LPTIM cnt Initialize

[MWisi.1]

I am using the low power timer (LPTIM), but i need to initialize the timer value to 30000 before start the counting.

Is it possible ?

Thank you!

Yes:

LPTIM1->CNT = 30000;

You can do this prior to using HAL_TIM_Base_Start() HAL_LPTIM_*_Start if you're using HAL since the function doesn't touch the counter.

hi @TDK​ 

I had done

LPTIM1->CNT = 30000;

But, i hadnt used the HAL_TIM_Base_Start()!

I will try then tomorrow this sequence!

LPTIM1->CNT = 30000;

HAL_TIM_Base_Start(&s_TimerInstance);

Can i always repete this sequence in at any point in the program and repeat it ?

Because i will receive a LoRaWAN message that contains this LPTIM1 value.

I will have to change the LPTIM1 many times

Thanks

Yes you can change the counter during execution. If you’re interested in the details, read through the timer section of the reference manual.

Did you see that is not writable the lptim counter ?
