使用OPT3001和STM32G431RB跟踪自然光变化以进行研究和数据分析

 * \brief Ambient2 Click example
 *
 * # Description
 * This is a example which demonstrates the use of Ambient 2 Click board.
 * This example measures and calculates abmient light from OPT3001 sensor.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes I2C driver and all used pins for Ambient 2 click. 
 * Also executes a default configuration for this click, which
 * means that click will work in continuous conversion mode, in automatic full
 * scale range, with conversion time of 800ms.
 *
 * ## Application Task
 * Reads sensor data every time when conversion cycle was done
 * and data was ready for reading. Sends results to the uart terminal.
