CC3200 wake up

Other Parts Discussed in Thread: CC3200SDK, CC3200

Hello,

I would like to know how to recognize the wake up source.

I wake the system by two ways :

First with GPIO

Second by timer.

How the system knows its wake up source ?

Many thanks

    You can refer to the "idle_profile" example in CC3200SDK where the wake up source (GPIO / Timer / host irq) is printed over UART whenever CC3200 wakes up.

    Hi Vaibhav,
    Thanks for your answer.
    I try to use PRCMHibernateWakeupCauseGet() but the return value is always "0",Instead of the source values (PRCM_HIB_WAKEUP_CAUSE_SLOW_CLOCK or PRCM_HIB_WAKEUP_CAUSE_GPIO)
    The example you refer use osi but I don't.
    Please have you a light for me ?
    Best Regards
