[ucgui] 对话框6——触屏位置简单例子

>_<:直接调用函数获得触屏位置：

• xPhys = GUI_TOUCH_GetxPhys(); /* Get the A/D mesurement result in x */
• yPhys = GUI_TOUCH_GetyPhys(); /* Get the A/D mesurement result in y */

 1 void MainTask_touch(void) {

 2   GUI_Init();

 3   GUI_CURSOR_Show();

 4   GUI_CURSOR_Select(&GUI_CursorCrossL);

 5   GUI_SetBkColor(GUI_WHITE);

 6   GUI_SetColor(GUI_BLACK);

 7   GUI_Clear();

 8   GUI_DispString("Measurement of\nA/D converter values");

 9   while (1) {

10     GUI_PID_STATE TouchState;

11     int xPhys, yPhys;

12     GUI_TOUCH_GetState(&TouchState);  /* Get the touch position in pixel */

13     xPhys = GUI_TOUCH_GetxPhys();     /* Get the A/D mesurement result in x */

14     yPhys = GUI_TOUCH_GetyPhys();     /* Get the A/D mesurement result in y */

15     /* Display the measurement result */

16     GUI_SetColor(GUI_BLUE);

17     GUI_DispStringAt("Analog input:\n", 0, 20);

18     GUI_GotoY(GUI_GetDispPosY() + 2);

19     GUI_DispString("x:");

20     GUI_DispDec(xPhys, 4);

21     GUI_DispString(", y:");

22     GUI_DispDec(yPhys, 4);

23     /* Display the according position */

24     GUI_SetColor(GUI_RED);

25     GUI_GotoY(GUI_GetDispPosY() + 4);

26     GUI_DispString("\nPosition:\n");

27     GUI_GotoY(GUI_GetDispPosY() + 2);

28     GUI_DispString("x:");

29     GUI_DispDec(TouchState.x,4);

30     GUI_DispString(", y:");

31     GUI_DispDec(TouchState.y,4);

32     /* Wait a while */

33     GUI_Delay(100);

34   };

35 }
