ucos II+ucGUI+s3c2410+LCD+触摸屏整合

OSMboxPend(TouchMbox, 0, err); /* Acquire semaphore to perform random numbers */

CONSOL_Printf(Got a message\n);

GUI_TOUCH_Exec();//

}

}

2) 如下修改函数 GUI_TOUCH_Exec()：

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

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 */

}
