Hal spi transmit receive

WebOct 7, 2024 · To receive data via SPI in polling mode, HAL library has the following definition: HAL_SPI_Receive(SPI_HandleTypeDef *hspi, uint8_t *pData, uint16_t Size, uint32_t Timeout). I understand the first parameter. But, I'm confused about the second and third parameter. I've told CubeMx that the data size for SPI1 is 16 bits. WebApr 8, 2024 · though rxb that is in HAL_SPI_Receive_DMA(&hspi1, rxb, 3); is filled with 0. I've looked into SPI1.DR register, but it is 0, so I don't know what to think. I've tried to DMAStop on message TX and RX callbacks, also I've tried SPI_Abort. I've mixed priority levels in different ways: all equal. EXTI > SPI > DMARX > DMATX (and TX > RX)
