基于SPI接口的无线网卡设备驱动设计

Design of WLAN adapter device driver based on SPI

介绍了Marvell 88W8686无线网卡芯片在嵌入式linux下的驱动设计与实现.该系统主要应用于心电监护仪和小型手持数据采集系统.首先搭建嵌入式开发的软硬件环境,对linux内核进行裁剪,然后研究网络驱动工作原理,接着对Marvell 88W8686无线网卡的驱动进行修改和交叉编译,最终移植到ARM平台上,建立嵌入式无线局域网.

This paper introduces the design and realization of the Marvell 88W8686 WLAN adapter Linux device driver.It can be used on Electrocardio monitoring instrument and Hand-held data acquisition system.To start with the work,the software and hardware embedded development framework is established.Next,the Linux kernel rebuild and net device driver research are accomplished.In addition,the Marvell 88W8686 adapter device driver is modified and cross-compiled.Finally the Marvell 88W8686 WLAN adapter device driver is immigrated from X86 structure to ARM.Furthermore,the embedded WLAN based on ARM platform is established.
