[sysex] is used for MIDI messaging and OSC is designed around network-based communication, hence the ethernet shield.
What I think you want is simple serial communication which is essentially sending / reading raw byte values. I would look into something like http://playground.arduino.cc/Code/CmdMessenger <http://playground.arduino.cc/Code/CmdMessenger>. The basic idea is similar to OSC, a protocol which determines which bytes are what and how to read them back correctly on the other end. I’m sure you could implement the CmdMessanger protocol in Pd using the [list toSymbol], [list fromSymbol], [oscparse], & [oscformat] object, or roll your own. -------- Dan Wilcox @danomatika <https://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/> > On Jun 1, 2016, at 8:29 AM, [email protected] wrote: > > From: Rick Snow <[email protected] <mailto:[email protected]>> > Subject: [PD] Pduino sysex vs. OSC advice > Date: June 1, 2016 at 8:29:16 AM MDT > To: [email protected] <mailto:[email protected]> > > > Hello list! > > I am looking for some advice on sending messages from PD to an Arduino > sketch.
