Arduino for STM32

In fact HAL_LPTIM_MODULE_ENABLED is not enabled by default. you can add an hal_conf_extra.h file with:

#define HAL_LPTIM_MODULE_ENABLED

to enable it.

In this archive, you will get a port of a STM32Cube project for L4:

Even with including this file the definitions aren't reconized....

try the normal Hardware Timers

those works well and doesn't use much power

In situations like this, you should think about a few questions.

1. Are there other solutions?
2. Is the timer able to wake up the chip?
3. What's the clocking arrangement?
4. How big or small is the desired interval?
5. Given 3 and 4 above, can the timer do it in one shot or you need to wake up ...

I need in stop mode to :
Wait x second
Toggle a pin
Wait x second
Toggle a pin

But i can't use RTC beacause it is already used for the LoRaWAN part (STM32WLE55).

It is not hard . If it was just in STM Cube IDE it would be easy but here the LPTIM don't seems to be simple to implement

Thanks you for the anwser

Do you have a small example of a HAL implementation for LPTIM that could work with stm32duino

Beaucause even with copying the code of the HAL generated in STM32 IDE i got these errors:


LPTIM_HandleTypeDef hlptim1;

static void MX_LPTIM1_Init(void)
{

/* USER CODE ...

Hello,

When i try to use LPTIM1 of a Nucleo 32 l031k6 i got errors about the fact that TIM_TypeDef can't take the word "LPTIM1"

Is there a way to use LPTIM with stm32duino or i need to tuse HAL ?

Thanks
