基于ARM体系的WIFI移植研究

Study on wifi transplantation for Arm system

在嵌入式系统的应用过程中,为解决高效率的信息传递和网络节点的自由添加删除等问题,本文提出了无线网卡在ARM9体系中实现设备驱动和配置及无线局域网搭建的方案,该方案通过对无线网卡设备驱动和相关设配置工具的移植,实现了无线网卡在嵌入式系统的使用和配置,以C语言为开发语言,实现了无线局域网中不同节点的实时通信,并传递多媒体信息。以低成本,高性能实现了嵌入式设备间的自主组网,以模块化方便了相关产品的二次开发。

In application process of embedded application systems,transmitting the information efficiently and changing the network nodes freely are the problems.To solve the above problems,this paper brought forward a new method to configure and actualize the WLAN Wireless Local Area Networks in the arm9 embedded application systems.By tailoring the device driver and configure tools to the Linux system,WLAN Wireless Local Area Networks in the arm9 embedded application systems is achieved.By using the C programming language,the communication of different nodes in the WLAN Wireless Local Area Networks and the video frame transfers are achieved.This method make the development of wireless lan into modules,so it is convenient for relational production ＇s repeatedly development
