justinkim 0:53f8d6b23687 2 UTFT_SPI.h - Arduino library support for Color TFT LCD Boards
justinkim 0:53f8d6b23687 3 This is special porting for ArduCAM shield LCD screen.
justinkim 0:53f8d6b23687 4 Use SPI bus interface and SSD1289 controller. Only work on
justinkim 0:53f8d6b23687 5 ArduCAM shield Rev.C.

justinkim 0:53f8d6b23687 9
justinkim 0:53f8d6b23687 10 This library is the continuation of my ITDB02_Graph, ITDB02_Graph16
justinkim 0:53f8d6b23687 11 and RGB_GLCD libraries for Arduino and chipKit. As the number of
justinkim 0:53f8d6b23687 12 supported display modules and controllers started to increase I felt
justinkim 0:53f8d6b23687 13 it was time to make a single, universal library as it will be much
justinkim 0:53f8d6b23687 14 easier to maintain in the future.
justinkim 0:53f8d6b23687 15
justinkim 0:53f8d6b23687 16 Basic functionality of this library was origianlly based on the
justinkim 0:53f8d6b23687 17 demo-code provided by ITead studio (for the ITDB02 modules) and
justinkim 0:53f8d6b23687 18 NKC Electronics (for the RGB GLCD module/shield).
justinkim 0:53f8d6b23687 19
justinkim 0:53f8d6b23687 20 This library supports a number of 8bit, 16bit and serial graphic
justinkim 0:53f8d6b23687 21 displays, and will work with both Arduino and chipKit boards. For a
justinkim 0:53f8d6b23687 22 full list of tested display modules and controllers, see the
justinkim 0:53f8d6b23687 23 document UTFT_Supported_display_modules_&_controllers.pdf.
justinkim 0:53f8d6b23687 24
justinkim 0:53f8d6b23687 25 When using 8bit and 16bit display modules there are some
justinkim 0:53f8d6b23687 26 requirements you must adhere to. These requirements can be found
justinkim 0:53f8d6b23687 27 in the document UTFT_Requirements.pdf.
justinkim 0:53f8d6b23687 28 There are no special requirements when using serial displays.
justinkim 0:53f8d6b23687 29

justinkim 0:53f8d6b23687 32
justinkim 0:53f8d6b23687 33 If you make any modifications or improvements to the code, I would
justinkim 0:53f8d6b23687 34 appreciate that you share the code with me so that I might include
justinkim 0:53f8d6b23687 35 it in the next release. I can be contacted through
