摘要
很多情况下,嵌入式设备需要通过无线网络进行数据传输,这时就可以采用无线网卡作为无线网络接入设备。基于此,分析了Linux系统中网络设备驱动的结构体系及工作原理,研究了基于ARM-Linux平台下无线网络功能的移植实现方案。该方案使用无线网卡作为无线接入设备,通过对无线网卡的移植实现了嵌入式系统的无线网络接入功能。
In many cases, embedded devices need to transmit data through wireless network. Then wireless network card can be used as the wireless network device. Based on the analysis of network device driver structure and working principle in Linux system, a scheme is proposed to implement the wireless network function on ARM-Linux platform. Wireless network card is used as the wireless network device, and is transplanted to the embedded system to implement the wireless network function.
