Resolved! Understanding Backup Domain & what happens when (RTC, backup registers, power cycle)

Hello,I was reading the reference manual of the STM32F091, in particular the RTC chapter.Then I looked at what the CubeIDE generated (set all to LL, not HAL) init code does.So it has this function SystemClock_Config() where all clocks are configured....

Resolved! Issue in debug mode when use Uart

Hello,I'm creating application with STM32F072, with ADC DMA, USB, Timers and Uart.Last one is used to communicate with PC but i verify a strange behavior.First of all general information:generating this software with STM32cubeMx. using IDE openstm32p...

Resolved! Hello, what are these registers : EXTI_D1, EXTI_D2 EXTI->PR1, EXTI->PR2, EXTI->PR3 EXTI_Dn->PR1, EXTI_Dn->PR2 (n= 1 or 2) I saw them but I didn't find any reference. How could register EXTI_CPUPR1 be read ?

Resolved! GPIO output is running slower than clock frequency

HiI'm trying out stm32h743 now, and try to make output signal from GPIO.I've set same frequency on F429 & H743 with same code. However, The the signal much slower(longer) in H743.F429 400nsH743 4000ns (well... my purpose is to shorten the l...
