Ethernet Input

Jawwad

I am trying to take an input from the ethernet port as a string, and then break that string down and assign values from there to an array. I tried going through the LWIP webserver demo, but I didnt really understand all too well what was happening. Can someone simplify how to take an input via ethernet and output. It just needs to be a text file.

Thanks

Hi Dean,
For lwIP specific question I'm afraid we don't have the expertise to answer. You can try the mailing list / forum on the project page savannah.nongnu.org/.../

You might below post helpful posted by Szilard Lovas who is very knowledgeable in this area.

I'm on the wiki page. I want to know the IP address of my TI device, the wiki page says Enable the Ethernet on EVM by setting switch S2 bit4 to On, I dont know what this means? EVM? and which switch? So I'm trying to plug the TI board into the router to see if it gets an IP, but my router cant find the device it doesnt even show up

See the picture below. There is a S2 switch at the corner of the HDK board. You need to set bit4 to turn on ethernet.

I tried this example but for some reason it does not build I get an error
#1965 cannot open source file "lwipopts.h" opt.h /Build-LAUNCHXL2-570LC43/lwip-1.4.1/src/include/lwip line 45 C/C++ Problem

Also I tried plugging my TI to the router via ethernet right out of the box in hopes that I could get an IP address on it but my router doesnt even see it

please advise.
Thanks
