALS and proximity data from
 * Proximity 3 click board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the driver and performs the click default configuration.
 * 
 * ## Application Task  
 * Reads the raw ALS and proximity data and displays the results on the USB UART
 * every 500ms.
