使用 VEML6046X00 和 PIC32MZ2048EFM100 实现可靠的颜色与环境光测量

 * @file main.c
 * @brief Color 20 Click example
 *
 * # Description
 * This example demonstrates the use of the Color 20 Click board by reading
 * and displaying the ambient light levels in the red, green, blue, and infrared (IR) spectrum.
 *
 * The demo application is composed of two sections:
 *
 * ## Application Init
 * Initializes the logger and the Color 20 Click driver, then applies the default configuration.
 *
 * ## Application Task
 * Reads and displays the red, green, blue (in lux), and IR raw values every 200 ms.
