Zoltan Hudak / Clock

Software implemented real time clock driven by a Ticker. No external hardware (like DS1307 or DS3231 or etc.) is needed. Should work on any mbed platform where Ticker works.

Dependents:   Clock_Hello

See demo:

Import programClock_Hello

Demo for the Clock library (real time clock driven by a Ticker).
