Resolved! STM32F405: ISR vector table in CCM?
ISR vector table in SRAM works, but not in CCM. Is this possible? If not, what is the theory behind it? Vector fetching done through I-Bus or S-Bus?

How do you setup ITR0
I see that those ITR0 .. 4 are connected somehow to timers you can use it as timer trigger.How do you set it up working. Can somebody provide sample code ?I want faster timer to control (start, stop) with slower time. I have spent a few weeks experim...
ADC trigger with PWM and reading voltage on its state
Hi everyone,I have a question about ADC trigger. I have to generate a PWM 1.1KHz and read the avarage voltage of ADC pin accoding to the On/Off state of that PWM. How can I make it.? I enclosed an image about it.
NUCLEO-H743ZI availability? - Q to STM team
Dear STM team,we use and love your STM32H7. We would need approx. 50 NUCLEO-H743ZI, but no way to order this amount.It looks like, the H7 NUCLEO is not available (in the US) "anymore".What is the status of your H7 chips, esp. NUCLEO boards?Is my gues...
My PVD (Programmable Voltage Detector) don’t work
Hi.I want my MCU (STM32F107VCT6) to generate an interrupt when the Vdd is below (e.g.) 2.9V. I have implemented the following init-code:PWR->CR = PWR_CR_PLS_2V9; // 2.9V mcu_reg = PWR->CR; PWR->CR |= PWR_CR_PVDE; // Bit 4 PVDE: Power voltage d...
How to store configuration values on a STM32L432
Hello. I would like to store specific configuration values on several STM32L432. They are related to network configuration parameters (network ID, element ID, number of elements in the network, etc.) and It should be changed sometimes. They are eleme...
How the font size can be Increased?
I upgraded the STM32CubeMx to 5.0, today. But it is very difficult to read the User Interface and Text in the Program. How i can get bigger fonts?I am developing programs with STM32H753 (my own PCB), and H743(nucleo 144) board... Is there any bigger ...

Resolved! Can't get TIM4 TOGO to start ADC3 conversions on STM32F7DISCOVERY board.
I'm trying to get TIM4_TOGO output to start conversions on ADC3 on a STM32F7 DISCOVERY board.I've attached main.c. I use a GPIO output toggle with oscilloscope to detect code execution and timing. I can see the toggle from the TIM interrupt handler, ...
