I am using STM32L496 Nucelo, CubeMX 6.1.1; FATFS, DMA SDMMC with FreeRtos. For some reason I have problems when it comes to using DMA2 Channel 4 with FreeRtos. When it is selected for SDMMC1_TX then I can mount SD card and read data without any probl...
Hi there, I wonder when I transmit the wrong data package from peripheral to memory, as the wrong size as I configured, where the offset pointer locates that the location for the next transmission is not at the start of the memory (memory 0 since I ...
I need to implement a single channel software triggered ADC scan in an interrupt callback paced at 10ms intervals, since the rate cannot be controlled in DMA.I never had an issue doing this with CMSIS, yet, HAL seems to be, well, difficult is the nic...

Hi!I'm using STM32H7 for a new project, and I need to send data through HAL_SPI_Transmit_DMA to an external MRAM. I have a block of 34000 bytes. If i send this: HAL_SPI_Transmit_DMA(&MRAM_SPI_H, buf, 34000); there is some write problem (when I read t...
