Function Documentation

void dcf_get_time (  struct snt_time_stamp *  time  )

Get current time. Parameters: time  Structure receiving the current time and date. Definition at line 321 of file dcf77.c.

void dcf_init (  void   )

Initialize dcf77 receiver harware and timer. Also registers TimeKeeper object. After calling this function the clock starts running from 01.01.2000 00:00:00. When a valid time telegrams is received the clock is adjusted according to these telegram. Definition at line 242 of file dcf77.c. Referenced by main().

void dcf_process (  void   )

Process received time telegrams. Should be called periodically from the main loop but not from a timer ISR since the implementation is not thread save. Definition at line 269 of file dcf77.c. Referenced by main().
