Subject: Using UDP in an S-Fcn on xPC target
I was wondering if anybody was able to implement a udp protocol in an S-Fcn on the xPC target? My understanding is that it is very non-trivial, but clearly possible since Mathworks provides both UDP and Real-time UDP blocksets for use with xPC target. I use these blocksets at the moment. I do whatever I need to do in an S-fcn, and then pipe its outputs in Simulink to a Real-time UDP block.
Ideally, I would like to just send stuff over UDP directly out of my S-Fcn. This will allow me to transmit data in a separate thread, or over multiple ethernet adapters.
I cannot obviously use standard win32 libraries to implement udp since they require winsock.dll (or ws_32.dll) to be loaded to the xPC target, which is not supported.
Anybody knows of an approach? Any help is appreciated.
