1.编写驱动，主要为Lcd驱动和触摸屏驱动：

lcd驱动实现画点函数LCD2410_SetPixel(x,y,c)。对dm2410实验板上的lcd，左上为原点（0，0）

触摸屏驱动计算出触摸屏的坐标（x，y），对dm2410实验板上的触摸屏，左下为原点，但不一定是（0，0）

2.触摸屏校准：

测出左下最小坐标minX，minY和右上最大坐标maxX，maxY

如下填写GUITouchConf.h:

#define GUI_TOUCH_AD_LEFTminX

#define GUI_TOUCH_AD_TOPmaxY

#define GUI_TOUCH_AD_RIGHTmaxX

#define GUI_TOUCH_AD_BOTTOM minY

#define GUI_TOUCH_SWAP_XY0

#define GUI_TOUCH_MIRROR_X1

#define GUI_TOUCH_MIRROR_Y1

3.如下填写GUIConf.h：

#define GUI_OS(1)/* Compile with multitasking support */

#define GUI_SUPPORT_TOUCH(1)/* Support a touch screen (req. win-manager) */

#define GUI_SUPPORT_UNICODE(1)/* Support mixed ASCII/UNICODE strings */

#define GUI_SUPPORT_CHINESE(1)

#define GUI_DEFAULT_FONT&GUI_Font6x8

#define GUI_ALLOC_SIZE22500/* Size of dynamic memory ... For WM and memory devices*/

#define GUI_WINSUPPORT1/* Window manager package available */

#define GUI_SUPPORT_MEMDEV1/* Memory devices available */

#define GUI_SUPPORT_AA1

4.如下填写LCDConf.h:

#define LCD_XSIZE(800)/* X-resolution of LCD, Logical coor. */

#define LCD_YSIZE(480)/* Y-resolution of LCD, Logical coor. */

#define LCD_BITSPERPIXEL (16)

#define LCD_CONTROLLER1

#define LCD_SWAP_RB_0 1

5.ucgui与lcd驱动函数的连接：

在LCDWin.c中，去掉无用的头文件包含。

#define SETPIXEL(x, y, c) LCD2410_SetPixel(x, y, c)

#define GETPIXEL(x, y)LCD2410_GetPixel(x,y)

即将“LCDSIM_XX”改成“LCD2410_XX”，这两个函数位于lcd驱动文件中。

6.某些编译器不会初始化全局变量，因此做如下事：

1)修改如下函数为：（位于GUICore.c）

static void _InitContext(GUI_CONTEXT* pContext) {

memset(pContext,0,sizeof(GUI_CONTEXT))；//add

#if GUI_SUPPORT_MEMDEV

GUI_SelectLCD();

#else

LCD_SetClipRectMax();//LCD_L0_GetRect

#endif

pContext->pLCD_HL= &LCD_HL_APIList;

pContext->pAFont= GUI_DEFAULT_FONT;

pContext->pClipRect_HL = &GUI_Context.ClipRect;

pContext->PenSize= 1;

pContext->DrawMode = GUI_DRAWMODE_NORMAL;//add

pContext->TextMode = GUI_TEXTMODE_NORMAL;//add

pContext->TextAlign = GUI_TA_LEFT|GUI_TA_TOP;//add

pContext->AA_HiResEnable = 0;//add

/* Variables in WM module */

#if GUI_WINSUPPORT

pContext->hAWin= WM_GetDesktopWindow();

#endif

/* Variables in GUI_AA module */

pContext->AA_Factor = 3;

LCD_SetBkColor(GUI_DEFAULT_BKCOLOR);

LCD_SetColor(GUI_DEFAULT_COLOR);

}

2)自己编写如下函数：

void MyInit()

{

IsInitialized = 0;//MemDev

_IsInited = 0;//Win

WM__CreateFlags = 0;

GUI_CURSOR_pfTempHide = NULL;

GUI_Context.hDevData = 0;

WM__hCapture=0;

WM__hWinFocus=0;

WM_pfPollPID = 0;

WM_pfHandlePID = 0;

GUI_pfTimerExec = 0;

_KeyMsgCnt = 0;

}

该函数应在GUI_Init()调用之前调用。

7.由于没有加入ucos操作系统，自己编写如下函数模拟延时：

int ost = 0;

void My_X_Delay(int p)

{

int i = 0;

int j=0;

for(i=0; i

for(j=0; j

ost += p;

}

void MyDly(int Period)

{

int EndTime;

int tRem; /* remaining Time */

ost = 0;

EndTime = ost + Period;

while (tRem = EndTime - ost, tRem>0) {

GUI_Exec();

My_X_Delay((tRem >100) ? 100 : tRem);

}

}

因此将示例中的GUI_Delay(x)该为MyDly(x).

