使用 TMP144 和 ATmega324P 监测和信号传递温度变化

 * @brief Thermo 23 Click Example.
 *
 * # Description
 * This example demonstrates the use of Thermo 23 click board by reading and displaying
 * the temperature measurements.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger, and performs the click default configuration which enables
 * continuous conversion and sets the conversion rate to 1 Hz.
 *
 * ## Application Task
 * Reads the temperature measurement in Celsius and displays the results on the USB UART
 * approximately once per second.
