Resolved! STM32F070F6P6 is not connecting to st-link
I have recently ordered my custom board from JLCPCB with STM32F070F6P6. When the board arrived to me, I tried to connect the CPU to ST-LINK V2, but it would not connect. I have checked all the connections on the board and everything seems to be good....
Resolved! Overshoot spikes on SD card interface with STMH743BIT
I'm getting bad overshoot and undershoot spikes on an SD card interface. The spikes are so bad that 1/300 large (2MB) file writes fails, and it's damaging the SD cards so that a card that has been subjected to these spikes will continue to fail after...

Hi,I'm working on a USB Mass Storage Class (MSC) application using the STM32U5 series. I have a working firmware that correctly enumerates as a USB MSC device on STM32U5G9J-DK2 - Windows detects it and loads the built-in USBSTOR.SYS driver as expecte...
STM32H735G-DK STMOD+ Pin4 as GPIO
Hello,I will need some help to determine if STM32H735G-DK STMOD+ connector Pin 4 SCK/RTS can be configured as a GPIO pin. Not sure which port is mapped to this pin as I will need to control this pin as a GPIO.Thanks.
Resolved! Cannot start HSE on G474RE nucleo board
I have a brand new Nucleo G474RE board. I see that the default HSE is X3 at 24MHz. The solder bridges and capacitors are OK as per the board documentation, and checked to be physically on the board.But I cannot get HSE to oscilate. The (autogenerated...
STM32L452 ADC Vref Voltage Difference Between Old and New Boards
We are working with a board featuring the STM32L452 microcontroller, configured for ADC readings. On my old board with the same MCU, the Vref (reference voltage for ADC) measures 3.3 V even without flashing any code, which is as expected. However, in...
