Hmm, well here you're getting a little tricky. Usually a board can't "talk" to another board on a PCI bus, unless you make one of them a bus master. That certainly is possible but I think it's the more complicated solution. > The PIC should read some sensors, and according to an event sequence, > trigger an image frame from the image capture board to the video > out board. This is kinda sounding like a motion activated digital camera, or some such, have you considered commercial options? In the long run (depending on much your time is worth) it might be the cheaper solution. Have you considered perhaps a simpler bus? You could for example go with 16bit ISA cards, FAR more simple to work with.
