potentiometer on the STM32F746G

I was hoping to wire an external potentiometer to the ADC on the STM32F746G but even bypassing the input cap (C107) I still seem to get AC readings.  E.g. I bump the pot one way and I get a positive blip, I bump it the other I get a negative blip.

I read stuff suggesting previous STM32 boards had an onboard pot but unless I'm missing something really obvious in the manual I don't see a pot on the 746G.  Is that correct?

Any ideas how to get a multi-valued DC control signal into the board?

Again, I did a brief search here but the site is so slow it tends to discourage much searching.
