Ian Weston / Mbed 2 deprecated ILI9340_Driver

Demo project to demonstrate that ILI9340 display driver and graphics library. very simple but a good starting point for any project using such a display. Please use this to thoroughly enjoy yourself and make your projects cool!

Dependencies:   ILI9340_Driver_Lib mbed

About the Driver:

This driver will drive any display that uses an ILI9340 display controller in SPI mode - such as the adafruits 2.2" 240 x 320 display found here: http://www.adafruit.com/products/1480

All this code has been ported from other peoples hard work - Thanks to All !

dextorslabs 0:9c462c65176a 2 ILI9340_Driver v1.0 26.05.14 Ian Weston
dextorslabs 0:9c462c65176a 3
dextorslabs 0:9c462c65176a 4 Driver and integrated graphics library for displays that use the
dextorslabs 0:9c462c65176a 5 ILI9340 controller in SPI mode.
dextorslabs 0:9c462c65176a 6
dextorslabs 0:9c462c65176a 7 The code was prted from several sources, the driver section
dextorslabs 0:9c462c65176a 8 was completely ported from the Adafruits Arduino source code, and
dextorslabs 0:9c462c65176a 9 the graphics functions were ported from the Adafruits GFX library
dextorslabs 0:9c462c65176a 10 and some elements were ported from code by Elmicros seeduio port.
dextorslabs 0:9c462c65176a 11
dextorslabs 0:9c462c65176a 12 Future revisions will include more advanced graphics functions.
