This library is based on the Adafruit ILI9341 (see original Adafuit text description below)
It has minor modifications to support STM32 and also one small change to use spi.write(byte) instead of spi.transfer(byte) as this gave
a useful speed improvement.
It has been tested with standard ILI9341 from various suppliers e.g on eBay
This library requires the Adafruit GFC library, https://github.com/adafruit/Adafruit-GFX-Library
An addition example stm32_graphicstest has been added to show how to configure for stm32 - which uses hardware SPI and hence its not possible to
set the SCK MISO and MOSI pins.
_________________________ Original text from Adafruit ____________________________________________
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,

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.
