基于ARM的嵌入式系统以太网通讯设计

Ethernet Communication Design of Embedded System Based on ARM

介绍了一种基于ARM的嵌入式系统以太网通讯方法。采用LPC2368微控制器与以太网物理层芯片DP83848进行硬件设计,对μC/OS-Ⅱ操作系统的移植建立开发环境,在此基础上进行TCP/IP协议栈的设计,实现socket通信。此方案实现了嵌入式以太网的数据传输并成功应用于电场仪数据采集及通信系统中。

This paper introduces an embedded communication system based on ARM.The use of LPC2368 microcontroller chip and DP83848 physical chip are conducted to design the hardware,the transplant process of μC/OS-Ⅱ is accomplished to establish development environment,based on which designs the TCP/IP protocol and implements socket communication.The solution realizes data transmission of embedded communication system and has been applied successfully in the data collection and communication system of electric instrument.
