使用 STS40-AD1B 和 ATmega324P 提供可靠的温度测量

 * @file main.c
 * @brief Thermo24 Click example
 *
 * # Description
 * This example demonstrates the use of Thermo 24 click board by reading and displaying
 * the temperature measurements.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger, then performs the software reset of the click board 
 * and reads and displays its serial number.
 *
 * ## Application Task
 * Reads the temperature measurement in Celsius and displays the results on the USB UART
 * approximately once per second.
