基于STM32CubeMX开发F407移植UCGUI出现鼠标残影

3.5寸TFT320*480  驱动IC是ILI9488.    大家有没有CubeMX下移植UCGUI遇到这种想象
网上有说读点错误的有说FSMC配置问题的，都有试过。
u16 LCD_BGR2RGB(u16 c)
{
u16  r, g, b;
b = (c>>0)  & 0x1f;
g = (c>>5)  & 0x3f;
r = (c>>11) & 0x1f;
return( (b<<11) + (g<<5) + (r<<0) );
}

u16 LCD_GetPoint(u16 x,u16 y)
{
u16 color;
   if(x>=lcddev.width||y>=lcddev.height)return 0; //超过了范围,直接返回
   LCD_SetCursor(x,y);

   LCD_WR_REG(0X2E);//9486 发送读GRAM指令
color=LCD_RD_data(); //读出颜色值
opt_delay(2);
color=LCD_RD_data();          //实际坐标颜色
opt_delay(2);

//    return (LCD_BGR2RGB(color)); //模式1
   return color;    //模式2
}

读点两个模式都试过,使用模式2时红色背景下无拖影，使用模式1，红色背景下拖影变成蓝色，蓝色背景下拖影依然是黑色
LCDNull.c部分代码
/*********************************************************************

void LCD_L0_SetPixelIndex(int x, int y, int PixelIndex)

}

unsigned int LCD_L0_GetPixelIndex(int x, int y)
{
  return LCD_GetPoint(x,y);
}

/*********************************************************************

/* 反转像素函数 */
void LCD_L0_XorPixel(int x, int y)
{
LCD_PIXELINDEX Index = LCD_GetPoint(x,y);
   LCD_SetPoint(x,y,LCD_NUM_COLORS-1-Index);
}

/* 绘制水平线函数 */
void LCD_L0_DrawHLine(int x0,int y,int x1)
{
GUI_Line(x0,y,x1,y,LCD_COLORINDEX);
}

/* 绘制垂直线函数 */
void LCD_L0_DrawVLine(int x,int y0,int y1)
{
GUI_Line(x,y0,x,y1,LCD_COLORINDEX);
}

/* 填充矩阵函数 */
void LCD_L0_FillRect(int x0, int y0, int x1, int y1)
{
#if !LCD_SWAP_XY
//  for (; y0 <= y1; y0++) {
// LCD_L0_DrawHLine(x0,y0, x1);
//  }
   LCD_Fill(x0,y0,x1,y1,LCD_COLORINDEX);
#else
  for (; x0 <= x1; x0++) {
LCD_L0_DrawVLine(x0,y0, y1);
  }
#endif
}

主函数部分代码
  ILI9488_Init();
TP_Init();

GUI_Init();
GUI_CURSOR_Show(); //显示鼠标,测试触摸屏必须打开窗口功能 GUI_WINSUPPORT

  hWin=WM_CreateWindow(0,0,320,480,WM_CF_SHOW,cbCallback,0);

// BUTTON_SetFont(hButton,&GUI_Font24_ASCII);
// BUTTON_SetText(hButton,"ON");

// BUTTON_SetTextColor(hButton,0,GUI_WHITE);  //弹起
// BUTTON_SetBkColor(hButton,0,GUI_BLUE);
// BUTTON_SetTextColor(hButton,1,GUI_BLACK);  //按下
// BUTTON_SetBkColor(hButton,1,GUI_RED);

GUI_SetBkColor(GUI_BLUE);
GUI_Clear();
GUI_Exec();
GUI_SetFont(&GUI_Font24_ASCII);
GUI_SetColor(GUI_RED);
GUI_DispStringAt("AAAAAAAAAAAAAA",40,150);

用的是卖家的LCD驱动，发现底层读出的与写入的颜色值不一致，显示的颜色是对的，我按RGB565一位一位递增写入（colorW），读出的colorR 天差地别
