STEnWin移植问题，Alpha显示错误，LCD驱动没有问题。

ishark

在移植完成后显示错误，使用GUIDEMO演示也有错误。
LCD的写点与读点程序正常。

字符显示测试代码

[mw_shl_code=c,true]GUI_SetFont(&GUI_Font8x16); GUI_SetBkColor(GUI_BLUE); GUI_Clear(); GUI_SetPenSize(10); GUI_SetColor(GUI_RED); GUI_DrawLine(80, 10, 240, 90); GUI_DrawLine(80, 90, 240, 10); GUI_SetBkColor(GUI_BLACK); GUI_SetColor(GUI_WHITE); GUI_SetTextMode(GUI_TM_NORMAL); GUI_DispStringHCenterAt("GUI_TM_NORMAL" , 160, 10); GUI_SetTextMode(GUI_TM_REV); GUI_DispStringHCenterAt("GUI_TM_REV" , 160, 26); GUI_SetTextMode(GUI_TM_TRANS); GUI_DispStringHCenterAt("GUI_TM_TRANS" , 160, 42); GUI_SetTextMode(GUI_TM_XOR); GUI_DispStringHCenterAt("GUI_TM_XOR" , 160, 58); GUI_SetTextMode(GUI_TM_TRANS | GUI_TM_REV); GUI_DispStringHCenterAt("GUI_TM_TRANS | GUI_TM_REV", 160, 74);[/mw_shl_code]

正常显示应该是这个

我的程序显示

Alpha测试代码

[mw_shl_code=c,true]GUI_EnableAlpha(1); GUI_SetBkColor(GUI_WHITE); GUI_Clear(); GUI_SetColor(GUI_BLACK); GUI_DispStringHCenterAt("Alphablending", 45, 41); GUI_SetColor((0x40uL << 24) | GUI_RED); GUI_FillRect(0, 0, 49, 49); GUI_SetColor((0x80uL << 24) | GUI_GREEN); GUI_FillRect(20, 20, 69, 69); GUI_SetColor((0xC0uL << 24) | GUI_BLUE); GUI_FillRect(40, 40, 89, 89);[/mw_shl_code]

多边形测试代码

[mw_shl_code=c,true]const GUI_POINT aPoints[] = { { 40, 20}, { 0, 20}, { 20, 0} }; GUI_POINT aEnlargedPoints[GUI_COUNTOF(aPoints)]; void Sample(void) { int i; GUI_Clear(); GUI_SetDrawMode(GUI_DM_XOR); GUI_FillPolygon(aPoints, GUI_COUNTOF(aPoints), 140, 110); for (i = 1; i < 10; i++) { GUI_EnlargePolygon(aEnlargedPoints, aPoints, GUI_COUNTOF(aPoints), i * 5); GUI_FillPolygon(aEnlargedPoints, GUI_COUNTOF(aPoints), 140, 110); } }[/mw_shl_code]

问题已经解决。在移植的时候，这个函数void LCD_X_Config(void)的LCD驱动选择出现问题。

不要用排线，直接接到开发板上试一下

回复【3楼】ishark:
---------------------------------
你好， 我也遇到这个问题。我的驱动选择应该是对的啊。下面是的LCD_X_Config函数
  GUI_DEVICE * pDevice;
  CONFIG_FLEXCOLOR Config = {0};
  GUI_PORT_API ortAPI = {0};
  //
  // Set display driver and color conversion
  //
  pDevice = GUI_DEVICE_CreateAndLink(GUIDRV_FLEXCOLOR, GUICC_565, 0, 0);
  //
  // Display driver configuration, required for Lin-driver
  //
  LCD_SetSizeEx (0, XSIZE_PHYS , YSIZE_PHYS);
  LCD_SetVSizeEx(0, VXSIZE_PHYS, VYSIZE_PHYS);
  //
  // Orientation
  Config.Orientation =  GUI_SWAP_XY | GUI_MIRROR_Y;
  GUIDRV_FlexColor_Config(pDevice, &Config);
  //
  // Set controller and operation mode
  //
  ortAPI.pfWrite16_A0  = LcdWriteReg;
  ortAPI.pfWrite16_A1  = LcdWriteData;
  ortAPI.pfWriteM16_A1 = LcdWriteDataMultiple;
  ortAPI.pfReadM16_A1  = LcdReadDataMultiple;
  GUIDRV_FlexColor_SetFunc(pDevice, &PortAPI, GUIDRV_FLEXCOLOR_F66709, GUIDRV_FLEXCOLOR_M16C0B16);

楼主我的是白屏啊，你是怎么解决的
关于程序：
//配置程序,用于创建显示驱动器件,设置颜色转换程序和显示尺寸
void LCD_X_Config(void) {
GUI_DEVICE_CreateAndLink(&GUIDRV_Template_API, GUICC_M565, 0, 0); //创建显示驱动器件
LCD_SetSizeEx    (0, lcddev.width, lcddev.height);
LCD_SetVSizeEx   (0, lcddev.width, lcddev.height);
if(lcddev.id == 0X5510) //0X5510为4.3寸 800x480的屏
{
if(lcddev.dir == 0) //竖屏  // 2001:3520 6352
{     // 9147:3832 6288
GUI_TOUCH_Calibrate(GUI_COORD_X,0,480,0,479);
GUI_TOUCH_Calibrate(GUI_COORD_Y,0,800,0,799);
}else //横屏
{
//GUI_TOUCH_SetOrientation(GUI_SWAP_XY|GUI_MIRROR_Y); 
GUI_TOUCH_Calibrate(GUI_COORD_X,0,480,0,479); 
GUI_TOUCH_Calibrate(GUI_COORD_Y,0,800,0,799);
}
}else if(lcddev.id == 0X1963)//1963为7寸屏 800*480 
{
if(lcddev.dir == 0) //竖屏
{ // 6368 3816
//GUI_TOUCH_SetOrientation(GUI_SWAP_XY|GUI_MIRROR_Y);

}else //横屏
{
GUI_TOUCH_Calibrate(GUI_COORD_X,0,800,0,799); 
GUI_TOUCH_Calibrate(GUI_COORD_Y,0,480,0,479);
}
}else if(lcddev.id == 0X5310 || lcddev.id == 0X6804) //0X5510 0X6804为3.5寸 320x480
{
if(lcddev.dir == 0) //竖屏 
{
GUI_TOUCH_Calibrate(GUI_COORD_X,0,320,3931,226);

GUI_TOUCH_Calibrate(GUI_COORD_X,0,320,3931,226);
GUI_TOUCH_Calibrate(GUI_COORD_Y,0,480,3812,196); 
}
}
else             //其他屏幕全部默认为2.8寸 320X240
{
if(lcddev.dir == 0) //竖屏
{
GUI_TOUCH_Calibrate(GUI_COORD_X,0,lcddev.width,155,3903);
GUI_TOUCH_Calibrate(GUI_COORD_Y,0,lcddev.height,188,3935);
}else //横屏
{
GUI_TOUCH_SetOrientation(GUI_SWAP_XY|GUI_MIRROR_Y); 
GUI_TOUCH_Calibrate(GUI_COORD_X,0,240,155,3903); 
GUI_TOUCH_Calibrate(GUI_COORD_Y,0,320,188,3935);
}
}
}


那需要改哪里？我觉得原子哥这个程序已经很好了。我想问的是我的居然白屏，你具体是怎么解决的？？
