In the graphical datasheet supplied by sparkfun for the SAMD21 Mini Breakout it shows that several pins beyond the A0-A4 broken out on the board are available for use as ADCs.
Is it possible from within the Arduino IDE to configure some of the digital i/o pins to be used as analog inputs? If so, how? I need two additional ADC channels beyond what are currently available. Due to the size of my project I would like to use the Mini rather than the Dev.
Most of Atmel's documentation is focused on using their tools and I have little experience configuring pins on microcontrollers and don't have the budget to pay for Atmel's stuff. I have done some work reading and writing registers on the ATMega328, but that is it.
Any assistance would be greatly appreciated!
