使用Thermostat Click和STM32G474RE根据检测到的温度控制外部设备

/*!
 * @file main.c
 * @brief Thermostat 6 Click Example.
 *
 * # Description
 * This example demonstrates the use of Thermostat 6 Click board by reading
 * the temperature level set using an on-board potentiometer and the temperature
 * from the NTC Thermistor 10k Cylindrical Probe (B57500M0103A005) which is connected
 * to the input, and also displaying the relay state. If the set temperature level
 * is lower than the temperature read from NTC, then the relay switches ON.
 * 
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger.
 *
 * ## Application Task
 * Reads the temperature level set using an on-board potentiometer and the temperature
 * from the NTC Thermistor 10k Cylindrical Probe (B57500M0103A005) connected to the input,
 * and displays the relay state. If the set temperature level is lower than the temperature
 * read from NTC, then the relay switches ON.
