使用MLX90641和STM32G474RE实现非接触温度测量和热成像

 * @brief IR Grid 4 Click example
 *
 * # Description
 * This example demonstrates the use of IR Grid 4 Click by reading and displaying
 * the ambient and object temperature measurements in a 16x12 pixels grid format.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration.
 *
 * ## Application Task
 * Reads the ambient and object temperature measurements every 500ms and displays
 * the results on the USB UART in a form of a 16x12 pixels grid.
