Problem about LAN

I suggest you read chapter 8 of the Nios II Software Developers Handbook.

The answer to your question is that if you use LWIP and MicroC/OS-II you can just use sockets. You should probably look at the web server example which comes with the kit.

I' ve to use Lwip on nios2, but without MicroC/OS-II, i cannot use socket api?

Do I have to use raw api? Where can i find an example of a tcp server similar to the one

in chapter 8 of the Nios II Software Developers Handbook?

Thank a lot,

Michele

If you can't use MicroC/OS-II and you wish to use LWIP you have to use the raw API. All the documentation there is can be found in the directory altera\kits\nios2\components\altera_lwip\UCOSII\src\downloads\lwip-1.1.0\doc\rawapi.txt. That said you'll need to modify the code to work standalone, http://www.niosforum.com/forum/index.php?a...t=st&f=16&t=949 (http://www.niosforum.com/forum/index.php?act=st&f=16&t=949) may be a good starting point.

Or you could look at eCos which contains an IP stack and has a sockets API.

Thank you for answer me.

I can't use any OS, i' ve just seen rawapi.txt

but I&#39;ve some difficulties with prototypes... http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif

and so I&#39;m searching for some example to study.

I&#39;ve seen the "Lwip_web_server" example,

it&#39; s an http server, but I need only a simple tcp server.

Thank you for help.

There is a standalone port of LWIP with a sample echo server & HTTP server .

If you cannot use an OS, you will need to use rawapi , so the functions need to be implemented as callbacks, i have an example i can forward.

Send me an email to ppk03100 at utdallas dot edu and i will forward it
