Grove RTC base on PCD85063TP

Grove - High Precision RTC_PCF85063TP

Grove - High Precision RTC is based on PCD85063TP, it's usage is almost the same with ds1307.

Grove - High Precision RTC

Grove - High Precision RTC based on the clock chip PCF85063TP which is a CMOS Real-Time Clock (RTC) and calendar optimized for low power consumption. An offset register allows fine-tuning of the clock. All addresses and data are transferred serially via the I2C bus and the maximum bus speed is 400 kbit/s.

Methods

• void startClock(void);
• void stopClock(void);
• void setTime(void);
• void getTime(void);
• void setcalibration(int mode, float Fmeas);
  
  • mode 0 - offset is made once every 2 hours
    
  • mode 1 - offset is made once every 4 minutes
    
  • Fmeas - real clock frequency you detcet
    
    
• uint8_t readCalibrationReg(void);
  
  • Read offset register at 0x02
    
    
• uint8_t calibratBySeconds(int mode, float offset_sec);
  • offset_sec - need a long time running RTC and work out the offset by one second
• void reset();
• void fillByHMS(uint8_t _hour, uint8_t _minute, uint8_t _second);
• void fillByYMD(uint16_t _year, uint8_t _month, uint8_t _day);
• void fillDayOfWeek(uint8_t _dow);
