DCMI接口DMA传送数据中断进不去

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

楼主可否贴上源码

你看下这个配置，这是DCMI驱动ov7670的配置

应该是设置DMA传输有误。

DCMI接口接收到数据后通知DMA需要DCMI_CaptureCmd(ENABLE)来设置 CR寄存器的CAPTURE位。看看是不是程序跑飞了？推荐贴上代码

的DMA传送是循环模式的，不会产生传输完成中断，但你可以设置帧中断

RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_DMA2, ENABLE);
//DMA2 Stream1 配置
DMA_DeInit(DMA2_Stream1);
DMA_InitStructure.DMA_Channel = DMA_Channel_1;
DMA_Init(DMA2_Stream1, &DMA_InitStructure);
我想问下，STM32的DCMI接口进行DMA传输非得这样配置吗？可不可以用DMA1或者另外的通道？我用另外的通道一直行不通

你的DMA中断没有设置
  NVIC_PriorityGroupConfig(NVIC_PriorityGroup_1);
  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);
在DMA初始化完成之后把这几句加上，相应的部分要修改。你在试试
