How to use LPTIM in wakeup mode? L432KC

Michael Gross

Hello. I would like to use low-power timer to wakeup from stop mode (1 or 2).

My model is: start LPTIM, generate PWM from one TIM (general-purpose), wait for timeout in stop mode, then start LPTIM again, generate signal etc.

I used demo for LPTIM (timeout), but it doesn't work (no go back to LPTIM handler, only enter stop mode).

Thank you for your answers!
