void setClkOutputFrequency(output_frequency frequency)

Sets output signal frequency.

Parameters:

• output_frequency frequency - selected frequency

Valid values :

• CLKOUT_32768_Hz - 32768Hz
• CLKOUT_1024_Hz - 1024Hz
• CLKOUT_32_Hz - 32Hz
• CLKOUT_1_Hz - 1Hz

Time getTime()

Reads current time and returns it as a structure.

Returns: Current time encoded inside Time structure.

Time structure :

struct Time
{
  uint8_t year;     //year
  uint8_t month;    //month
  uint8_t day;      //day
  uint8_t weekday;  //weekday (1-7)
  uint8_t hour;     //hour
  uint8_t minute;   //minute
  uint8_t second;   //second
};

bool checkClockIntegrity()

Check clock integrity.

Returns: true if clock is valid. If not returns false.
