CC2538: Use of RTC

Raghunandana DS

Part Number: CC2538

Hi,
Iam trying to set the RTC in CC2538, but it was not at all starting, I was always getting same time what I was set. For further detail please check my code

  // Setting Real time //
  UTCNewTime->seconds = '0';
  UTCNewTime->minutes = '30';
  UTCNewTime->hour = '11';
  UTCNewTime->day = '21';
  UTCNewTime->month = '8';
  UTCNewTime->year = 17;
  
  NewTime = osal_ConvertUTCSecs(UTCNewTime);
  printf("set time = %d\n", NewTime);

  osal_setClock(NewTime);

  while(1){

  CurrentTime = osal_getClock();
  printf("cur time = %d\n", CurrentTime);
  
  osal_ConvertUTCTime(UTCCurrentTime, CurrentTime);

  }

I was always getting set time has new time,

Thanks,
Ragards,

Try to call osalTimeUpdate in front of osal_getClock.

Hi,
Thank you its working fine as timestamp, But I can't read it correctly. I am trying like this to print the read value.
/////////////////////////////////
osalTimeUpdate();
CurrentTime = osal_getClock();
printf("new=%d\n", CurrentTime);

osal_ConvertUTCTime(UTCCurrentTime, CurrentTime);

printf("y=%d\n", UTCCurrentTime->year);
printf("m=%c\n", UTCCurrentTime->month);
printf("d=%c\n", UTCCurrentTime->day);
printf("h=%c\n", UTCCurrentTime->hour);
printf("m=%c\n", UTCCurrentTime->minutes);
printf("s=%c\n", UTCCurrentTime->seconds);
/////////////////////////////////////////////////////////////

Timestamp is printing fine, fine order wise printing unknown char's.

I couldn't understand your question well. Please elaborate.

After I got the time stamp by calling, "CurrentTime = osal_getClock();" I want to see the described time like year, month, day, hour, min and sec
so I am calling "osal_ConvertUTCTime(UTCCurrentTime, CurrentTime);" and trying to print the converted time like below
printf("y=%d\n", UTCCurrentTime->year);
printf("m=%c\n", UTCCurrentTime->month);
printf("d=%c\n", UTCCurrentTime->day);
printf("h=%c\n", UTCCurrentTime->hour);
printf("m=%c\n", UTCCurrentTime->minutes);
printf("s=%c\n", UTCCurrentTime->seconds);

But getting unknown information, Finally I want see the time in normal format.

Hi Chen,
Increase in 1 sec increment the timer by 2 count.
I mean I set '0' sec If I read after 10 sec's I was getting 20 sec, why it was like this

I would suggest you to use a timer event to test osal timer instead of putting all those code in a while loop.
