STM32C071 Do we need Vref for the internal temperature computation
A new question moved from this thread. In many examples they use the Vref int for the calculation of the temperature. Do I need it for the C0 also or can it be done without?

Resolved! STM32H755 CM7 Reset_Handler Stuck at 'ldr sp, =_estack'
Hello everyone,I am currently working on a project using the STM32H755 microcontroller, and I am facing an issue with the program getting stuck in the `Reset_Handler` during debugging. Specifically, the code halts at the instruction `ldr sp, =_estack...
32F417: Mapping SPI1 to the SWD debug pins PB3-PB5 - how can this work?
One of the AF options on SPI1 is to use the SWD debug pins PB3-PB5.How can this be used in reality?Pretty obviously you can't do SWD breakpoints when SPI1 is thus mapped!But assuming no SWD debugging is needed, and you use SWD just to program the FLA...
Resolved! STM32L0 cannot change PWR_CR_ VOS
Hi, I'm stuck on a problem with setting PWR_CR_VOS on NUCLEO-32 STM32L031K6- I want to select HSI16-PLL as clock source- VDD is 3.3V- FLASH latency is set to 1WSBut I can only set PWR_CR_VOS to RANGE 2 and RANGE 3.RANGE 1 cannot be selected, so I can...
Resolved! STM32F417 to STM32F437 - is the AF mapping identical for pins present in the 417?
This previous thread refershttps://community.st.com/t5/stm32-mcus-products/stm32f4xx-does-going-up-a-package-pin-count-impact-pin-af/td-p/862282The 437 is curiously a very close superset of the 417. Apart from the extra 64k RAM, the only difference i...
Resolved! STM32C071 internal temperature measurement formula
HI, how do I read the temperature value of a STM32C071 ADC and convert it into °C using DMA? I cant find any formula in the datasheet. BR Matthias
STM32U5 DCMI DMA is not working as expected.
Hello, We have developed an image capturing application successfully based on STM32H7xxxx and OV7725 camera. We are now targeting to port the application to target STM32U5xxxx with the same camera. But it looks the DMA doesn't works as expected. T...

RTC LSE not working with VBAT on poweroff
I am working on an STM32 device with TrustZone enabled, and I am using the RTC with backup domain powered by VBAT. My RTC is initially configured while VDD is present, and after power-off, the time is supposed to be retained using VBAT.When I use the...
