DMA 的 Stream 和 channel 连接的外设是有规定的 手册里面有写 不能随便换 DMA_ITConfig(DMA2_Stream1,DMA_IT_TC,ENABLE);//传送完成中断 DMA_Init(DMA2_Stream1, &DMA_InitStructure); NVIC_InitStructure.NVIC_IRQChannel = DMA2_Stream1_IRQn; NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 1; NVIC_InitStructure.NVIC_IRQChannelSubPriority = 2; NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE; NVIC_Init(&NVIC_InitStructure); 另外我这边也是用的fsmc驱动tft 遇到了问题 就是图像数据 传不完整
