Some NIOS FPGA help please?

When you start the web server, the bottom of the page has some hint for you to create your own web server.

In your project directory, there are a few interesting files

- ReadMe.txt

- ro_zipfs.zip

- web_server.c/.h

- http.c/.h

- and all other *.c /*.h

(1) ReadMe.txt

Read the "ReadMe.txt" first, it has some text about this web_server project & little explain on each important c & h file.

(2) ro_zipfs.zip

It is just a zip file, without compression, consist of index.html, and several html pages and pictures. Modify it to suite your web page need, and zip it without compression.

(3) web_server.c

web_server.c is where the main() define

(4) http.c

http.c define the mapping from the web page HTML "POST" request to the actual function call in http.c

Look at

- "post_funcs" that define the mapping struct at http.c line 110,

- "sweep_field" declaration that map HTML POST "/SWEEP" at http.c line 336

- and index.html method=post action="/SWEEP" declaration

-

The function that you need will be very similar to the "choose" & "upload" button and the program_flash.html in the zip file.
