What is the value of LPTIM_CNT after MCU RESET?

Hello ST microelectronics support team.I'm developing an IOT application using the STM32WLE5CC for gas measurement. To measure the pulses I'm thinking of using the LPTIM, but I have a doubt.In topic 26.4.14 of the RM0461 reference manual, I became aw...

Resolved! STM32 ADC?

Good morning......I am using the ADC with 2 channels (Ch 9 and Ch 10). I am using an LPTIM to take these samples every 15ms. I have the ADC callback (HAL_ADC_ConvCpltCallback) to interrupt on 'End of sequence of conversion' (per .ioc --- or so I thin...

Resolved! STM32WLE5JB doesnt exit from stop mode with LPTIM.

I'am using STM32WLE5JB with LOWPOWERMODE_STOP(0,1,2) to deacrease power consumption. Although I configured LPTIM with LSE for 2 sec period to wake up, device doesnt exit from stop mode. I tried LPTIM with LSI the result was same. Here is My code LPTI...
