Timing
Real Time functions for Goldilocks ATmega1284p & ATmega2560
This library implements a RTC on an ATmega with a 32kHz clock crystal on Timer 2, supporting the avr-libc time.h functions.
Maintainer: Phillip Stevens
This library is compatible with the avr architecture so you should be able to use it on the following Arduino boards:
Note: while the library is supposed to compile correctly on these architectures, it might require specific hardware features that may be available only on some boards.
To use this library, open the Library Manager in the Arduino IDE and install it from there.
