How do I implement UDP???

In reference to a previous post of mine http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1276790854/8#8, I have decided to utilize the UDP protocol.

Now the question is how to get started. I'll be using an Arduino Duemilanove with and Ethernet Shield that will be attached to a local computer (this computer controls a submarine). Ultimately the Arduino package will become a remote from which to control the submarine from on a ship's deck rather than below it.

Is there reference material available on or offline that I could use to learn about UDP programming? Can anyone give any hints, suggestions, or tutorial site links that would help?

Thanks!

Try RFC 768 (to start with).

This might also help:

And this:

Finally, this:

BTW - you have googled "arduino udp", right...?

Yeah.. I looked through every link I could find on Google concerning UDP and Arduino. I haven't been able to find anything that gets me started with the basics. I already have the bjoern library. Looking for something now that more or less explains a how to method to get started with the programming.

This might be where you get to be "the first" - at least you have a product that will do it, some sources of information, and some source code.

I'm in the "process" of trying to reverse-engineer the communications protocol of an LCD display for a Lexmark laser printer, and Lexmark isn't giving me -any- love...

;D
