Hi,I am using stm32L431 and (32.768KHz ±20ppm 12.5pF 70kΩ) as LSE.Every day the time is update by internet, but in some cases, the clock shifting about 5 minutes.It occur aroung 2 times to week. what is probably happening?Binary data format and Alar...

Hi,I am using stm32L431 and trying to use LPTIM to count pulses.When I call HAL_LPTIM_Counter_Start() return HAL_TIMEOUT in if (LPTIM_WaitForFlag(hlptim, LPTIM_FLAG_ARROK) == HAL_TIMEOUT) {  return HAL_TIMEOUT; }But if I comment this part of function...

Hi,I am using stm32L431, in the documentation says that when using LPTIM pulse counter the 5 first pulses is lost, after this the counter works fine. But in my project this situation is not acceptable, because in some cases I use less than 5 pulses.I...

Hi,I am using stm32l431 and work with LPTIM in stop2mode. When the mcu wake up after stop mode, i2c stop working, so I need to restart mcu.It's strange because in some cases the i2c work in the next 3 wake up, but after this dont work anymore. Should...

Hi, I am using stm32431. I config LPTIM and call HAL_LPTIM_Counter_Start() but return HAL_TIMEOUT and no pulses is count. When I change HAL_LPTIM_Counter_Start() function putting 'HAL_OK' to be return forced, the pulses is counted normally, but not i...
