I have to realize a communication between Arduino Leonardo and a demon which runs on a pc.
The demon has to tell Arduino informations about the operative system of the machine to which it is linked, as the dimension of the screen and other things about its state, while Arduino is working.
As it has to work both on Windows and on MAC Os, I thought to write the demon in Java, but I've seen that the library RXTX for communication is hardware dependent, so I think it can create problems if I use a different machine (is that true?).
In your opinion how can i solve the problem? Shall I use Processing, or there is another way to achieve that?
Thank you in advance.
