Minima - Multiple FN Buttons - Cont'd

To properly and simultaneously support different ATMEGA328P packages (e.g., -PU and -MU) for use in the Minima, I suggest the FN push button circuit to be augmented to correctly use the analog AVCC, AREF and AGND pins.

Hopefully this will allow a single Revision of the Sketch to support all ATMEGA328P microprocessor packages.

Note: this circuit and sketch are "alpha" and should only be use to help test this solution.

See the previous post showing the circuit that has been updated.
