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 (http://developer.apple.com/iphone/library/documentation/ExternalAccessory/Reference/ExternalAccessoryFrameworkReference/index.html).

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!
