The platform bundled SAMD_AnalogCorrection library is only compatible with 12 bit ADC resolution. This can be confusing to the user because: - The definition of ADC_RESOLUTION_BITS in the CorrectADCResponse sketch gives the impression this value can be modified by the user. - The default analogRead() resolution is 10 bits. The first is resolved by the addition of a comment prohibiting changing the value of ADC_RESOLUTION_BITS. The second is resolved by the addition of an `analogReadResolution(12)` call to the code generated by the CorrectADCResponse sketch.
