使用 TCS3720 和 MK64FN1M0VDC12 实现精准的接近检测、环境光与颜色感测

/*!
 * @file main.c
 * @brief Proximity 22 Click example
 *
 * # Description
 * This example demonstrates the use of the Proximity 22 Click board by reading
 * and displaying proximity, ambient light (ALS), and temperature measurements.
 * The data is read only when a new measurement is ready, indicated by an interrupt.
 *
 * The demo application is composed of two sections:
 *
 * ## Application Init
 * Initializes the logger and the Proximity 22 Click driver, then sets the default configuration.
 *
 * ## Application Task
 * Waits for a data ready interrupt and then reads the proximity, temperature,
 * and ALS data (red, green, blue, and clear channels), displaying the results via UART
 * approximately every 200 ms.
