Bonjour
J'ai trouvé grace à vous un Tuto qui me permettrait de tester une liaison Ethernet. Ce Tuto possède à la fois un code pour Arduino et un autre pour Processing.
Jestque là, pas de PB. Je mets donc le code pour Arduino dans l'IDE Arduino (Pas de PB ça compile) et je mets le code pour Processing dans l'IDE Pressessing. Et là ça ne fonctionne pas. Il me manque une Lib. Je vais donc la télécharger et essaie de la mettre dans le dossier Libs de Processing.
Mais rien a faire. Que je mette directement le .jar ou le dossier entier le message reste le même.
/*
UDPSendReceive.pde:
This sketch receives UDP message strings, prints them to the serial port
and sends an "acknowledge" string back to the sender
A Processing sketch is included at the end of file that can be used to send
and received messages for testing with a computer.

Voilà le code
La lib manquante est hypermedia
Merci de votre aide
