I'm quite new to Zephyr, and I have a question related to the nRF52 Adafruit Feather.
As I understand it, this board gives you the ability to measure the voltage on the connected LiPo battery using GPIO 31 (A7).
For a small sensor project, I would like to use this measurement to report on battery level, but I cannot find any guidance on how I might read this pin's value?
Are there any examples you would recommend I take a look at? Any help would be very much appreciated!
