STM32L0 LPTIM in Stop Mode

Hello everyone. I am a new member to this forum and this is my first use of STM32 products. I'm developing on the STM32L0 Discovery board and building off the LPTIM Timeout Example. Is it possible to start the LPTIM using the LSI and sample the clock while in Stop mode? Can I trigger and interrupt using the LPTIM counter while in Stop mode?

Again, this is my first ST project so I apologize if my description is vague. Any suggestions would be great. Thank you. #lptim #stop-mode

Hi

‌,

 Welcome to STM32 community

I'd highly recommend you to have a look to

 application note witch describe the various modes and specific features of LPTIM embedded in the STM32L0/L4/F7 Series and in the STM32F410.

This application note is provided also with the

embedded software package that contains the three practical applicative use-cases listed below:

• Asynchronous pulse counter in STOP mode.

• PWM generator in STOP mode.

• Timeout wakeup mode.
