Use GPIO as ADC

[Maxim]

Hi, I'am working on a project that use the NRF52832 and i can only use P.23 and P.12 on my custom board because they are already wired to a connector, others pins are not accessible. My goal is to use these pins, who where previously assigned to an external button, as ADC to measure an analogic sensor.

So my question is, is it possible to use these pins as ADC even if they are not referenced as ADC in the pinout avaible HERE ?

Thanks you !

I think it's impossible.

Hi,

The analog inputs are hardwired to the pins described in the Pin assignment documentation, you can't change the physical pin location like you can with the GPIOs.

Best regards,
