stm32如何获取图片的像素？

libing64

以下是LCD显示所指向的地址，
#define FSMC_LCD_ADDRESS    0x64000002
当摄像头获取图片之后，通过DMA将数据传输至此处，

  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_100MHz;

  GPIO_InitStructure.GPIO_OType = GPIO_OType_PP;

  GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_UP ;  

  GPIO_Init(GPIOA, &GPIO_InitStructure);

  /* D5,DCMI_VSYNC(PB6/7) */

  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_6 | GPIO_Pin_7;

  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF;

  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_100MHz;

  GPIO_InitStructure.GPIO_OType = GPIO_OType_PP;

  GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_UP ;  

  GPIO_Init(GPIOB, &GPIO_InitStructure);

 

  /* D0..D4(PC6/7/8/9/11) */

  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_6 | GPIO_Pin_7 | GPIO_Pin_8 | 

                                GPIO_Pin_9 | GPIO_Pin_11;

  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF;

  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_100MHz;

  GPIO_InitStructure.GPIO_OType = GPIO_OType_PP;

  GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_UP ;  

  GPIO_Init(GPIOC, &GPIO_InitStructure);

  /* D6,D7(PE5/6) */

  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_5 | GPIO_Pin_6;

  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF;

  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_100MHz;

  GPIO_InitStructure.GPIO_OType = GPIO_OType_PP;

  GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_UP ;  

  GPIO_Init(GPIOE, &GPIO_InitStructure);

  

  /* DCMI configuration *******************************************************/ 

  DCMI_InitStructure.DCMI_CaptureMode = DCMI_CaptureMode_Continuous;

  DCMI_InitStructure.DCMI_SynchroMode = DCMI_SynchroMode_Hardware;

  DCMI_InitStructure.DCMI_PCKPolarity = DCMI_PCKPolarity_Rising;

  DCMI_InitStructure.DCMI_VSPolarity = DCMI_VSPolarity_High;

  DCMI_InitStructure.DCMI_HSPolarity = DCMI_HSPolarity_High;

  DCMI_InitStructure.DCMI_CaptureRate = DCMI_CaptureRate_All_Frame;

  DCMI_InitStructure.DCMI_ExtendedDataMode = DCMI_ExtendedDataMode_8b;

  

  DCMI_Init(&DCMI_InitStructure);

  /* Configures the DMA2 to transfer Data from DCMI to the LCD ****************/

  /* Enable DMA2 clock */

  RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_DMA2, ENABLE);  

  

  /* DMA2 Stream1 Configuration */  

  DMA_DeInit(DMA2_Stream1);

  DMA_InitStructure.DMA_Channel = DMA_Channel_1;  

  DMA_InitStructure.DMA_PeripheralBaseAddr = DCMI_DR_ADDRESS;

  

 

//此处是DMA的目的地址

  DMA_InitStructure.DMA_Memory0BaseAddr = FSMC_LCD_ADDRESS;

  

   

  DMA_InitStructure.DMA_DIR = DMA_DIR_PeripheralToMemory;

  DMA_InitStructure.DMA_BufferSize = 1;

  //与串口数据大小一样

  DMA_InitStructure.DMA_PeripheralInc = DMA_PeripheralInc_Disable; //外设地址增模式关闭

  DMA_InitStructure.DMA_MemoryInc = DMA_MemoryInc_Disable; //存储器地址增模式关闭

  DMA_InitStructure.DMA_PeripheralDataSize = DMA_PeripheralDataSize_Word; //摄像头数据寄存器大小为1个字

  DMA_InitStructure.DMA_MemoryDataSize = DMA_MemoryDataSize_HalfWord; //液晶显示屏数据大小为半个字

  DMA_InitStructure.DMA_Mode = DMA_Mode_Circular; //循环模式可传输连续的数据流

  DMA_InitStructure.DMA_Priority = DMA_Priority_High;

  DMA_InitStructure.DMA_FIFOMode = DMA_FIFOMode_Enable;         

  DMA_InitStructure.DMA_FIFOThreshold = DMA_FIFOThreshold_Full;

  DMA_InitStructure.DMA_MemoryBurst = DMA_MemoryBurst_Single;

  DMA_InitStructure.DMA_PeripheralBurst = DMA_PeripheralBurst_Single;

     

  DMA_Init(DMA2_Stream1, &DMA_InitStructure);

请问如何才能将存在给地址的图片的数据取出呢？
通过指针吗？该怎么写呢？

呵呵，我自己摸索成功了，晚上花了一整晚

还不睡觉?

嗯嗯，晚上整理 了一下资料到空间分享了。晚安啊原子大哥

原子哥，这个事stm32f207，做项目需要摄像头，但是207的资料非常少，所以只能过来问问你啊~
