If someone knows about this ioctl to set/read gpio pins directly, could you please post it? I have a PC/104+ bt878 card (it's called a Sensoray 311) that has some of the gpio pins just routed to a header for doing generic digital io (which could be used for camera triggering, for example). It would be fun to try it out.
As for the 16-camera multiplexer, it may be easy to figure it out if you can find out which chip the mux is, and how it's connected to the bt848. It seems to me that the way they'd do it would be to switch 4 lines at a time, since the 848 has a 4-way mux internal to it. Clay Gleicon S.
