STM32F030C8T6 CUBEMX Hal库 SPI1 DMA发送完成标志怎么获取
MCU：STM32F030C8T6。MXcube 版本号：如图片所示。
请问 有SPI DMA发送完成中断吗？或者怎么通过查询方式获取SPI DMA发送完成标志？
用dma空闲中断 //以下是 stm32f0xx_hal_dma.h 的函数声明
HAL_StatusTypeDef HAL_DMA_Init(DMA_HandleTypeDef *hdma);
HAL_StatusTypeDef HAL_DMA_DeInit (DMA_HandleTypeDef *hdma);
/* Input and Output operation functions *****************************************************/
HAL_StatusTypeDef HAL_DMA_Start (DMA_HandleTypeDef *hdma, uint32_t SrcAddress, uint32_t DstAddress, uint32_t DataLength);
HAL_StatusTypeDef HAL_DMA_Start_IT(DMA_HandleTypeDef *hdma, uint32_t SrcAddress, uint32_t DstAddress, uint32_t DataLength);
HAL_StatusTypeDef HAL_DMA_Abort(DMA_HandleTypeDef *hdma);
HAL_StatusTypeDef HAL_DMA_Abort_IT(DMA_HandleTypeDef *hdma);
HAL_StatusTypeDef HAL_DMA_PollForTransfer(DMA_HandleTypeDef *hdma, uint32_t CompleteLevel, uint32_t Timeout);
void HAL_DMA_IRQHandler(DMA_HandleTypeDef *hdma);
HAL_StatusTypeDef HAL_DMA_RegisterCallback(DMA_HandleTypeDef *hdma, HAL_DMA_CallbackIDTypeDef CallbackID, void (* pCallback)( DMA_HandleTypeDef * _hdma));
HAL_StatusTypeDef HAL_DMA_UnRegisterCallback(DMA_HandleTypeDef *hdma, HAL_DMA_CallbackIDTypeDef CallbackID);

找不到DMA空闲中断服务函数呢 这个是 stm32f0xx_hal_spi.h 的函数声明

HAL_StatusTypeDef HAL_SPI_TransmitReceive(SPI_HandleTypeDef *hspi, uint8_t *pTxData, uint8_t *pRxData, uint16_t Size,

看不出哪个是与DMA空闲中断有关的::L 之前用标准库函数是有DMA空闲中断的，stm32cubeMX 生成的Hal库 找不到了？ oasisdong 发表于 2019-3-26 08:21
