RE: [lwip-users] Application example

[Grubb, Jared]

You can’t use the API without an OS. The API is designed around having the TCP/IP stack encapsulated in its own thread in an OS, and the API provides all sorts of hooks and calls to make it all magically work.

We are currently working on some documentation for lwIP, and one of the topics is how to use lwIP without an OS.

An older document on the topic is included in our CVS tree and may be helpful:

Subject: [lwip-users] Application example

 

Hi,
     I am a new user of the LWIP-1.2.0. I have basic understanding of the tcp/ip stack. I was looking for a tcp/ip stack and some one suggested me the lwip stack. I am trying to test a simple client server application using the lwip stack without OS. I have tried to compile the stack but when I use the API I am getting some "sys_sem" errors. I am able to compile the stack without the API. Can some one suggest me where I can find an example to test the stack with and without the API or if possible suggest me how to write an example and test the stack.

Thanks a lot
Rahul
