使用 TMD2635 和 ATmega328 实现先进的接近测量

 * @brief Proximity17 Click example
 *
 * # Description
 * This example demonstrates the use of Proximity 17 click board by reading and 
 * displaying the proximity data on the USB UART.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger, and performs the click default configuration.
 *
 * ## Application Task
 * Reads the proximity data and displays it on the USB UART approximately once per second.
 * The higher the proximity value, the closer the detected object is.
