STM32L1 SPI always busy after DMA TX/RX

I am using an STM32L151VET7 as a full-duplex SPI slave, and after using HAL_SPI_TransmitReceive_DMA and receiving/transmitting any number of bytes, the SPI remains busy, and further calls to HAL_SPI_TransmitReceive_DMA return HAL_BUSY. Upon transmiss...

ADC + DMA (One-Shot Mode - SW-based Trigger)

Hello,I would like to use ADC with a group of several channels (ScanMode = Enabled) along with the DMA. However, I would like to avoid to use the DMA in circular buffer mode. I have seen so far that most of the examples and external literatures are b...

Bug in BSP driver for STM32H743-EVAL onboard LEDs

In case anybody wondered why the red LED of STM32H743-EVAL does not work unless I/O extender is enabled - here is the fix.In this placehttps://github.com/STMicroelectronics/STM32CubeH7/blob/beced99ac090fece04d1e0eb6648b8075e156c6c/Drivers/BSP/STM32H7...

STM32L476RG. I write 70bytes to an SD card (8GB) using SDIO 4-bit mode every 5-seconds. After exactly 390 writes the program jumps to the HardFault loop. If I remove the SD card the program runs forever so the problem is definitely the SD loop.
