#include <Rtc_Pcf8563.h>
//init the real time clock

void setup()
{

settime(15, 8, 10, 4, 15, 57, 36);//Year, month, day, week, hour, minute and second
}
void loop()
{
//both format functions call the internal getTime() so that the
//formatted strings are at the current time/date.
Serial.println("CODE_1:");
Serial.print(rtc.formatDate());//Acquire data
Serial.print(" ");
Serial.println(rtc.formatTime());//Acquire time
Serial.println("CODE_2:");
Serial.print("20");
Serial.print(rtc.getYear());//Acquire year
Serial.print("/");
Serial.print(rtc.getMonth());//Acquire month
Serial.print("/");
Serial.print(rtc.getDay());//Acquire day
Serial.print(" ");
Serial.print(rtc.getHour());//Acquire hour
Serial.print(":");
Serial.print(rtc.getMinute());//Acquire minute
Serial.print(":");
Serial.println(rtc.getSecond());//Acquire second
delay(1000);
Serial.print("\r\n");
}
void settime(int _year, int _month, int _day, int _week, int _hour, int _min, int _sec)
{
//clear out the registers

//set a time to start with.
//day, weekday, month, century(1=1900, 0=2000), year(0-99)

FAQSome of the example codes that use the RTC module doesn't compile or gives an error! There is an issue with the incorrect and outdated software library included in the Microduino software package. To fix it, please follow the guide below:
