NRF51822: Pins selectable as ADC inputs?

[Dan B]

Which pins are mapped as ADC inputs for the NRF51822? I've pored over the documentation, but I can't seem to find which ADC pins (AIN0 to AIN7) correspond to which GPIO pins (P0.0 - P0.31).

If it matters, I am currently using the NRF51822 evaluation kit.

Thanks,

Dan

It is listed in the "Pin assignments and functions" section of nRF51822 Product Specification.

Thank you for pointing this section out. I was taking ADC measurements from AIN2 which is BUTTON_1. I never thought they'd be the same pin but my button suddenly stopped working when I implemented ADC measurements. Problem solved.
