Hi,

I just got a Nucleo STM32L031K6 board and start playing with STM32Cubemx.

For my project I need to use the low power timer LPTIM to trigger another timer (e.g. TIM2) but I have no clue how to do this.

Could someone help me with some hints please? (an example code would be really nice since I'm really new to STM32 !)

Thanks,

Bien

    This is posible only by external loop, but this will not work in loW power modes...
