使用 G6D-1A-ASI 和 STM32G071RB 保持研究和实验的理想条件

/*!
 * @file main.c
 * @brief Thermostat 2 Click Example.
 *
 * # Description
 * This example demonstrates the use of Thermostat 2 Click board by reading
 * and displaying the temperature in Celsius and turning the relay on/off 
 * depending on the temperature value.
 * DS1820, DS18S20 and DS18B20 chips can be used in this example. 
 * 
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration.
 *
 * ## Application Task
 * Reads and displays the temperature measured by the Click board on the UART Terminal.
 * If the temperature goes beneath the THERMOSTAT2_TEMPERATURE_LIMIT, 
 * the relay will be turned off while otherwise it will be turned on. 
 * In both cases an appropriate message will be displayed on the terminal.
