+/***************************************************************
+    ILI9340_Driver  v1.0    26.05.14    Ian Weston
+    
+Driver and integrated graphics library for displays that use the 
+ILI9340 controller in SPI mode.
+
+The code was prted from several sources, the driver section
+was completely ported from the Adafruits Arduino source code, and
+the graphics functions were ported from the Adafruits GFX library
+and some elements were ported from code by Elmicros seeduio port.
+
+Future revisions will include more advanced graphics functions.
+
+Rough and ready Demo code to for showing the driver and some 
+functions in action.
