web server sample on FreeRTOS

Posted by Bill Yang on January 26, 2010
Hi,

I am trying to modify the web server in a demo of FreeRTOS. I need to create a web server in my project. So I need to learn how to implement a web server in my program based on a demo of FreeRTOS.

I wonder if someone can contribute and introduce a knowledge regarding the web server design concept. for example, what the httpd.c/h, httpd-fs.c/h, httpd-fsdata.c/h and makefsdata/makefsstrings are doing and how to modify them to expand, add or remove some functions for fit my using. I knew these web pages are based on shtml files in a httpd-fs subdirectory. However I could not get a thread in my mind how to create a web server application as the demo did. I also searched on FReeRTOS web site and could not find some useful materials about the web server demo.

Thanks,
Bill

Have you checked out the uIP documentation?

Davedoors, thank you for your replying.

I've viewed the uIP TCP/IP Stack 1.0 reference manual. Actually it mentioned two functions, httpd-cgi.c, web server script interface and httpd.c the web server. However, I may be rusty on this. I still want to figure out how the web server is going, for example, how the Submit button pressed on IO page to change the LED state, how a device driver is knowing that change has happened and to process a GPIO pin to change a LED state.

I only know the SSI is used in IO.shtml page and CGI has a handler to handle this. But I am not clear how it is going. Or what kind of procedures actually is going.

I wonder if any one can provide a little info or suggest a book I have to read.

Thanks,
BIll
