Georgios Moralis / ILI9340Library

ILI9340 Library based on the Arduino version from Adafruit. It has been tested with a custom STM32F103C8 board.

Porting of the ILI9340 Library from Adafruit. It has been tested on a custom board based on a STM32F103C8 microcontroller.

Please, see the Wiki page on how to use the library
