摘要
本文采用ARM微控制器LM3S1138和SMSC以太网控制器LAN91C111设计的以太网通信硬件平台,并将μC/OS-Ⅱ实时操作系统和LwIP协议栈移植到该平台上,利用ARM和以太网控制芯片实现的接入方案具有高精度、低成本、高传输率等特点。实现了网络数据传输和仪器的远程控制。
The paper pots forward a scheme of intelligent instrument＇s embedded Ethernet access based on ARM, and expatiates the hardware and software realization. Especially the μC/OS-Ⅱ real-time system and LwIP protocol stack transplanted to processor ARM, and the key software of the LAN91C111 are given. The design realized by single chip processor and network card chip, it has high precision, low cost, high-speed performance and some other characteristics. It provides transparent data communication between intelligent instrument and distant control through Ethernet.
