SPI + DMA receive only on STM32F4
Posted on September 13, 2017 at 16:56In my situation, I need to do SPI receiving with DMA (master side), and not care about Tx. I have three choices in the STM32Cube: Full-duplex masterHalf-duplex masterReceive only masterAnd I have two choices for...
Filter SPI Rx DMA complete event in HAL_SPI_TxRxCpltCallback()
Posted on September 13, 2017 at 16:05I'm using SPI with DMA for both Tx and Rx. So I call the relevant HAL API : 'HAL_SPI_TransmitReceive_DMA()'. And I only want to response to the Rx complete event. I find two possible places to filter the event: ...
