使用OPT4060和STM32F103RB测量颜色和光强

 * @file main.c
 * @brief Color 19 Click example
 *
 * # Description
 * This example demonstrates the use of Color 19 Click by reading and displaying
 * the color measurement from RGBW channels and the light intensity level in lux.
 *
 * 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 the color measurement from 
 * RGBW channels and the light intensity level in lux and displays the results
 * on the USB UART every 200ms approximately.
