/*
UTFT.cpp - Multi-Platform library support for Color TFT LCD Boards
Copyright (C)2015-2018 Rinky-Dink Electronics, Henning Karlsen. All right reserved
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, chipKit boards and select
TI LaunchPads. 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 find the latest version of the library at
http://www.RinkyDinkElectronics.com/
This library is free software; you can redistribute it and/or
modify it under the terms of the CC BY-NC-SA 3.0 license.
Please see the included documents for further information.
Commercial use of this library requires you to buy a license that
will allow commercial use. This includes using the library,
modified or not, as a tool to sell products.
The license applies to all part of the library including the
examples and tools supplied with the library.
