Analog comparator polling and manipulation

[dgcaste]

I’m using the VE to drive the iris on a camera. This requires a lot of tweaking of the long potentiometer.

Is there a way to:
– poll the analog comparator to check the current reference voltage? If I find a sweet spot I’ll know what it is so I can just go to more or less that.
– fix the reference voltage through software, like by using a PWM output, instead of tweaking the pot? That’s something I could do in the setup routine for example.
