We can use microcontroller be too work interface chip, replacing the PC site control, the embedded Web Sever system. Field sensor automatically keep track of different monitoring point of information, the detected data stored in nonvolatile memory, and promptly released onto the Inter。 related personnel through a Web technology on the device for remote control, management and maintenance, from the browser on the direct monitoring of field devices running, greatly improved productivity and management level. This article mainly work: 1. to ATmega128 and LAN91C111 as the core of embedded system hardware infrastructure, explains each module specific design process. 2. to μ C/O SI I embedded operating system in the ATmega128 processor of the transplantation process. 3. implementation of the applied to the ATmega128 lw TCP/IP protocol stack. 4. on this basis enables simplified HTTP protocol, and created a based on the ATmega128 embedded Web server systems. Key words: work protocols。 singlechip。 Ether chip。 embedded operating system。 the embedded Web server 無錫科技職業(yè)學院嵌入式系統(tǒng)工程專業(yè) 畢業(yè)設(shè)計（論文） 3 目錄 摘要： ............................................................................................................................. 1 Abstract ............................................................................................................................ 2 硬件選擇 ............................................................................................................ 5 ATmega128的特點 ............................................................................. 5 LAN91C111 ................................................................... 5 NEC公司的 62256 .............................................................................. 6 ..................................................................................................... 6 ........................................................................................... 7 ........................................................................................... 7 ....................................................................................... 8 LAN91C111寄存器地址映射 ............................................................... 8 LAN91C111工作原理 ......................................................................... 8 ......................................................................... 8 LAN91C111驅(qū)動程序設(shè)計 .................................................................. 9 第二章 μC/OS II嵌入式操作系統(tǒng)的移植 ....................................................................... 10 μC/OS II的概述 ............................................................................................ 10 /OS II簡介 .............................................................................. 10 μC/OS II的移植 ............................................................................................ 10 uC/OS II移植的相關(guān)工作 ..............................................................11 ........................................................................... 12 第三章 LwIP在 uCOS II上的實現(xiàn)原理及過程 ................................................................. 14 ................................................................................................................. 14 與 CPU或編譯器相關(guān)的 include文件 ................................................................ 14 sys_arch操作系統(tǒng)相關(guān)部份 ............................................................................. 14 lib_arch中庫函數(shù)的實現(xiàn) ................................................................................ 16 ............................................................................................ 17 第四章 嵌入式 Web服務(wù)器的實現(xiàn) ................................................................................... 18 Web服務(wù)器技術(shù) ..................................................................................... 18 HTTP協(xié)議實現(xiàn) .................................................................................................. 19 .......................................................................................................... 20 4..4嵌入 式 Web服務(wù)器的工作流程 ......................................................................... 22 Web服務(wù)器的實現(xiàn) .................................................................................. 23 謝辭 ............................................................................................................................... 27 參考文獻 ........................................................................................................................ 28
