Hello all 

I'm working on STM32L152RE nucleo board. I ain't able to integrate Timer  in low power mode .

so is it possible to work with timer and low power mode in STM32L152RE  simultaneously?

If yes, which timer is used?

#timer-interrupts #interrput #stm32l152re #low-power-mode #timer #stm32

Hello

pratap.lovekush

‌,

STM32L152 does not have LPTIM peripheral (Low-Power Timer) which can wake up core from different low-power modes.

General timers can wake up core, but not from all sleep modes. There is also RTC option which can wake up device from different sleep modes. What is the sleep mode you are interested in?

In application noteAN3193 you can see low-power overview of STM32L1xx.

Best regards,

Tilen

Hello Tilen ,

Thanks for the support. 

I'm trying to use standby mode or stop mode.

Could you assist which mode is more power saving and does that mode support timer?

Best Regards
