iOS Data transmission via USB

[wessie]

Hi all,

Firstly i'm an absolute novice as far as iPhone and Cocoa based development is concerned. I've got more extensive knowledge regarding Java and specifically Java-based web applications.

I'm currently starting a project that requires me to be able to transmit data from a third party hardware device into an application deployed to the iPhone via the USB interface. Does anyone know if this is possible and if so, how would I go about doing so?

Any help is appreciated.

Wessie!

Check out the External Accessory framework.

The accessory also has to go through the "Made for iPod" program and get certified.

Is the general way of interfacing to the iPhone USB? I have noticed that much of the External Framework is the same as the USB header except for the Protocol section. I have ported some software over to the iPhone and am in the process of trying to interface the hardware to the iPhone but I haven't gotten into the "Made for iPhone" program yet (working on it).

I know that there is an USB on-the-go set of pins on the dock connector, but is that used for the communication to the PC, or for accessories. I know the dock connector also has RS232 in and out; is that usable?

Any information would be helpful.

TIA!
