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! ETH->MACISR TSIS unstoppable?
Hello there, I'm playing with the NUCLEO-H743ZI2 board and having difficultis with PTP. When TSIE (MACIER is set the interrupt is getting retriggered endlessly. I've tried to clear TSIS by reading both MACISR as well as MACTSSR (TXTSSIS bit set). The...
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! JTAG DEBUG_JDI conflicts with FMC_NBL1 byte enable
My target is a 144 pin version of the STM32H5.I would like to implement both a JTAG and a FMC interface.More specifically, a 24-bit muxed-PSRAM.And I would like to output the Byte enable signals.However on this package size, there is only one possibl...
Resolved! STM32H7S7L8H6: How to connect the VDD50USB pin when USB is not in use?
Hello Team, One more query is there. We are not using USB. In STM32H7S7L8H6 pin D9-VDD50USB is there. So, can we connect it with 3.3V supply? Thanks & Regards, Jignesh Karena
Does enabling MSBFIRST change the position of the parity bit in the USART frame?
Hi everyone,I’m working with an STM32L5 USART and trying to clarify a point about parity vs. MSB-first transmission.From the reference manual (USART parity control / frame formats), when parity is enabled the frame formats are shown as:M=00, PCE=1: S...
STM32F446 EXTI GPIO interrupt not triggering
Hello, I’m working with an STM32F446 and have configured GPIOB pin 12 as an EXTI input. After initialization and before entering the main while loop, I call a function that blocks program execution(what I mean by blocking : I have a test that stands ...
ISSUE with STM32L051C8T6
Dear ST Team,我用usb转ttl单独对4g模块发at，回复消息是正常的，单独模拟给单片机发数据，回应的数据也没有丢字符，就是4g模块跟单片机之间通信的时候存在问题When I use a USB-to-TTL adapter to send AT commands to the 4G module alone, the responses are normal. When I simulate sending data to the microcontroller alone, th...
