摘要
叙述了采用ARM微控制器S3C44B0X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低成本、高传输率等特点。实现了网络数据传输和仪器控制。
This paper puts forward a scheme of intelligent instrument＇s embedded Ethernet access based on ARM ,and expatiated on 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 has low cost,high-speed performance and some other characters. It provides transparent data communication between intelligent instrument and distant terminal through Ethernet.
