The Implement Of Embedded Web Server In The Embedded Experiment Kit

In recent years, with more and more personal computers been interconnected with each other by Internet and embedded devices been used widely, there is a trend that smart information devices are becoming web devices. The Internet web technology satisfies the demand for this trend. This job studies how to implement an Embedded Web Server which is the key of Internet web technology on uClinux.Based on analysis of HTTP engine models used on desktop, a new model appropriate to be implemented on embedded system is raised up. The model can deal with multiple require connections effectively. GET method, POST method and HEAD method are supported according to HTTP specification. CGI is used to make Embedded Web Server be communicated with embedded system, and Basic Authentication Scheme defined in RFC 2617 is supported to make Embedded Web Server more securely on internet.The design of embedded experiment board is introduced firstly in this paper. Secondly, after comparison of common embedded operating systems, uClinux finally is chosen as the embedded OS. The transplant of uClinux and application note of uClinux are also mentioned here. Lastly is the analysis of key technologies of embedded Web Server and the details of Embedded Web Server implementation. How to deal with multiple connections and management of connection FSM is explained in detail.
