STM32H563ZI can read/write SD Card, but USB MSC is not recognized by PC

I am currently developing a USB Mass Storage application using the STM32H563ZI with the following architecture:PC ← USB ← NUCLEO-H563ZI ← SD CardThe SD Card and USB Device have both been tested separately, and each works correctly on its own.However,

CubeMX does not generate all required driver files for LPTIM with LL

LL_LPTIM_Disable calls LL_RCC_GetSystemClocksFreq, but CubeMX does not generate stm32u5xx_ll_rcc.cThis causes a linker error due to undefined reference.A minimal reproduction .ioc file is attached.

Is ADC driver (op-amp based) is needed for measuring over cable with STM32 ADC?

Hello ST team,I am designing a hardware with STM32G4 family. I want to measure a differential signal by MCU's ADCs over a cable of 50 cm. Is it needed to use op-amp as ADC driver or I can connect it to the MCU pins directly?

ST memory board configured for dual qspi on two octospi on STM32H5E5 Nucleo

Hello,I just purchased two STM32H5E5 Nucleo boards along with two of the ST Memory board kits. What I am planning is to take one of the QSPI flash M.2 boards and reconfigure it so that the memory(s) attached to OCTOSPI1 are two identical flash chips,

STM32C5 - PB6 - electrical short with VDD

Hi, I am currently evaluating STM32C532KBU6, where I noticed the PB6 gets shorted (~20 ohms) with VDD of the MCU, as soon as the MCU is powered. When not powered, I am measuring ~4 Mega ohms between PB6 and VDD. I have not set any Option Bytes and di
