Project description

Summary This project implements a KNX (building automation protocol) stack on embedded platforms such as RP2040 and SAMD MCUs, enabling KNX-IP communication over Ethernet. The WIZnet W5500 is used as a wired network interface, providing stable IP connectivity for KNX telegram transport via UDP, particularly suited for deterministic building control systems. What the Project Does KNX is a standardized communication protocol used in building automation systems. It connects devices such as lighting controllers, HVAC systems, sensors, and actuators into a unified control network. Traditionally…
