近年來,隨著嵌入式系統的快速發展,越來越多的嵌入式設備被用于工業控制、智能家居等領域。同時伴隨著網絡技術的發展,嵌入式設備通過網絡接入局域網或者Internet已經逐步成為發展的趨勢。通過在嵌入式設備中內置Web服務器,用戶可以在任何一臺聯網的計算機上通過瀏覽器來獲取設備的信息,用戶還可以通過網絡對設備進行配置和管理。因此研究和開發嵌入式Web服務器具有重要的實際意義和應用價值。 本文在S3C44BOX開發板上使用μClinux操作系統作為開發平臺,開發并實現了嵌入式Web服務器。文中提出了2種實現方案,一種是基于boa的嵌入式Web服務器,所做的主要工作是boa在gClinux中的移植和CGI的編寫,在此基礎上實現了動、靜態頁面的生成和簡單的控制功能。另一種方案是基于HTTP協議和socket編程所開發的嵌入式Web服務器,在此方案中實現了HTTP協議的GET和POST請求方式,能夠生成簡單的動態頁面,實現了歷史數據的保存功能,還能夠根據用戶在瀏覽器端的請求進行相應的控制和管理。 論文首先對嵌入式Web服務器的體系結構進行了分析,然后介紹了S3C44BOX硬件開發平臺,并分析了bootloader的基本原理和實現過程。隨后對μClinux操作系統的特點和網卡驅動程序進行了分析,并著重介紹了μClinux的移植過程。在第五章,論文詳細分析了TCP/IP和HTTP的原理和工作機制,并介紹了Web服務器中CGI的工作原理,最后分析了boa服務器的移植和CGI程序的編寫以及Web服務器的測試等。在第六章,在HTTP協議分析和網絡編程的基礎上,提出了嵌入式Web服務器的設計思想、程序流程圖,重點分析了Web服務器主程序流程、動態頁面的生成、歷史數據查詢的實現等,也分析了Web服務器中各種控制功能的實現流程,最后給出了Web服務器的測試結果。

The MSP-FET430PIF is a Parallel Port interface (does not include target board) that is used to program and debug MSP430 FET tools and test boards through the JTAG interface. This interface is included in our FET tools, but sold without the development board. This interface uses a Parallel PC Port to communicate to the Debugger Software (IAR Kickstart software included) running on the PC. The interface uses the standard 14 pin header to communicate to the MSP430 device using the standard JTAG protocol. The flash memory can be erased and programmed in seconds with only a few keystrokes, and since the MSP430 flash is extremely low power, no external power supply is required. The tool has an integrated software environment and connects directly to the PC which greatly simplifies the set-up and use of the tool. The flash development tool supports development with all MSP430 flash parts. Features MSP430 debugging interface to connect a MSP430-Flash-device to a Parallel port on a PC Supports JTAG debug protocol (NO support for Spy-Bi-Wire (2-wire JTAG) debug protocol, Spy-Bi-Wire (2-wire JTAG) is supported by MSP-FET430UIF) Parallel Port cable and a 14-conductor target cable Full documentation on CD ROM Integrated IAR Kickstart user interface which includes: Assembler Linker Limulator Source-level debugger Limited C-compiler Technical specifications: Backwardly compatable with existing FET tool boards.

Firepass - 一種隧道技術工具,通過它可以避開防火墻的規則約束,將數據流封裝在合法的HTTP POST請求中。任何基于TCP/UDP協議的子協議可以通過它來穿越HTTP代理服務器對HTTP協議的嚴格審查。到目前為止,客戶端和服務器端僅用PERL語言編寫。服務器端作為一個CGI腳本運行在WEB服務器上。Firepass的主要特點是用戶可以在外網使用幾種方法安裝服務器端腳本。用戶無需在外網計算機上幫定任何端口。當服務端腳本被置于企業WEB服務器上,客戶端腳本從外部網絡和它通信時,Firepass也可適用于反彈作業。
