Hi Rioters, I’ve some troubles about using the ADC on the SAMR21-XPRO board. At now, i’ve added the libraries and required features for it, it compiles and i can use the “periph_adc” test, but i’m not able to find which GPIO are used for the ADC.
In less words, i need an help to start using the ADC lines for a moisture sensor.
I’ve found the watr-li tutorial (http://watr.li/Sensing-moisture.html), but is deprecated.
There is someone who can drive me about it?
Thanks a lot,
