Use HAL_SPI_Receive_DMA receive data. Sometimes the received data shift 3 bytes. Why? The board is STM32F750, build as SPI slave.
SPI slave receives data of unknow size.When SPI master gives a rising edge, SPI slave detects the rising edge and starts HAL_SPI_Receive_DMA(define a large size amount of data to be received). When SPI master gives a falling edge, SPI slave detects t...
