近年来随着网络和嵌入式技术的不断发展,嵌入式和网络的结合已经成为最新的研究动态之一。本文中选用嵌入式芯片C8051F020和以太网接口芯片RTL8019AS设计了一种通信接口模块,其中嵌入式芯片C8051F020中嵌入了人为处理后TCP/IP精简协议,与以太网接口芯片RTL8019AS协同工作,共同实现了以太网通信接口的功能。实验表明,本方案具有结构简单、实现方便、实用价值高和成本低等特点。
In recent years, with the continuous development of network and embedded technology, the combination of embedded and network has become one of the latest research developments. In this paper, the choice of embedded chip C8051F020 and Ethernet interface chip RTL8019AS designed a communication interface module, embedded chip C8051F020 embed artificial TCP / IP streamlined protocol, and Ethernet interface chip RTL8019AS work together to achieve Ethernet communication interface functions. Experiments show that this scheme has the characteristics of simple structure, convenient realization, high practical value and low cost.
