基于ARM微处理器TCP/IP协议栈LwIP实现

Implementation of LwIP TCP/IP stack with ARM-based MCU

为了给AV3942便携式场强仪提供灵活的网络程控功能,本文提出了一种基于μcosⅡ操作系统的嵌入式TCP/IP协议LwIP的实现方法。在基于ARM微处理器S3C2410和以太网控制器CS8900A的硬件平台上,本文简单介绍了LwIP的移植,并详细阐述了其硬件驱动的具体实现。实验结果表明,该TCP/IP协议能够很好的进行程控命令和数据通信。

In order to provide a flexible network control functions of AV3942 portable field strength instrument, this paper presents the implementation of the embedded TCP/IP protocol with ucos Ⅱ. In the hardware platform with ARM- based microprocessor S3C2410 and Ethernet controller CS8900A, It briefly introduced the transplantation of LwIP, and expatiated primarily the concrete realization of the hardware-driven. The results show that the TCP/IP protocol can be good for program-controlled commands and data communications.
