Ian Weston / ILI9340_Driver_Lib Featured

V1.1 of the ILI9340 driver for SPI with integrated graphics functions.

Dependents:   ILI9340_Driver SDCard_Aitendo_2p2TFT TFT22ok_test_ILI9340_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:ea46340642a9 3
dextorslabs 0:ea46340642a9 4 Driver and integrated graphics library for displays that use the
dextorslabs 1:216d35e347b8 5 ILI9340 controller in SPI mode. Such as the Adafruit 2.2" display.
dextorslabs 0:ea46340642a9 6
dextorslabs 1:216d35e347b8 7 This code has been ported 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.
