watchdog timer ISR not working

moshc_4060821 · ‎Apr 02, 2019

i am working with Psoc4 Ble pioneer kit.

i want to generate a WDT based interrupt after every hour. so to do that i have i have used global signal component.

this is my code

CY_ISR(WDT_ISR_handler)
{
    WDT_ISR_ClearPending();
}
int main(void)
{

    HW_Init();

    /* Starts RTC component */
    RTC_Start();
    /* Set RTC time update period */
    RTC_SetPeriod(1u, SYSTICK_EACH_1_HZ);

    RTC_ClearAlarmStatus() ;
    RTC_SetAlarmHandler( alarm_handler ) ;
    RTC_SetAlarmMask( RTC_ALARM_SEC_MASK ) ;

    WDT_ISR_StartEx(WDT_ISR_handler);



    for(;;)
    {

    }
}

please find attached screen shots for WDT2 clock configuration.(currently i am testing it with only 4 seconds)

so my problem is first time interrupt is generated after 4 seconds but then it could not clear and the pending register or something.

please guide me.

hi

i have solved the problem.

this is my code.

CY_ISR(WDT_ISR_handler)
{
      CySysWdtClearInterrupt(CY_SYS_WDT_COUNTER2_INT);
}
int main(void)
{
    HW_Init();

    /* Starts RTC component */
    RTC_Start();
    /* Set RTC time update period */
    RTC_SetPeriod(1u, SYSTICK_EACH_1_HZ);

    RTC_ClearAlarmStatus() ;
    RTC_SetAlarmHandler( alarm_handler ) ;
    RTC_SetAlarmMask( RTC_ALARM_SEC_MASK ) ;
     /* Enable WDT0 counter */
    CySysWdtEnable(CY_SYS_WDT_COUNTER2_MASK);   // WDT=PeriodicTimer
    WDT_ISR_StartEx(WDT_ISR_handler); // Start ISR for pin toggle
    CySysWdtEnable(CY_SYS_WDT_COUNTER2);
    for(;;)
    {

    }
}

thanks for helping.
