ucos II+ucGUI+s3c2410+LCD+觸摸屏整合

1) 設置中斷向量，開中斷：

void SetTSInterrupt(void)

{

rADCDLY = (50000);

rADCCON = (114)|(ADCPRS6)|(73)|(02)|(01)|(0);

rADCTSC = (08)|(17)|(16)|(05)|(14)|(03)|(02)|(3);

pISR_ADC = (U32)TSIrqISR; //

rINTMSK = ~(BIT_ADC);

rINTSUBMSK = ~(BIT_SUB_TC);

}

2) 中斷處理函數：

static void TSIrqISR(void)

{

int i;

U32 Pt[6];

rINTSUBMSK |= (BIT_SUB_ADC|BIT_SUB_TC);

if(rADCDAT0 0x8000)

{//抬起

isDown = 0;

rADCTSC = 0xff; // Set stylus down interrupt

TX = -1;

TY = -1; //抬起觸筆時，TX,TY要值成不大于0的數

}

else //按下

{ isDown = 1;

rADCTSC=(08)|(07)|(06)|(15)|(14)|(13)|(02)|(1);

for(i=0;i

for(i=0;i5;i++) //5 times

{

rADCCON|=0x1; // Start X-position conversion

while(rADCCON 0x1); // Check if Enable_start is low

while(!(0x8000rADCCON)); // Check ECFLG

Pt[i]=(0x3ffrADCDAT0);

}

Pt[5]=(Pt[0]+Pt[1]+Pt[2]+Pt[3]+Pt[4])/5;//多次采樣取平均值

TX = Pt[5];

rADCTSC=(08)|(07)|(16)|(15)|(04)|(13)|(02)|(2);

for(i=0;i

for(i=0;i5;i++) //5 times

{

rADCCON|=0x1; // Start Y-position conversion

while(rADCCON 0x1); // Check if Enable_start is low

while(!(0x8000rADCCON)); // Check ECFLG

Pt[i]=(0x3ffrADCDAT1);

}

Pt[5]=(Pt[0]+Pt[1]+Pt[2]+Pt[3]+Pt[4])/5;// 多次采樣取平均值

TY = Pt[5];

rADCTSC=(18)|(17)|(16)|(05)|(14)|(03)|(02)|(3);

}

//cprintf(%d,%dn,TX,TY);

OSMboxPost(TouchMbox, 0);//向處理觸摸進程發消息

rSUBSRCPND |= BIT_SUB_TC;

rINTSUBMSK = ~(BIT_SUB_TC); // Unmask sub interrupt (TC)

ClearPending(BIT_ADC);

}

3) 需要的量：

#define LOOP 1

#define ADCPRS 0x27

int TX=0;//觸摸坐標x

int TY=0;//觸摸坐標y

extern OS_EVENT *TouchMbox;

int isDown;

4) 觸摸屏校準：

Ucgui390中，帶有一校準程序(于TOUCH_Calibrate.c中)，可以改寫為我所用(見下文)。

也可設置默認值，測出左下最小坐標minX，minY和右上最大坐標maxX，maxY，注意是觸摸坐標，不是lcd坐標，如下填寫配置文件GUITouchConf.h:

#define GUI_TOUCH_AD_LEFT minX

#define GUI_TOUCH_AD_TOP maxY

#define GUI_TOUCH_AD_RIGHT maxX

#define GUI_TOUCH_AD_BOTTOM minY

#define GUI_TOUCH_SWAP_XY 0

#define GUI_TOUCH_MIRROR_X 1

#define GUI_TOUCH_MIRROR_Y 1

#define TOUCH_NEED_CALIBRATE 0

3、如下填寫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_SIZE 12500 /* Size of dynamic memory ... For WM and memory devices*/

#define GUI_WINSUPPORT 1 /* Window manager package available */

#define GUI_SUPPORT_MEMDEV 1 /* Memory devices available */

#define GUI_SUPPORT_AA 1 /* Anti aliasing available */

4、ucgui與lcd驅動函數的連接，即修改LCDWin.c文件：

在LCDWin.c中，去掉無用的頭文件包含。

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

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

即將“LCDSIM_XX”改成“LCD2410_XX”，這兩個函數位于lcd驅動文件中。

……………………………

#define SETPIXEL(x, y, c)

if (!_CheckBound(c)) {

LCD2410_SetPixel(x, y, c, LCD_DISPLAY_INDEX);

}

#else

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

#endif

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

……………………………

static void _XorPixel(int x, int y) {

unsigned int Index = LCD_L0_GetPixelIndex(x,y);

LCD2410_SetPixel(x, y, LCD_NUM_COLORS-1-Index, LCD_DISPLAY_INDEX);

}

……………………………

int LCD_L0_Init(void) {

return LCD2410_Init();//調用lcd初始化函數

}

5、某些編譯器(如：ads1.2)不會初始化全局變量，因此做如下事：

1) 修改如下函數為：(位于GUICore.c)

static void _InitContext(GUI_CONTEXT* pContext) {

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