SparkFun Qwiic RTC RV-1805 Arduino Library

Qwiic RV-1805 RTC Module (BOB-14558)

The RV-1805 is an extremely precise, extremely low power, highly configurable RTC. Under ideal conditions it runs at approximately 22nA with +/-6ppm per year of deviation (+/- 192 seconds worst case per year).

This library allows the user to:

• Set time using hard numbers or the BUILD_TIME from the Arduino compiler
• Read time
• Configure various aspects of the RTC including setting of alarms, interrupts, and wave outputs

Examples are included to get you started
