How to use the HAL_RTCEx_SetWakeUpTimer_IT function with WakeUpAutoClr argument?

[CYou.1]

Hello,

I'm using STM32L4P5 and try to use HAL_RTCEx_SetWakeUpTimer_IT function.

For example, I want to make a wake up timer have 30 minutes.

What value should I use for the WakeUpAutoClr?

HAL_RTCEx_SetWakeUpTimer_IT(&hrtc, 1800, RTC_WAKEUPCLOCK_CK_SPRE_16BITS, ?);

Thanks,

Calvin

Hi @CYou.1​ ,

Did you have a look at the STM32CubeL4 ? Did you check the RTC and TIM examples ?

Best Regards,
