I'm using STR912FA44 for our project.

i'm not able to use RTC's periodic interrupt. when it is enabled CPU gets reset. Pls can anybody help me? my initialization routine is as follows: void InitRTC (Int32U IntrPriority) { // Enable RTC clocks SCU_APBPeriphClockConfig(__RTC, ENABLE); // RTC Deinitialization RTC_DeInit(); RTC_PeriodicIntConfig(RTC_Per_2Hz); RTC_ITConfig(RTC_IT_Per,ENABLE); // VIC configuration VIC_Config(RTC_ITLine, VIC_IRQ, IntrPriority); VIC_ITCmd(RTC_ITLine, ENABLE); }

Dear chandrakant.bhor,

I also using same MicroC., I also tried its RTC. Its initialisations was as follows. In following example I have used Alarm Interrupt & it was working fine. I think You are not initialised RTC completely. void fnInitRTC( void ) { RTC_DATE stRTCDate; RTC_TIME stRTCTime; RTC_ALARM stRTCAlarm; //Initialize Date Structure stRTCDate.century = 20; stRTCDate.year = 99; stRTCDate.month = 12; stRTCDate.day = 31; stRTCDate.weekday = 5; //Initialize Time Structure stRTCTime.hours = 23; stRTCTime.minutes = 59; stRTCTime.seconds = 45; stRTCTime.milliseconds = 00; //Initialize Alarm Structure stRTCAlarm.day = 1; stRTCAlarm.hours = 00; stRTCAlarm.minutes = 00; stRTCAlarm.seconds = 15; RTC_SetDate( stRTCDate ); RTC_SetTime( stRTCTime ); RTC_SetAlarm( stRTCAlarm ); //Enable Alarm Interrupt RTC_ITConfig( RTC_IT_Alarm, ENABLE ); VIC_Config( RTC_ITLine, VIC_IRQ, 10 ); VIC_ITCmd( RTC_ITLine, ENABLE); //Enable Alarm RTC_AlarmCmd( ENABLE ); }//fnInitRTC All the Best Sachin Bhujbal
