Videohub in conjuction with GPI interface ?
In a scenario that includes one BM Videohub used for camera technical setup & color matching and several broadcast remote control camera units, I need to implement joystick override for that video router. This means temporary contact closure on a GPI input => router temporary switches video path to the one programmed for that GPI; when contact releases => router should return video path to its previous status that was set via physical panel or software panel.
I know that the GPI interface can be used with ATEM switchers for driving external tally and I also read/know that the GPI interface has inputs as well (optical isolated, requiring external power etc., but this detail is unimportant for my question).
Question: can I use (configure) in some way the GPI interface so that it acts as joystick override for the Videohub ? (say, 40x40 model) One camera remote control panel = one contact closure when pressing the iris joystick.

However if it's slow paced GPI/relase/GPI/release you'd be fine.
As Duncan says, the interface is sort of Very basic.
You'll be better off using an Arduino with the Skaarhoj Videohub Library (https://github.com/kasperskaarhoj/BMDVideohubClient-Arduino-Library), writing your own custom small commands on the GPIO of the Arduino. This also gives you freedom to choose the amount of GPIO you need.
