使用TCS3530和STM32F103RB实现精确的环境光检测和分析

 * @file main.c
 * @brief Color 18 Click example
 *
 * # Description
 * This example demonstrates the use of Color 18 Click by reading and displaying
 * the values from all 8 modulator channels.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration.
 *
 * ## Application Task
 * Waits for a data ready interrupt then reads data from all 8 modulator channels
 * and displays the results on the USB UART every 200ms approximately.
