You can do it in hal_sleep.c

Hi YK

I just go through that hal_sleep.c but i didn't get it. So i can use this function (void halSleep( uint32 osal_timeout )) to set the sleep time,
and also can i call it from any where in the application layer.

Thanks

Go to check HAL_SLEEP_DEBUG_LED in halSleep().

hi yk chen,
i put a break point at ,but it is not hitting that break point, i am using simple generic_app code. in compiler option i am using following things,
FEATURE_RESET_MACRO
ewarm
NWK_AUTO_POLL
POWER_SAVING
ZTOOL_P1
xMT_TASK
xMT_SYS_FUNC
xMT_ZDO_FUNC
xLCD_SUPPORTED=DEBUG
CC2538_USE_ALTERNATE_INTERRUPT_MAP=1
NV_RESTORE
HAL_SLEEP_DEBUG_LED
HAL_LCD=FALSE
HAL_SPI=FALSE
HAL_LED=FALSE
HAL_KEY=TRUE
NV_INIT

is there anything else i want to put or remove in compiler options, and do i need to call any functions that are present in hal_sleep.c
so please help me in setting sleepy end_device.

thanking you

When debug, it won’t go to sleep mode. You have to let application free run to see it works.

hi yk chen, thanks for the reply
i left it in free run,even though its not working(i know it as its not blinking the led even though i mention HAL_SLEEP_DEBUG_LED) is there any thing else i want to do in compiler option or in the code

thanks

If you define HAL_SLEEP_DEBUG_LED and POWER_SAVING enable, LED3 on CC2538DK will turn off when device enters sleeping mode and LED3 will turn on when device are not in sleeping mode.

hi yk chen,
i want to know what is the use of the function void halSleep( uint32 osal_timeout ).

When there’s nothing to process in osal task queue, osal will call halSleep to make device enter sleeping mode.

thanks for the reply yk chen,
in halSleep( uint32 osal_timeout ) funtion , who is giving osal_timeout value. and i want know where can we adjust sleep duration or it will be fixed(i mean hard codded some where else)

Different timer event will set different timeouts and osal will take care of it. You shouldn’t change it.

so hear i want to keep sleep duration for 1hr,so how the timer event will know that i want to set the sleep duration for 1 hr

is there any example code of sleep mode used for only led blinking(during sleep: LED_OFF,wakeup: LEDON)

In halSleep() of Z-Stack hal_sleep.c, you can check “HAL_SLEEP_DEBUG_LED” which does similar thing.
