3. Work Introduction This solution is based on GD32E231 The MCU with Cortex-M23 core is the main control, the Wi-Fi module uses ESP8266 from Anxinke and is secondary developed. The LCD screen with SPI interface displays relevant information. The peripheral circuit uses simple LED lights, buttons and sensors to complete the demonstration function between the MQTT server. This work provides a complete implementation process of IoT project development, from building and configuring the MQTT server to the embedded underlying software and hardware development. Through a simple example, the IoT project process from scratch to the realization of the Internet of Things is truly realized, and the implementation process of IoT is deeply understood. The overall function of the system is relatively simple, mainly to give a cognitive process to those who are new to IoT development. In order to facilitate communication with GD32E231, the Wi-Fi module of ESP8266 has been secondary developed, using custom AT commands for communication, mainly realizing Wi-Fi network connection, synchronization of network time and some related operations with the MQTT server; the LCD screen displays the date and time of the current synchronization network, the current real-time collected sensor data and the current display status of the LED light; the peripheral LED and buttons realize the function of remote communication and control with the MQTT server. 4.

There are also a few blank boards (PCBs). The hardware information can be downloaded upstairs. If you want to learn, leave me a message if you need it. It's free
