在初始化LTDC完成后，通过向显存地址写数据可以正常刷新界面颜色，但是调用GUIx之后，就花屏了，请老师们指点一下，谢谢，部分代码如下：
void MX_LTDC_Init(void)
{
LTDC_LayerCfgTypeDef pLayerCfg = {0};
LTDC_LayerCfgTypeDef pLayerCfg1 = {0};
hltdc.Instance = LTDC;
hltdc.Init.HSPolarity = LTDC_HSPOLARITY_AL;

hltdc.Init.PCPolarity = LTDC_PCPOLARITY_IPC;
hltdc.Init.HorizontalSync = 3;
hltdc.Init.VerticalSync = 0;
hltdc.Init.AccumulatedHBP = 161;
hltdc.Init.AccumulatedVBP = 17;
hltdc.Init.AccumulatedActiveW = 1185;
hltdc.Init.AccumulatedActiveH = 617;
hltdc.Init.TotalWidth = 1343;
hltdc.Init.TotalHeigh = 634;
hltdc.Init.Backcolor.Blue = 0;
hltdc.Init.Backcolor.Green = 255;
hltdc.Init.Backcolor.Red = 255;
if (HAL_LTDC_Init(&hltdc) != HAL_OK)
{
Error_Handler();
}
pLayerCfg.WindowX0 = 0;
pLayerCfg.WindowX1 = 1024;
pLayerCfg.WindowY0 = 0;
pLayerCfg.WindowY1 = 600;
pLayerCfg.PixelFormat = LTDC_PIXEL_FORMAT_RGB565;
pLayerCfg.Alpha = 255;
pLayerCfg.Alpha0 = 255;
pLayerCfg.BlendingFactor1 = LTDC_BLENDING_FACTOR1_CA;
pLayerCfg.BlendingFactor2 = LTDC_BLENDING_FACTOR2_CA;
pLayerCfg.FBStartAdress = 0xD0000000;
pLayerCfg.ImageWidth = 1024;
pLayerCfg.ImageHeight = 600;
pLayerCfg.Backcolor.Blue = 0;
pLayerCfg.Backcolor.Green = 255;
pLayerCfg.Backcolor.Red = 0;

{

}

{
Error_Handler();
}
}
