Hi,
After reinstalling the Ethernet2 Library, it will now compile...
Some how I messed it up...
If I understand what this UDPSendReceive.pde: example does, it works backwords to what i need it to do.
Where the PC Processing C code example, does more like what I want it to do......
I need it to write a retrieve command, then receive the requested data.. Then forward the Data to the PCcoms PC program that normally requests the data, when it requests the data from the Adruino Shield/UNO, and then Process the data to accomplish my project goals....
