TouchScreen_Test实验
===========================================================================================
本实验实现触摸屏的控制，当触摸液晶屏时，通过串口输出坐标位置信息。本例程有两种运行方式。
TouchScreen_Test_In_RAM         将程序下载到SDRAM中调试。
TouchScreen_In_Flash            将程序烧写到Nor Flash中。上电自动运行。
===========================================================================================
程序运行成功之后。
超级终端上将显示：

  Touch Screen coordinate Rang in:
   (Xmin,Ymin) is :(0000,0000)
   (Xmax,Ymax) is :(0000,0000)

  To use current settings. Press N/n key. 

  Want to Set Again(Y/N)?

  按下y进行坐标定位，用触摸笔在触摸显示屏的任意对角进行坐标定位。
  Touch TSP's Cornor to ensure Xmax,Ymax,Xmax,Xmin

  User touch coordinate(X,Y) is :(1023,1023)
  User touch coordinate(X,Y) is :(0085,0191)

  Touch Screen coordinate Rang in:
   (Xmin,Ymin) is :(0085,0191)
   (Xmax,Ymax) is :(1023,1023)
  To use current settings. Press N/n key. 
  Want to Set Again(Y/N)? 

  按下n键，进行触摸屏测试：
  Pixel: 320 X 240. Coordinate Rang in: (0,0) - (320,240)
  LCD TouchScreen Test Example(please touch LCD screen)

  此时用触摸笔在显示屏的任一位置点击，可在终端上打印点击的坐标信息：
  X-Posion[AIN1] is 0030     Y-Posion[AIN0] is 0166
  X-Posion[AIN1] is 0082     Y-Posion[AIN0] is 0173
  X-Posion[AIN1] is 0000     Y-Posion[AIN0] is 0150
  X-Posion[AIN1] is 0011     Y-Posion[AIN0] is 0060
  X-Posion[AIN1] is 0039     Y-Posion[AIN0] is 0122
