IoT entry-level example based on MQTT message communication: GD32E231+ESP8266 implements Wi-Fi remote temperature and humidity collection, control and network clock

This solution is based on the GD32E231 Cortex-M23 core MCU as the main control. The Wi-Fi module uses Essence's ESP8266 and is developed for secondary use. The LCD screen using the SPI interface displays relevant information. The peripheral circuit part uses simple LED lights. Buttons and sensors to complete the demonstration function with the MQTT server.
