The Design And Implement Of Embedded Webserver Platform

The embedded system based on Internet is at a rapid developing stage and more and more embedded devices are attempting to get the access to Internet.with the advancement of MCU processor,the applications are forced to be divided into various independent task modules and ensure the event that is real-time characteristic can be processed at the same time.So we must have the real-time operating system embedded and realize the real embedded application.It becomes the important search direction in embedding field that TCP/IP protocol stack is introduced to the embedded real-time operating system in order to support the access of embedded devices to network.The intention of this paper is that enable embedded real-time operating system (RTOS)μC/OS- II and the most-frequently-used network protocol TCP/IP to be combined and transplanted into the MCU SPCE061A which consists of a built-in 32k-word program Flash storage and the control chip of DM9000 ETHERNET interface.What this paper accompletes is the design and realization of the embedded WEB SERVER platform based on RTOS and TCP/IP protocol stack.the main tasks are as follows:1 realizing the receiving and sending of data package by DM9000 driver.2 realizing the interface of bottom network device driver and uIP protocol stack and of uIP and main control function.3 realizing the transplant of embedded μC/OS-Ⅱ operating system with open source in SPCE061A and the partition of task modules.4 obtaining the communication data of system and Internet via the free-of-charge Ethereal tool with the intention of verifying the feasibilityIn addition, the lower development cost is the prominent feature of this system.
