On the 650D (And I assume others) you can output an IR signal to an external flash to trigger it, and I believe the camera (As well as others) can receive signals too but I'm not as interested in that right now. What I would like to know is if the transmission is hardcoded or can it be accessed through a module or scripting? Is there an API that can let me control it or if not how would I go about writing C code to do so? Thanks.
