使用VL6180X和STM32F446RE创建革命性的测距和距离传感解决方案

/*!
 * \file 
 * \brief LightRanger Click example
 * 
 * # Description
 * This application measures and calculates ambient light intensity and distance 
 * from the sensor, and then logs the results.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver for sensor Vl6180X and stars logging to terminal.
 * 
 * ## Application Task  
 * Measures and calculates ambient light intensity and distance from sensor,
 * when the distance is changed log is updated,
 * results are being sent to the Usart Terminal where you can track their changes.
 * All data logs on usb uart for approximately every 1 sec when the data value changes.
