delay in zstack event

Do you try to use interrupt for key trigger?

Hi YiKai Chen,

I have done only below changes. 

I have changed onboard.c as in Power management documents. 

else // !OB_COLD
{
/* Initialize Key stuff */
HalKeyConfig(HAL_KEY_INTERRUPT_ENABLE, OnBoard_KeyCallback); 
}

I have put a break point in key int ISR.

If I press SW1, Execution will come to below key ISR. 

INTERRUPT_KEYBD()
{
#if (HAL_KEY == TRUE)

#ifdef POWER_SAVING
/* Must allow key interrupt to cancel sleep */
__low_power_mode_off_on_exit();
#endif

/* Read the key before it gone */
HAL_KEY_INT_KEYS(halIntKeys);

/* Clear depending interrupt */
HAL_CLEAR_KEY_INT();

/* A key is pressed, let HalKeyPoll routing handle the keys at a later time */
osal_start_timerEx( Hal_TaskID, HAL_KEY_EVENT, 10000);
#endif /* HAL_KEY */
}

Did you ask this or something else?

Yes, that's what I am asking. Do you try to reduce 10000 in osal_start_timerEx( Hal_TaskID, HAL_KEY_EVENT, 10000)  to see if it response faster.

Hi YiKai Chen,

Yes. Now Thats working fine. Thanks. 

I have another doubt. I have enabled the RTC. For each 5 min, I have send some data to coordinator. 

RTC ISR:

#pragma vector=RTC_VECTOR
__interrupt void RTC_ISR(void)
{
switch(__even_in_range(RTCIV,16))
{
case RTC_NONE: // No interrupts
break;

case RTC_RTCRDYIFG: // RTCRDYIFG
break;

case RTC_RTCTEVIFG: // RTCEVIFG
HAL_TOGGLE_STATLED3();
Sample_Min++;
if(Sample_Min == 5)
{
Sample_Min = 0;
osal_set_event(SampleApp_TaskID, READ_EVT);
__bic_SR_register_on_exit(LPM3_bits);
}

break;

Here also I get a delayed response for READ_EVT occurrence. 

I think problem in hal_sleep function. 

/* set MSP430 power mode, global interrupt will be enabled in the macro */
HAL_SLEEP_SET_POWER_MODE(halPwrMgtMode);
/* wake up from sleep in ISR */

HAL_SLEEP_DISABLE_INTERRUPTS();

/* disable sleep timer interrupt */
HAL_SLEEP_TIMER_DISABLE_INT();

if (timeout != 0)
{
/* Calculate timer elapsed only if timer sleep */
halAccumulatedSleepTime += halMacTimerElapsed( &timeout );
}
else
{
/* Restart timer */
HAL_MAC_SLEEP_TIMER_RESTART();
}

/* Process keyboard "wake-up" interrupt, exit while loop if key interrupt */
if ( HalKeyExitSleep() || timeout == 0 )
{
break;
}

They do some exit sleep using key interrupt. 

How Can I do this things for RTC or any other interrupt? 

I have gone through the HalKeyExitSleep() . But I can't follow. 

if I am telling correct problem, Please explain.

Try to replace __bic_SR_register_on_exit(LPM3_bits); in case RTC_RTCTEVIFG: with

#ifdef POWER_SAVING
/* Must allow key interrupt to cancel sleep */
__low_power_mode_off_on_exit();
#endif

Hi YiKai Chen, 

I was changed. But The problem is same. 

/* Process keyboard "wake-up" interrupt, exit while loop if key interrupt */
if ( HalKeyExitSleep() || timeout == 0 )
{
break;
}

I think we need to exit from while loop in hal_sleep function. 

And Need to add HalRTCExitSleep() like below. I don't write any coding for HalRTCExitSleep function. 

If I am telling right , you will tell how to write that function. 

/* Process keyboard "wake-up" interrupt, exit while loop if key interrupt */
if ( HalKeyExitSleep() || timeout == 0 || HalRTCExitSleep() )
{
break;
}

Another question:

What is timeout in above if statement?

I suppose my suggestion should work. Can you show me what's revision you made in __interrupt void RTC_ISR(void)?

Hi YiKai Chen,

This is RTC ISR. This function present in sampleapp.c. 

#pragma vector=RTC_VECTOR
__interrupt void RTC_ISR(void)
{
switch(__even_in_range(RTCIV,16))
{
case RTC_NONE: // No interrupts
break;

case RTC_RTCRDYIFG: // RTCRDYIFG
break;

case RTC_RTCTEVIFG: // RTCEVIFG
HAL_TOGGLE_STATLED3();
Sample_Min++;
if(Sample_Min == 05)
{
Sample_Min= 0;
osal_set_event(SampleApp_TaskID, READ_EVT);

#ifdef POWER_SAVING
/* Must allow key interrupt to cancel sleep */
__low_power_mode_off_on_exit();
#endif

}

break;
case RTC_RTCAIFG: // RTCAIFG
break;
case RTC_RT0PSIFG: // RT0PSIFG
break;
case RTC_RT1PSIFG: // RT1PSIFG
break;
case 12: break; // Reserved
case 14: break; // Reserved
case 16: break; // Reserved
default: break;
}
}

Note:

Then Why do they using HalKeyExitSleep(). ?

Hi YiKai Chen, 

Again the problem in key interrupt also. 

-DPOLL_RATE=5000 - No delay

-DPOLL_RATE=10000 - Small amount delay to trigger the event

-DPOLL_RATE=60000 - More delay to trigger the event
