Project description
What the Project Does Most W5500 examples focus on basic Ethernet functions such as TCP echo servers, web servers, or MQTT clients. This project goes significantly further by integrating an OPC UA server alongside traditional IoT networking components. The software stack includes: Generated By Chat GPT After booting, the system initializes the W5500, acquires network configuration through DHCP, and starts application services. MQTT examples demonstrate cloud-style messaging, while the OPC UA server exposes structured industrial data to OPC UA clients such as UaExpert. Unlike simple socket…