8.修改如下函数，接入lcd的初始化：(位于LCD.c)

intLCD_Init(void) {

int r;

GUI_DEBUG_LOG("\nLCD_Init...");

LCD_SetClipRectMax();

if ((r = LCD2410_Init()) != 0) //LCD2410_Init(),设置lcd寄存器

return r;

#if LCD_NUM_DISPLAYS > 1

if ((r = LCD_L0_1_Init()) != 0)

return r;

#endif

LCD_InitLUT();

/* Clear video memory */

LCD_SetDrawMode(GUI_DRAWMODE_REV);

LCD_FillRect(0,0, GUI_XMAX, GUI_YMAX);

LCD_SetDrawMode(0);

/* Switch LCD on */

LCD_On();

return 0;

}

9.如下修改GUI_X.c：

int GUI_X_GetTime(void)

{

return 0;

// return OSTimeGet();

}

void GUI_X_Delay(int ms)

{

// OSTimeDly(ms);

int i=0;

for(i=0; i

;

}

void GUI_X_ExecIdle(void) {

GUI_X_Delay(1);

}

void GUI_X_Unlock(void)

{

// OSSemPost(DispSem);

}

void GUI_X_Lock(void)

{

// U8 err;

// OSSemPend(DispSem, 0, &err);

}

U32 GUI_X_GetTaskId(void)

{

// if(bGUIInitialized){

//return ((INT32U)(OSTCBCur->OSTCBPrio)); /* < 64(è???ó??è??) */

// }

// else{

return 100; /* ??òa±￡?¤>64?′?é */

// }

}

void GUI_X_InitOS(void)

{

// DispSem = OSSemCreate(1);

}

void GUI_X_ErrorOut(const char *s){}

void GUI_X_Warn(const char *s){}

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

*

*GUI_X_Init()

*

* Note:

*GUI_X_Init() is called from GUI_Init is a possibility to init

*some hardware which needs to be up and running before the GUI.

*If not required, leave this routine blank.

*/

void GUI_X_Init(void) {

SetTsInterrupt(); //此处接入触摸屏的中断设置

GUI_TOUCH_SetDefaultCalibration();//关键函数

}

intGUI_TOUCH_X_MeasureX(void) {

return TX;

}

intGUI_TOUCH_X_MeasureY(void){

return TY;

}

void GUI_TOUCH_X_ActivateX(void) {}

void GUI_TOUCH_X_ActivateY(void) {}

void GUI_X_Log(const char *s){}

10.为了响应触摸屏，做如下事：

1)在触摸屏中断中，获得触摸坐标后，应调用如下函数：

GUI_TOUCH_Exec();

2)如下修改函数 GUI_TOUCH_Exec()，注释掉错误部分：

void GUI_TOUCH_Exec(void) {

#ifndef WIN32

static U8 ReadState;

int x,y;

/* calculate Min / Max values */

if (xyMinMax[GUI_COORD_X].Min < xyMinMax[GUI_COORD_X].Max) {

xMin = xyMinMax[GUI_COORD_X].Min;

xMax = xyMinMax[GUI_COORD_X].Max;

} else {

xMax = xyMinMax[GUI_COORD_X].Min;

xMin = xyMinMax[GUI_COORD_X].Max;

}

if (xyMinMax[GUI_COORD_Y].Min < xyMinMax[GUI_COORD_Y].Max) {

yMin = xyMinMax[GUI_COORD_Y].Min;

yMax = xyMinMax[GUI_COORD_Y].Max;

} else {

yMax = xyMinMax[GUI_COORD_Y].Min;

yMin = xyMinMax[GUI_COORD_Y].Max;

}

/* Execute the state machine which reads the touch */

//switch (ReadState) {

//case 0:

yPhys = TOUCH_X_MeasureY();

// TOUCH_X_ActivateY();/* Prepare X- measurement */

//ReadState++;

//break;

//default:

xPhys = TOUCH_X_MeasureX();

//TOUCH_X_ActivateX();/* Prepare Y- measurement */

/* Convert values into logical values */

#if !GUI_TOUCH_SWAP_XY/* Is X/Y swapped ? */

x = xPhys;

y = yPhys;

#else

x = yPhys;

y = xPhys;

#endif

if ((x xMax)| (y yMax)) {

GUI_TOUCH_StoreUnstable(-1,-1);

} else {

x = AD2X(x);

y = AD2Y(y);

GUI_TOUCH_StoreUnstable(x,y);

}

/* Reset state machine */

//ReadState=0;

// break;

//}

#endif /* WIN32 */

}

画点效率有待改进...........................
