STM32 MCUs Embedded software

I tried to access sd-card from model by enabling freertos in stm32h7b3i but i get fopen error. It worked in stm32f746g-dk which has dma access in sdmmc. where in case of stm32h7b3I it has internal dma but there is no sign of dma link code with sdmmc1

STM32 F1 USBX usage problems

I first refer to the x-cube-azrtos-h7 example on STM32 H7 to migrate ThreadX and USBX. CDC HID, including the combination of the two, have been tested, and they all work normally.Then I ported ThreadX and USBX on STM32 F105RBT6. Currently, they can e...

Affected driver library: STM32Cube_FW_U5 v1.0.0 and patch v1.0.2File: stm32u5xx_ll_spi.hFunction affected: LL_SPI_ReceiveData16Bug: Current implementation performs a 32bit access to RXDR register and then casts the result to 16 bits. This leads to un...

LL_ADC_ConfigOverSamplingRatioShift is not using correct ratio mask for ADC3 on STM32H73x CubeMX v6.3.0

Currently there is only:__STATIC_INLINE void LL_ADC_ConfigOverSamplingRatioShift(ADC_TypeDef *ADCx, uint32_t Ratio, uint32_t Shift){  MODIFY_REG(ADCx->CFGR2, (ADC_CFGR2_OVSS | ADC_CFGR2_OVSR), (Shift | (((Ratio - 1UL) << ADC_CFGR2_OVSR_Pos))));}which...

I'm using X-CUBE-USB-AUDIO package with different eval board, I am not able to record any voice. Is there any utility that needs to be use to make this package work? Please help me.

Does the USB as a mass storage device enter a sleep state? if so, how do i prevent this?

The ADCs I'm logging data from occasionally shut off and then come back on and start streaming data. When this happens, the USB seems to have entered a sleep state as the write time for the packet header goes from taking ~20 milliseconds to taking up...
