使用VL53L1和STM32F103RB改变您感知和互动周围环境的方式

 * @file main.c
 * @brief Proximity15 Click example
 *
 * # Description
 * This example demonstrates the use of Proximity 15 Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration which 
 * enables the sensor and sets it to long distance mode with 50ms timing budget and 100ms
 * inter measurement periods.
 *
 * ## Application Task
 * Reads the distance measured by the sensor in milimeters and displays the 
 * value on the USB UART approximately every 100ms.
 * 
 * @note 
 * In order to measure longer distance, increase the timing budget and inter measurement periods.
