Disable timer1 interrupt

JN5169

Hello,

I added a DIO interrupt switch to the demo, sending DIO level from End Device to Coordinator.

Every 5 seconds, timer1 interrupt wakes up to poll. My data only travels from End Device to Coordinator.

I don't need poll request, nether timer1/timer0 interrupts.

I need DIO interrupt in sleep mode.

I can't find how to remove timer1 (and timer0) interrupts and keep DIO interrupt still working.

If I remove timer1 initialisation (APP_vInitResources => ZQ_vQueueCreate(&zps_TimeEvents, TIMER_QUEUE_SIZE, sizeof(zps_tsTimeEvent), (uint8*)asTimeEvent);

I get APP: Unexpected event in E_NETWORK_JOIN - 21

If I go deep in removing interrupt init, DIO interrupts are disabled too.

Which part of code should I remove, please ?

Regards,

Pierre

Finally, I filtered u32IntSource to process DIO interrupts.

Timer1 is still a mystery, as it always interrupt in

void APP_isrSysCon (void)
{
    /* clear pending DIO changed bits by reading register */
    uint32 u32IntSource = u32AHI_DioWakeStatus();
    uint8 u8WakeInt = u8AHI_WakeTimerFiredStatus();
    if (u8WakeInt & E_AHI_WAKE_TIMER_MASK_1)
    {
        /* wake timer interrupt got us here */
        DBG_vPrintf(TRACE_APP_SYSCON, "APP: Wake Timer 1 Interrupt\n");
        PWRM_vWakeInterruptCallback();
    }

on wake up initiated by

PWRM_eScheduleActivity(&sWake, SLEEP_TIME, vWakeCallBack);

I don't understand where Timer1 remaining time is set. In the other hand, Timer0 never interrupt.

Hi Pierre,

Are you sure that is entering the APP_isrSysCon?

That API is defined if you are only using the JN517X.

I am confused, did you disable the timer yet?

Hi Mario,

Yes, I am entering APP_isrSysCon thanks to

#if JENNIC_CHIP_FAMILY == JN517x
void APP_isrSysCon ( uint32 u32Device, uint32 u32ItemBitmap )
{
// Disabled code
}
else
void APP_isrSysCon (void)
{
// Runs here
}
#endif

Timer is still running. Now I am dealing with interrupt priorities as polling and button press interrupts collides over RF bus.

Regards,

Pierre
