Hi ! I am using an STM32l0xx and I have some questions about stop mode. First can I choose by software  which exti line are going to wake up the STM. Then can I have a timer interrupt each minute for example but only wake up the STM each 60 minutes, I do 

#low-power-stop-mode #stm32l0

You can do this by using the RTC in stop mode.  There is an example in the STM32 Cube library.

Hi,

I suggest you to have a look to this example under the STM32CubeL0 firmware package:

STM32Cube_FW_L0_V1.8.0\Projects\STM32L073Z_EVAL\Examples\PWR\PWR_STOP_RTC

It shows how to enter Stop mode and wake up from this mode by using the RTC wakeup timer event connected to an interrupt.
