摘　　要：文章介绍了基于μC/OS-II操作系统的ARM在以太网方面的应用。在ARM上建立基于TCP协议的远程Web服务器和基于UDP协议的远程智能控制,硬件以ARM7微处理器LPC2214和早期计算机网卡芯片RTL8019AS为核心;软件基于μC/OS-II操作系统,并且移植了TCP/IP协议栈。详细介绍了该系统的系统功能设计、系统结构、硬件电路设计、软件设计及调试的过程和结果。对LPC2214 ARM、RTL8019AS、SST39VF160、IS61LV25616AL、74LV245的主要特性和引脚功能以及内部结构作了简单的说明。对该系统各个组成部分的功能和工作原理作了相应的介绍。This paper mainly introduced ARM＇s application in Ethernet of the operation system of μC/OS-Ⅱ, mainly carrying out on the ARM to build up to negotiate according to the TCP of long range WEB server according to UDP agreement of long range intelligence con- trol, hardware with the ARM7 microprocessor LPC2214 and in early days the calculator net card chip RTLS019AS for the core constituted. Software is based on the operation system of μC/OS-Ⅱ, and transplanted the TCP/IP. The paper will introduce the process and the result design of system structure of the system function, hardware electric circuit design, and design and adjustment of software. It also provides a simple elucidation to the main characteristic of LPC2214, RTLS019AS, SST39VF160, IS61LV25616AL, 74LV245 with led feet function and internal structure. One also introduces constituted part of functions and work principle of this system.
