Migrating FATFS SD Card code (on FreeRTOS) from STM32F7 to STM32H7

As the title says, I am trying to migrate some code that once was running on an STM32F7 over to STM32H7 (nucleo boards). I have had all sorts of learning hurdles switching over to the H7 which most have been resolved. The issues in general were due t...

I work with the TIMER2 in INPUT CAPTURE mode, the interrupt is triggered on rising or falling edge. I want to get both trigger times on both fronts using the conditional statement "if" and the HAL library.

STM32F103 boot loader question

Occasionally I get a crash - I think when stack meets heap in certain circumstances but I'm still working on that and it's not the issue I'm asking about.The problem is that when the processor crashes I use the boot loader to reload another code buil...

in STM32F373 SDADC example for RTD measurement and I am getting huge noise in raw ADC and RTD temperature variation after configuring other peripherals like TSC and SPI for LCD.

I have used SDADC RTD temperature measurement example from \STM32Cube\Repository\STM32Cube_FW_F3_V1.10.0\Projects\STM32373C_EVAL\Examples\SDADC\SDADC_TempMeasurementwith the same micro STM32F373 and I am getting huge noise in raw ADC and RTD temperat...

how i can recover the state of HAL_Init () with stm32f4

HAL_StatusTypeDef HAL_Init( void ){ HAL_StatusTypeDef statue; /* Configure Instruction cache through ART accelerator */ #if (ART_ACCLERATOR_ENABLE != 0)  __HAL_FLASH_ART_ENABLE();#endif /* ART_ACCLERATOR_ENABLE */ /* Configure Flash prefetch */#if (P...

found a bug with cube_mx generate code in HAL_SPI_Transmit_DMA function.

In this function call the package mode check wrong buffer alignment,should check tx buffer not rx buffer.FYI.Typhoon

Communication UART

Good morning,HAL_UART_Transmit(&huart2,myRxData,11,10);HAL_UART_Receive(&huart2,myRxData,11,100);My question is: only to make a test of sending and receiving data is enough to use the previous functions and make the connection of the pins tx with rx ...
