Due and Built in RTC? Anyone Know About clock() ?

Hardware Arduino Due
5

Hi, I was looking for making the due RTC work too, so I tried to do it with some register manipulation but the IDE tells me that the registers are not declared... Since I'm not very good, If someone could take a look at my code I could be nice.

void setup()
{
  Serial.begin(9600);
  if(RTC_WPMR==B01010010010101000100001100000001) bitSet(RTC_WPMR,0);// dissable Write protection
  bitSet(RTC_CR,0);  // request time and date update
  while(bitRead(RTC_SR,0)!=1)  //wait for acknowledge for update 
  {}
  bitSet(RTC_SCCR,0);
  RTC_MR=0; //Set hour mode to 24h
  RTC_TIMR=B00000000001000110011000000110000;// set time: 23:30:30
  bitClear(RTC_CR,0);//exit programing mode
  delay(5000);
}
void loop()
{
  rtcToTime(RTC_TIMR);
  delay(10000);
}
void rtcToTime(int rtcTime)
{
  int h=rtcTime>>16;
  int m=(rtcTime>>8)&B000000000000000001111111;
  int s=rtcTime&B00000000000000000000000001111111;
  Serial.print(h);Serial.print(':');Serial.print(m);Serial.print(':');Serial.println(s);
}

Thanks :slight_smile:
