嵌入式系统网络通信软件设计

Networks communication software design of Emeded system

本文以业界领先的32位RISC微处理器ARM开发板为硬件平台,结合EMBEFT IDE集成开发环境,在仔细研究和分析板上资源的基础上,从嵌入式系统开发网络通信的角度,在详细分析了嵌入式硬件开发平台资源的前提下,实现了嵌入式系统的网络通信功能。实现了TFTP协议在网络控制器RTL8019上的数据传送和远程监控。此外,根据未来发展需要,提供了相当的扩展空间,包括RTOS实时设计方案,从而实现更高效的嵌入式网络通信系统。

First,combined with the integrated development environment of EMBEFT,microprocessor of 32 bits ARM development board,which is of the leading in the corresponding field,has been treated to be the hardsoft plat in this paper,besides,the sources of boards have been researched and analyzed carefully.Then,from the angle of developing networks communication of embedded system,the flat resources of embedded hadrwork development have been analyzed in detail,and embedded network communication systems can be realized.Moreover,TFTP agreement on data transmission and long-distance surveillance and control has been implemented.In addition,according to the needs of future developments,relative expanded space has been provided including real-time design schemes of RTOS,so that efficient embedded network communication systems can be realized.
