rjdj is Pd, but it is like any office iPhone app, so you can dynamically load things, like externals. So rjdj only has its built- in set of objects, which does not include [comport]. You'll definitely have to jailbreak the iPhone to access the serial port, AFAIK.

You can build Pd for iPhone using the pd-mobile-0.43 branch, but the audio I/O code needs to be integrated, so its not included in the branch. Its just a matter of finding the time.

You can use PDa on old iPods and use the serial port, thanks to Tymm Twillman. He even made an Arduino that has a iphone/ipod connector on it, instead of USB, so it literally plugs directly into the iPod/ iPhone. (I cc'ed him, I don't know if he's on the Pd list).

Hi David,
I really like to help by trying on my ipodtouch :itunes does not succeed in, is there another way to install rjdj on ipodtouch 1st generation with last system update ?

Hi Chuck,
Thanks for chipping in.
I need Pd on the iPhone to do the audio component and communication with the Arduino, so I can't ditch rjdj (or whatever way I might get Pd working on the iPhone). I've also poked around and can't find any reference to touchOSC sending anything out of the iPhone's serial pins. My guess is that Patrick is implying that I have Pd running on a separate computer that has the arduino attached to it, which won't work; I need everything done on the iPhone. The solution I'm trying to find is: Pd patch running on the iPhone in communication with an Arduino directly connected to the iPhone.
Still hoping there's a solution to this...
Thanks!
D!

   seems like a more direct route to achieve what you are after.

       Hi Patrick,
       Can you clarify that?
       touchOSC acts as a bridge between rjdj and the serial port?
       RJDJ sends OSC internally to touchOSC which sends stuff out of
       the iPhone serial port? And reverse as well?
       Thanks again,
       D!

                        Hi there list,
           I'm looking at doing a project prototype where the audio
           system is on the iPhone, and it interfaces with an Arduino
           through serial.
I'm assuming since RJDJ is a working version of Pd, I could
           just use it as the engine for this stage of the prototype.
           Does the [comport] object work in RJDJ and can it
           communicate with the external serial port on the iPhone?
And if the answer is "no" or "yes, but," what are my other
           options for using Pd on the iPhone and communicating with
           the serial port?
           Thanks!
           Cheers,
           David
