rudcode / DS3231

Communicates between Arduino-programmed AVR and Maxim DS3231 RTC: splice of Ayars' (http://hacks.ayars.org/2011/04/ds3231-real-time-clock.html) and Jeelabs/Ladyada's (https://github.com/adafruit/RTClib) libraries

DS3231

Library to communicate with Maxim's DS3231 high-precision real-time clock (RTC)

Eric Ayars DS3231 library with JeeLabs/Ladyada's RTC libraries spliced in by Andy Wickert

Released into the public domain by Jeelabs, Ladyada, and Eric Ayars; public domain release maintained by Andy Wickert, as his changes were mostly minor: splicing the libraries, Arduino 1.0 compatibility for Eric's DS3231 library, and adding an example or two.
