摘　　要：介绍了D-Link无线网卡在嵌入式Linux下的驱动设计与实现。基于医用伽玛相机和小型SPECT设备的手持数据采集系统,首先搭建好嵌入式开发的软硬件环境,分析Linux内核USB驱动模块和网络驱动工作原理,然后针对D-Link无线网卡对通用的无线网卡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,为进一步的无线网络研究搭建好开发平台。It introduces the realization of the USB--WLAN adapter Linux device driver. The system is based on medical gamma camera and SPECT system. Firstly, the software and hardware embedded de- velopment framework is established. According to the analyzing of the USB driver and network driver, the Embedded Linux WLAN adapter device driver was modified and cross--compiled. Finally the USB-- WLAN adapter device driver is immigrated from x86 structure to ARM structure. The embedded WLAN based on ARM structure was established. It is available to further research on wireless communication.
