Checked PWR settings at startup.Find PWR->SR2 status value 0x00000300.According manual this tellsRegulator in Low Power mode (LPR)Flash memory in power downIs this initiated by Keil/ST-Link debugger?Or are there errors in reference manual of register...

On my workstation I am facing more and more often crashes of ST-Link debug connection.I am using Keil MDK V5.28 (also tried 5.26, V5.34a...) while running debug e.g. with Nucleo STM32G071 (same problem with Nucleo STM32F091...) debugger stops with m...

Debugger stops despite absolut minimal program (s. picture).Any idea ?

Using TIM2_TRGO to trigger DAC. That works.Now want same TIM2_TRGO also to trigger ADC.Is that possible ?Regards Juergen

Sorry, sorry...Forgot to enable clock for peripheral PWR: RCC->APBENR1 |= RCC_APBENR1_PWREN; // Enable clock

Seems that debugger cannot get read access on PWR registers.Tried to set LPMS in PWR->CR1 PWR->CR1 &= ~PWR_CR1_LPMS; PWR->CR1 |= (PWR_CR1_LPMS_2 ); // 1xx, shutdownbut that does not change watch values of PWR-CR1 from 0x00000208...

Made a new project from scratch. Same - bad - result

One has to set ADSTART bit, no matter if software triggered or hardware triggered...Depending on the EXTEN [1:0] configuration bits, a conversion either starts immediately (software trigger configuration) or once a hardware trigger event occurs (har...

Still no TIM2 trigger of ADC.DAC is running ok: TIM2 is running and triggers the DAC. DAC requests DMA and finally generates a sine wave of 200 Hz.ADC in standstill with calibration value in DR. No triggerAny idea regarding ADC triggering ?Regards J...
