Send and receive TCP packages

PEGE — Tue, 20 Dec 2011 23:30:21 GMT

Hello,

I am using a mcf52xx and i am trying to send and receive TCP packages between my evb and my PC. The PC is running a server on port 4444, and my controller includes the fnet TCP/IP stack. Now I am looking for a tutorial or some information about the steps I have to do.

Especially the creating of a new socket is my problem.

Is it possible to use interrupts if the µc receive a TCP package ?

Friendly regards peter

Hi Peter,

>> Is it possible to use interrupts if the µc receive a TCP package ?

Yes. FNET does not use the HW blocking of interrupts.

So it perfectly coexists with Real Time applications.

>>Now I am looking for a tutorial or some information about the steps I have to do.

FNET uses socket approach. There is a lot of information “how to use sockets” on Internet.

I suggest using the FNET-services (client/server) source code and demo-projects, as a tutorial/reference.

Thanks,
