the class is able to decode the signal of a connected DCF77-Receiver-Module. It also provides a softclock. Date and time is available via 'getDate' and 'getTime' which are structs (see below).
usage example with DCF-Antenna connected to PD4 of an AVR µC and a variable 'tick10ms' which is set true every 10ms (you have to do this yourself in a TIMER-ISR or similar)
#include "dcf77.h"
uint8_t tick10ms = 0;
main()
{
dcf77decoder dcf77;
structtime time;
structdate date;
while(1)
{
if(tick10ms)
{
dcf77.cycledupdate_every_10ms(PIND & (1<<PIND4))
tick10ms = 0;
}
time = dcf77.getTime();
date = dcf77.getDate();
uint8_t hour = time.hour;
uint8_t minu = time.minute;
}
