可是dma.h文件里有
#define __HAL_DMA_CLEAR_FLAG(__HANDLE__, __FLAG__) \
(((uint32_t)((__HANDLE__)->Instance) > (uint32_t)DMA2_Stream3)? (DMA2->HIFCR = (__FLAG__)) :\
((uint32_t)((__HANDLE__)->Instance) > (uint32_t)DMA1_Stream7)? (DMA2->LIFCR = (__FLAG__)) :\
((uint32_t)((__HANDLE__)->Instance) > (uint32_t)DMA1_Stream3)? (DMA1->HIFCR = (__FLAG__)) : (DMA1->LIFCR = (__FLAG__)))

#define __HAL_DMA_ENABLE_IT(__HANDLE__, __INTERRUPT__)   (((__INTERRUPT__) != DMA_IT_FE)? \
((__HANDLE__)->Instance->CR |= (__INTERRUPT__)) : ((__HANDLE__)->Instance->FCR |= (__INTERRUPT__)))


这两个define都定义了啊 这是为什么呢困扰一天了

李志猛

#define __HAL_DMA_ENABLE_IT(__HANDLE__, __INTERRUPT__)   (((__INTERRUPT__) != DMA_IT_FE)? \
((__HANDLE__)->Instance->CR |= (__INTERRUPT__)) : ((__HANDLE__)->Instance->FCR |= (__INTERRUPT__))) 原因找到了 是这个define后面的语句有问题 但不知道怎么改了，毕竟这是官方库

正点原子

帮顶，用寄存器表示没这么多烦恼
