To what pin does this go? Just one of the input pins of the
microcontroller? In that case it's a hard guess what it does...
Also, remember that the bits of the GPIO port can be independantly used for
reading and writing, so maybe this pin is used as an input, not an output
like the others.
Sorry for this late reply... I've just sent a patch for supporting
remote vision card. It has some comments included that should explain
these issues...
9: RESET
Reset to what?
reset to crosspoint switch, it breaks all existing conections.
The _vertical_ sync bar? If it looks vertical on your screen, you're
missing the _horizontal_ sync pulses!
All my fault...my cameras are ntsc and i was programming bt848 as
pal...anyway thanks for the help!
It's possible the microcontroller generates the VSync for you, and the
video source that you apply is supposed to sync with this, in stead of
generating it's own sync. In which case you might be screwed :-(
Maybe you can turn it off with the pin to the microcontroller, since the
card _does_ have a sync separator.
There's a sync separator circuit but it doesn't seems to be used, it's
wired to a non existant conector... I guess the microcontroller might
also try to sync channel changes with video sync, dunno.
