摘要
以ARM9系列的AT91ARM9200微处理器和LXT971ALE网络接口芯片等构建嵌入式系统,移植Linux,并在RH Linux9.0为ARM处理器提供的交叉开发工具下,完成基于TCP/IP协议的多串口网关的设计。该设备支持服务器和客户机模式,为传统串口设备通过标准TCP/IP协议接入Internet提供了一种低成本解决方案。
Embedded system based on ARM9 MCU AT91 ARM9200 and network interface chip LXT971 ALE is developed, which Linux operation system is ported. Serial port/Ethernet data transfer device through TCP/IP protocol is developed under RH Linux 9.0 and Linux cross development tools for ARM. Server and client mode are supported. It provides a low-coast solution for traditional serial-interfaced equipment to connect with the Intemet.
