Arduino Library — Virtuabotixrtch

The VirtuabotixRTC library is an Arduino library (written in C++) that abstracts away the low-level I2C register manipulation required to talk to DS1307 and DS3231 real-time clocks. Unlike the more common RTClib by Adafruit (which requires additional dependencies like Wire.h and TimeLib.h ), the Virtuabotix library is self-contained and minimalistic.
