Good day Sirs, I have the following issue:
MCU: STM32L152ZE
Software library: Standart Peripherial Library (supporting old project)
I have need to count external pulses on PB3 input using TIM2 CH2.
Pul...

Good afternoon, I have deal with STM32L152ZD RTC in alarm mode( alarm B), I need to make it interrupt every rtc_period seconds. Clocking source is LSE with frequency 32768 Hz, RTC working good, but interrupts ...

Good afternoon, I am trying to init UART5 on STM32L152 and it is work wrong.
In the end of the
sw_uart5_init function
0xAA (0b10101010) value issent to the UART5 data register. The transmission result, r...

Dear
JW,
following your recomendation I have created minimal project and it works, timer conts external pulses... but counts with pulses loss at start.
EXTERNAL PULSES ON PIN: 6 11 16 21 26 251
TIMER COU...

Thanks for attention,waclawek.jan!
Here the read values of TIM2 and GPIOB registers from debugger.
TIM2 DMAR register value is a surprise. DMA not used in this project, blank project - only timer init.

One problem has been detected, we have to use some kit of masks,
RTC_AlarmMask_DateWeekDay
make interrups available.
RTC_AlarmStruct.RTC_AlarmMask = RTC_AlarmMask_DateWeekDay;
Now i...

Problem has been detected: ^)
// [5] Turn on alarm mask, RTC will make an event each time it count to the seconds value in RTC_AlarmTime.
// RTC_AlarmMask_Seconds not working - right way is to use R...
