使用MLX75305和STM32F410RB通过调整照明以适应自然光提高能效

 * \file 
 * \brief Ambient Click example
 * 
 * # Description
 * This application turns light intensity into voltage.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver enables GPIO,initializationADC, also write log.
 * 
 * ## Application Task  
 *  This is an example which demonstrates the use of Ambient click board.
 *  Ambient click reads ADC value and converts to light intensity [ uW/cm2 ].
 *  Results are being sent to the Usart Terminal where you can track their changes.
 *  All data logs on USB uart change for every 1 sec.
