Problem with TTL-RS232 + CMUCam
For whatever reason, I cannot get the PIC18 to communicate with the camera via the TTL port (shifted to RS-232 of course). I'm 99.9% certain the wiring is correct, and we have 2 level shifters (hopefully both aren't fried) to test with. I'm currently using Kevin's serial port functions and I cannot send or receive anything to/from the camera.

I've even tried loading Kevin's bells and whistles camera program, and that refuses to do anything either (in minicom it just says it is waiting for data). There is no issue communicating with the camera via the DB9 port to the computer (using either minicom or the GUI), so I'm really confused as to what's wrong.

Do I need to set a jumper to enable the 3-pin RS-232 port on the camera, are both level shifters gone, or am I just an idiot (what I'm hoping, we don't really need hardware failure right now)?

Thanks in advance.
