VMIX inputs on/off based on a GPIO trigger

Post by philedmonds »

From the iQ manual, regarding VMIX function:
At the top is the V-Mix Master field. This gives the option to assign a Livewire GPIO channel for control of the VMixer. This channel number also gets assigned to a GPIO port, allowing you to have ON/OFF control of
VMix channels through GPIO.
So it appears that if I was to assign a Livewire channel number in the VMIX settings page, and then in the GPIO config page link this Livewire channel to a physical GPIO port on the engine. I would then be able to turn VMIX channels 'on' or 'off' via a GPI input?

In the manual is a table of pin outs for the various GPIO modes, but there isn't details listed for VMIX control. I'd guess that pins 11 through 15 turn on VMIX inputs 1 through 5?

Could you share some details on VMIX GPIO control.

The GPIO port which is linked to the VMIX logic port (have the same number), will control the ON state of the 5 VMIX inputs.

GPI-1 when low will have the input 1 be in the one state. When in the high state, input 1 will be in the off state (latching controls).

When an input is ON, the GPO will be low. So in the above example, when GPI-1 is low, GPO-1 should also be low to indicate the VMIX in-1 is ON.
