摘要
为了实现嵌入式系统中增加无线通信的功能,建立嵌入式无线网络,可以在系统中使用无线网卡。介绍了一个嵌入式微处理器和实时操作系统的无线接入网的设计方案,阐述了基于ARM LPC2119微处理器的外围硬件电路的接口方法,讨论了实时操作系统μCOS-II、TCP/IP的移植和实现,以及无线网卡的整体构架和USB网卡驱动程序设计的关键技术,实现了USB无线网卡在嵌入式系统平台上的应用。
In order to realize the wireless communication functions in embedded system,establish the embedded wireless network, wireless network card can be used in the system.This paper presents the design of embedded microprocessor and a real-time operating system access wireless network,describes the external hardware interface method based on the ARM LPC2119 microprocessor,and discusses real-time operating system μCOS-Ⅱ,TCP/IP transplantation and realization,the framework of wireless network card and the key technologies of USB driver design,to achieve the USB wireless network card applications in embedded system platform.
