STemwin触摸屏移植一直没反应

我对照原子的PDF教程移植EMwin，移植到触摸屏的时候没有认可反应
程序：

void Mytouch_MainTask(void)
{
int i;
GUI_PID_STATE TouchState;
int xPhys;
int yPhys;
GUI_Init();
WM_SetCreateFlags(WM_CF_MEMDEV);
GUI_SetFont(&GUI_Font20_ASCII);
GUI_CURSOR_Show();
GUI_CURSOR_Select(&GUI_CursorCrossL);
GUI_SetBkColor(GUI_WHITE);
GUI_SetColor(GUI_BLACK);
GUI_Clear();
GUI_DispString("Measurement of\nA/D converter values");
while (1)
{
GUI_TOUCH_GetState(&TouchState); // Get the touch position in pixel
// printf("TouchState.Layer=%d TouchState.Pressed=%d  ",TouchState.Layer,TouchState.Pressed,TouchState.x);
// printf("TouchState.x=%d  ");

xPhys = GUI_TOUCH_GetxPhys(); // Get the A/D mesurement result in x
yPhys = GUI_TOUCH_GetyPhys(); // Get the A/D mesurement result in y
// printf("%d  %d  ",xPhys,yPhys);
GUI_SetColor(GUI_BLUE);
GUI_DispStringAt("Analog input:\n", 0, 40);
GUI_GotoY(GUI_GetDispPosY() + 2);
GUI_DispString("x:");
GUI_DispDec(xPhys, 4);
GUI_DispString(", y:");
GUI_DispDec(yPhys, 4);
GUI_SetColor(GUI_RED);
GUI_GotoY(GUI_GetDispPosY() + 4);
GUI_DispString("\nPosition:\n");
GUI_GotoY(GUI_GetDispPosY() + 2);
GUI_DispString("x:");
GUI_DispDec(TouchState.x,4);
GUI_DispString(", y:");
GUI_DispDec(TouchState.y,4);
delay_ms(50);
};
}

就这个例子
一直显示 0
底层的 int  GUI_TOUCH_X_MeasureX(void) 和 int  GUI_TOUCH_X_MeasureY(void) 也没有调用
int  GUI_TOUCH_X_MeasureX(void)
{
TOUCH_TYPE_DEF touch;
int i;
i=touch_read(CMD_RDX);
printf("CMD_RDX=%d ",i);
return  touch_read(CMD_RDX);
}

int  GUI_TOUCH_X_MeasureY(void)
{
int i;
i=touch_read(CMD_RDX);
printf("CMD_RDY=%d  ",i);
return  touch_read(CMD_RDY);
}

后面我直接跳过这个步骤  直接在定时器里每10ms 调用  这个函数 GUI_TOUCH_Exec();

然后 int  GUI_TOUCH_X_MeasureX(void) 和 int  GUI_TOUCH_X_MeasureY(void)  个调用了但是打印出来的不是 0  就是  4095
我裸机调用touch_read(CMD_RDX); 都是可以的。
不知道什么问题，头都炸了  ，新人求教啊。
