[lwip-users] Application developer guide on wiki

[Pettinato, Jim]

Hmm… since “How do I get a working web server with lwIP?”  seems to be a rather popular question perhaps that would be a good thing to add as a new topic on the wiki. Better yet, I propose we add a new ‘Sample Applications’ section in the Application Developer’s Manual. I was surprised to discover that a search of httpserver on lwip.wikia.com yielded no hits.

Comments? Otherwise I will go ahead and create a new topic and try to get something started on the contrib directory (and the httpserver app specifically) under that section.

Thank you Simon!!

I did not see the contrib package until you commented about it haha. Is ie a pack of examples using the lwIP? Do you have any kind of documentation on how to use the webserver? I could not find the application to turn webpages int the fs to be placed on your system. Do you know where is it and how to use it?

Thank you for your answer!!

Actually, it might be even faster without an OS, depending on what your CPU does besides serving web pages. depending on your main loop, there may be a delay introduced between the MAC receiving a packet and the web server processing it. However, throughput should not be affected.

Don't know about hIp, but there's a web server for lwIP in the contrib module, so you don't have to use the uIP one.

That largely depends on your hardware and the MAC driver.

Take the one from contrib. It has CGI and SSI support by now and is stable enough for my current product... :-)
