Resolved! Backup registers - using them to detect power issues: Will this work?

Using a STM32F091.I was thinking whether one could detect certain kind of boot / power issues where the VDD would be briefly interrupted, by buffering the VBAT with a sufficiently big capacitor, separated by a diode with low Vforward from VDD, so the...

Resolved! How to control main while loop using EOC flag of ADC in continuos mode? Apparently ADC_SAMPLETIME_**** is not affecting ADC sampling time

For a given application I am trying to control the main loop speed thorugh the ADC sampling rate. My objective is targeting a fast embedded control application so I plan to go in the 100kHz-10MHz range (yes, I am aware of the STM32H7 limitations for ...

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 ?
