Arduino Library for the DS3231 Real-Time Clock chip
Updated version of the library originally provided by Eric Ayars
Main changes:
- Updated for Arduino >= 1.5
- Added a method that resets all control & status registers and (re-)enables the alarm interrupt. Some control bits like to randomly toggle when the power is transfered from the backup battery to
Vcc. (I am looking at you,INTCN)
