dextorslabs 0:ea46340642a9 2 ILI9340_Driver v1.0 26.05.14 Ian Weston
dextorslabs 0:ea46340642a9 3
dextorslabs 0:ea46340642a9 4 Driver and integrated graphics library for displays that use the
dextorslabs 0:ea46340642a9 5 ILI9340 controller in SPI mode.
dextorslabs 0:ea46340642a9 6
dextorslabs 0:ea46340642a9 7 The code was prted from several sources, the driver section
dextorslabs 0:ea46340642a9 8 was completely ported from the Adafruits Arduino source code, and
dextorslabs 0:ea46340642a9 9 the graphics functions were ported from the Adafruits GFX library
dextorslabs 0:ea46340642a9 10 and some elements were ported from code by Elmicros seeduio port.
dextorslabs 0:ea46340642a9 11
dextorslabs 0:ea46340642a9 12 Future revisions will include more advanced graphics functions.
