【摘要】 本文介绍了D-Link无线网卡在嵌入式Linux下的驱动设计与实现。该系统主要应用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,对Linux内核进行裁剪,然后研究了网络驱动工作原理,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。更多还原

【Abstract】 This paper introduces the design and realization of the USB-WLAN adapter Linux device driver.It can be used on medical gamma camera and SPECT 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 USB-WLAN adapter device driver is modified and cross-compiled according to the general WLAN adapter device driver.Finally the USB-WLAN adapter device driver is immigrated from X86 structure to ARM. Furthermore,the embedded WLAN based on ARM platform was established.It is available to further research on wireless communication.更多还原
