  UTFT_SPI.h - Arduino library support for Color TFT LCD Boards
  This is special porting for ArduCAM shield LCD screen. 
  Use SPI bus interface and SSD1289 controller. Only work on 
  ArduCAM shield Rev.C.
  For more information about ArduCAM shield please visit

  This library is the continuation of my ITDB02_Graph, ITDB02_Graph16
  and RGB_GLCD libraries for Arduino and chipKit. As the number of 
  supported display modules and controllers started to increase I felt 
  it was time to make a single, universal library as it will be much 
  easier to maintain in the future.

  Basic functionality of this library was origianlly based on the 
  demo-code provided by ITead studio (for the ITDB02 modules) and 
  NKC Electronics (for the RGB GLCD module/shield).

  This library supports a number of 8bit, 16bit and serial graphic 
  displays, and will work with both Arduino and chipKit boards. For a 
  full list of tested display modules and controllers, see the 
  document UTFT_Supported_display_modules_&_controllers.pdf.

  When using 8bit and 16bit display modules there are some 
  requirements you must adhere to. These requirements can be found 
  in the document UTFT_Requirements.pdf.
  There are no special requirements when using serial displays.

  You can always find the latest version of the library at 
  http://electronics.henningkarlsen.com/

  If you make any modifications or improvements to the code, I would 
  appreciate that you share the code with me so that I might include 
  it in the next release. I can be contacted through 
  http://electronics.henningkarlsen.com/contact.php.
