Added modified version of AdaFruit_ILI9341 library, based on work by Matthias (@madias on the Arduino forum). Also includes a small speed optimization to call nonstandard spi::write(byte) function, as this gives around 20% speed improvement. Note SPI clock rate, chosen my @madias, of DIV_2 is 36Mhz, which exceeds the publish maximum spi clock of 10Mhz, however it seems to work with most devices

This is a library for the Adafruit ILI9341 display products
|
||||||
|
|
||||||
|
This library works with the Adafruit 2.8" Touch Shield V2 (SPI)
|
||||||
|
----> http://www.adafruit.com/products/1651
|
||||||
|
|
||||||
|
Check out the links above for our tutorials and wiring diagrams.
|
||||||
|
These displays use SPI to communicate, 4 or 5 pins are required
|
||||||
|
to interface (RST is optional).
|
||||||
|
|
||||||
|
Adafruit invests time and resources providing this open source code,

To download. click the DOWNLOADS button in the top right corner, rename the uncompressed folder Adafruit_ILI9341. Check that the Adafruit_ILI9341 folder contains Adafruit_ILI9341.cpp and Adafruit_ILI9341.
|
||||||
|
|
||||||
|
Place the Adafruit_ILI9341 library folder your arduinosketchfolder/libraries/ folder. You may need to create the libraries subfolder if its your first library. Restart the IDE
|
||||||
|
|
||||||
|
Also requires the Adafruit_GFX library for Arduino.
