Working Version of the Real Time Clock module DS1307.
Dependents: Rtc_Ds1307_Sample TAREA_5_PROCESADORES Rtc_Ds1307_lcd_alarma Rtc_Ds1307_Reloj_con_alarma_aplazable ... more
This is my implementation of the DS1307.
I plan to add functionality which will make use of the OSC Input and which will increment the time continuously. A query to the module will then only have to be made when the MBED has been powered down.
