STM32F407 - HSE Bypass using external clock.

HiI wish to use an external clock into PH0 from an oscillator module already present in my design.Does this mean PH1 becomes a spare pin?ThanksAndy.

STM32H745 and SPI + DMA

Hi to all,I need to send on every TIM interrupt a packet stream to SPI1. I can't use the HAL_SPI_Transmit(...) because it is blocking....so I need to use the DMA but not in circular mode.I can not use the synchronization of DMA with lptim using DMAMU...

Problems displaying color STemWin on ILI9488 After loading the firmware into the microcontroller STM32F405RG, only black and white colors are displayed. How to fix it?

How to import Stmcube Mcu package examples code in atollic true studio? I want to run I2C communication between two nucleo STM32103RBx Boards How can I import it or I have to do it with STMCubeMx?

I have Run blinky code USART code with STMCUBEMx and atollic studio now I want to implement I2C communication between Nucleo boards. I searched And download stmcube MCU Package for STM32F1 series I have put it in the same workspace (same worksp...

My target is :my device when the main run is OFF = SLEEPThen its right this code ?When i pressed for a time > 300 mses button (OFF/on ) my device must wakeup , my button il connected to pin wakeup this is my code Which timer and i must use for t...

Dear sir We had purchased product STM32F427IIT6 and STM32F427IIH6 , now we do reliability prediction work and need MTBF or FIT value. Please send them to us.

Program microcontroller in Python using ctypes to utilize HAL libraries

I am familiar with the STM32CubeIDE; I've done several of the examples and understand how it works on a basic level. What I need to do is create a user-interface (hence needing Python) that will allow a user to interact with the microcontroller. Ctyp...

Correct way to end DMA

Our STM32F7 no-OS system calls HAL_MMC_ReadBlocks_DMA() to read multiple blocks of data from eMMC storage.The STM HAL sets the MMC state machine SDMMC_DTIMER register at the start of the DMA.The DMA completes and our code receives the interrupt and h...
