Abstract:

With the development of communication technology,network communication system has become a main trend. In this paper,W5300 is applied to design and implement the UDP Ethernet communication between PC and embedded terminal. The paper introduces the overall design of the system,describes the working flow of W5300,and presents the typical configuration of W5300 in the system. Experiment results show that unicast and multicast communication by W5300 in the UDP LAN are realized. The system provides a useful reference for the design of embedded Ethernet communication.

Conclusion:

An embedded high-speed Ethernet interface is implemented using the Ethernet communication chip W5300. UDP communication can be realized through simple configuration of the W5300 register. The design scheme is simple, reliable and highly versatile. At the same time, this article also connects multiple communication terminals to computers through switches to form a UDP LAN on this basis, and implements two communication modes: unicast and multicast. The multicast communication function of the W5300 chip is highly scalable and can support computers to communicate with up to 8 groups of device terminals at the same time. It can provide an efficient solution to communication problems in the design of terminal device network clustering.
