处理方式：SYNC模式，DE通过10K拉高（不连接BF532任何IO），起作用的HS,VS2个信号，时序已经和说明书上匹配，就它娘的没反应，现象为白屏白屏，就是显示不出图像，调试看到SDRAM内存数据，图像正确。

知道的朋友给个参考啊。。。

这是初始化程序：

其中：HS_PNT=800，VS_PNT=480

hs_pnt_blank=1056,vs_pnt_blank=525

时钟为33.3MHZ.

void InitDMA(void)
{  
*pDMA0_START_ADDR = &DisplayBuffer[0][0];

*pDMA0_X_COUNT = hs_pnt;
*pDMA0_X_MODIFY = 2;
*pDMA0_Y_COUNT = vs_pnt_blank;
*pDMA0_Y_MODIFY = 2;
*pDMA0_CONFIG = 0x1034;
}

void InitPPI(void)
{
*pPPI_CONTROL = 0x781e;
*pPPI_DELAY = 46;
*pPPI_COUNT = hs_pnt-1;
*pPPI_FRAME = vs_pnt_blank;
}

void InitTimer(void)
{
*pTIMER1_PERIOD  = hs_pnt_blank;
*pTIMER1_WIDTH  = 35;
*pTIMER1_CONFIG  = 0x00a9;
*pTIMER2_PERIOD  = hs_pnt_blank*vs_pnt_blank;
*pTIMER2_WIDTH  = hs_pnt_blank*10;
*pTIMER2_CONFIG  = 0x00a9;
}

void PPI_TMR_DMA_Enable(void)
{
*pDMA0_CONFIG |= 0x1;
asm("ssync;");
InitTimer();  
*pPPI_CONTROL |= 0x1;  
asm("ssync;");
*pTIMER_ENABLE|= 0x0006;
asm("ssync;");
}

void PPI_TMR_DMAR_Disable(void)
{
*pDMA0_CONFIG &= (~0x1);
*pPPI_CONTROL &= (~0x1);
}

它娘的，终于搞定了，这狗日的供应商，给我的是一个坏屏幕。。。。

贴出源程序，SCLK为100MHZ,TFT‘DCLK为33.3MHZ...
