用stm32f4，直接显示，用的是点子的代码
 DMA_InitStructure.DMA_Channel = DMA_Channel_1;  //?¨??1 DCMI?¨?? 
  DMA_InitStructure.DMA_PeripheralBaseAddr = (u32)&DCMI->DR; 
  DMA_InitStructure.DMA_Memory0BaseAddr = (uint32_t)lcd_ram;//LCD地址
  DMA_InitStructure.DMA_DIR = DMA_DIR_PeripheralToMemory;//???è???????÷????
  DMA_InitStructure.DMA_BufferSize = DMA_BufferSize;  //?????????? 
  DMA_InitStructure.DMA_PeripheralInc = DMA_PeripheralInc_Disable;//???è·?????????
  DMA_InitStructure.DMA_MemoryInc = DMA_MemoryInc_Disable;//?????÷????????
  DMA_InitStructure.DMA_PeripheralDataSize = DMA_PeripheralDataSize_Word;//???è?????¤??:32??
  DMA_InitStructure.DMA_MemoryDataSize = DMA_MemoryDataSize_HalfWord;//?????÷?????¤?? 
  DMA_InitStructure.DMA_Mode = DMA_Mode_Circular;// ???????·???? 
  DMA_InitStructure.DMA_Priority = DMA_Priority_High;//????????
  DMA_InitStructure.DMA_FIFOMode = DMA_FIFOMode_Enable; //FIFO????        
  DMA_InitStructure.DMA_FIFOThreshold = DMA_FIFOThreshold_Full;//??????FIFO 
  DMA_InitStructure.DMA_MemoryBurst = DMA_MemoryBurst_Single;//???è??·?????????
  DMA_InitStructure.DMA_PeripheralBurst = DMA_PeripheralBurst_Single;//?????÷??·?????????
  DMA_Init(DMA2_Stream1, &DMA_InitStructure);  //??????DMA Stream*/  
DMA_Init(DMA2_Stream1, &DMA_InitStructure); 

下面是DCMI设置
DCMI_InitStructure.DCMI_CaptureMode = DCMI_CaptureMode_Continuous;      //????????
DCMI_InitStructure.DCMI_CaptureRate = DCMI_CaptureRate_All_Frame;            //????????
DCMI_InitStructure.DCMI_ExtendedDataMode = DCMI_ExtendedDataMode_8b;       / /8??????????  
DCMI_InitStructure.DCMI_HSPolarity = DCMI_HSPolarity_Low;                   //HSYNC ?????????§
DCMI_InitStructure.DCMI_PCKPolarity = DCMI_PCKPolarity_Rising;              //PCLK ?????????§
DCMI_InitStructure.DCMI_SynchroMode = DCMI_SynchroMode_Hardware;           //????????HSYNC,VSYNC
DCMI_InitStructure.DCMI_VSPolarity = DCMI_VSPolarity_Low;                //VSYNC ?????????§
DCMI_Init(&DCMI_InitStructure);

直接给LCD地址显示，LCD显示的乱七八糟，不成图像。但是如果用数组来显示160x120的话，是可以出视频。
是不是这样直接给数据每次都多了几个数据，把LCD扫描弄乱了？还是设置不对？
