HI,

Sorry about the delay.

Which SDK are you using?

Hi FI,

Thank you so much for the reply,

I am using Codecomposer studio

#include <xdc/std.h>
#include <ti/sysbios/BIOS.h>
#include <driverlib/aon_rtc.h>
#include <driverlib/aon_batmon.h>
#include <time.h>
#include <ti/sysbios/hal/Seconds.h>
Char func;
Char func1;
uint32_t func2;
uint32_t func4;
uint32_t seconds;
uint32_t batt;
time_t t1;
uint32_t t;
struct tm *ltm;
char *curTime;
char seconds1;
char str;
uint8_t str1;
uint8_t str2;
int main()
{
/* Start kernel. */
AONRTCEnable();
func=AONRTCActive();
AONRTCEventClear(AON_RTC_CH1);
AONRTCCompareValueSet(AON_RTC_CH1, 0x5dddcc54);
AONRTCChannelEnable(AON_RTC_CH1);
AONRTCChannelEnable(AON_RTC_CH0);
func1=AONRTCChannelActive(AON_RTC_CH1);
AONRTCCombinedEventConfig(AON_RTC_CH0 | AON_RTC_CH1);
func4= AONRTCCompareValueGet(AON_RTC_CH1);
BIOS_start();
return 0;
}

this code works fine but displaying current timestamp

I follow this method i need to update timestamp continuously by using channel 1 but i dont how to hook the function?

First, in the application .cfg file a hook function is defined for Channel 1:

    var Timer = xdc.module('ti.sysbios.family.arm.cc26xx.Timer');
    Timer.funcHookCH1 = "&myHookCH1";

In main(), Channel 1 is first cleared, a compare (match) value of 4 seconds is set, the channel is enabled:

    AONRTCEventClear(AON_RTC_CH1);
    AONRTCCompareValueSet(AON_RTC_CH1, 0x40000);
    AONRTCChannelEnable(AON_RTC_CH1);

With the above, myHookCH1() will be called when the RTC reaches a count of 4 seconds. At that time, a new compare value can be written for the next interrupt that should occur for Channel 1.

i am also following this link:

i need to display current time and date and also i need to update the date continuously how? can you please help me regarding this
