通过 VL53L0X 和 STM32F407VGT6 提供的精确距离测量优化流程和工作流

 * \file 
 * \brief LightRanger2 Click example
 * 
 * # Description
 * This example collects data from the sensor, calculates it, and then logs the 
 * results.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver,
 * enable Vl6180X sensor, hardware reset and sets default configuration of
 * Vl6180X, also write log.
 * 
 * ## Application Task  
 * This is a example which demonstrates the use of LightRanger 2 Click board.
 * Measures the distance of the object from the sensor.
 * Results are being sent to the Usart Terminal where you can track their changes.
 * All data logs on usb uart for aproximetly every 1 sec when the data value changes.
 *
