Smart central control screen

Overview

The smart home central control screen based on Liangshan School (GD32F450) can automatically obtain/display time, display sensor status information, and can also draw points, lines, rectangles, circles, and display pictures.
Onboard resources:
1. ESP32-WROOM: Connect to the network and connect to the smart home platform (homeassistion) through the MQTT protocol to achieve device status information acquisition and control
2. E18-MS1-ipx: Flash router firmware for extending zigbee signals Coverage, you can choose to connect the zigbee module serial port to GD32 or CH342 chip output
3 through Q1 and Q2 jumpers. CH342: USB to serial port module, supports two serial ports, one is connected to ESP32 serial port 0, and the other can be connected to zigbee through jumpers module.

Demonstration: (The attachment contains a demonstration video)

About jumpers: The burner interface is broken, so solder the wires directly to the motherboard
