触摸屏实验, GUI, ui, ISP, ST

我的4.3寸触摸屏按照教程一步一步进行移植的，为何在测试如下函数时，可以显示字符，但点击屏幕时，不会有任何反应？这是为何呢？（以下是从segger官网下载来的测试程序），
实在是找不出其他的原因了，所以希望各位大神给点思路...

void MainTask(void) {

      GUI_PID_STATE TouchState;
      int xPhys;
      int yPhys;
      GUI_Init();

      // // Check if recommended memory for the sample is available //

      if (GUI_ALLOC_GetNumFreeBytes() < RECOMMENDED_MEMORY) {

            GUI_ErrorOut(&quot;Not enough memory available.&quot;);
            return;
      }

      GUI_CURSOR_Show();
      GUI_CURSOR_Select(&GUI_CursorCrossL);
      GUI_SetBkColor(GUI_WHITE);
      GUI_SetColor(GUI_BLACK);
      GUI_Clear();
      GUI_DispString(&quot;Measurement of
A/D converter values&quot;);

      while (1) {
            GUI_TOUCH_GetState(&TouchState); // Get the touch position in pixel
            xPhys = GUI_TOUCH_GetxPhys(); // Get the A/D mesurement result in x
            yPhys = GUI_TOUCH_GetyPhys(); // Get the A/D mesurement result in y //
            // Display the measurement result //
            GUI_SetColor(GUI_BLUE);
            GUI_DispStringAt(&quot;Analog input:
&quot;, 0, 20);
            GUI_GotoY(GUI_GetDispPosY() + 2);
            GUI_DispString(&quot;x:&quot;);
            GUI_DispDec(xPhys, 4);
            GUI_DispString(&quot;, y:&quot;);
            GUI_DispDec(yPhys, 4); // // Display the according position //
            GUI_SetColor(GUI_RED);
            GUI_GotoY(GUI_GetDispPosY() + 4);
            GUI_DispString(&quot;
Position:
&quot;);
            GUI_GotoY(GUI_GetDispPosY() + 2);
            GUI_DispString(&quot;x:&quot;);
            GUI_DispDec(TouchState.x,4);
            GUI_DispString(&quot;, y:&quot;);
            GUI_DispDec(TouchState.y,4); // // Wait a while //
            GUI_Delay(100);
      };
}
