Overview
The Arduino 2.8”TFT Touch Shield V2 is designed for all the Arduino compatible boards. It works in 3.3V voltage level. It can be directly plugged on the Arduino and other compatible boards. It will offer display, touch and storage functions for the Arduino board.
NOTE: this screen adopts new chip, thus the old library is not applicable. Please use the New Library.

The Arduino 2.8 TFT Touch shield uses the ILI9341 controller , it support 8bit data interface. The touch IC is TSC2046.
Operation voltage level setting switch
When using the Arduino 2.8 TFT Touch shield with 5V operation level development board – like the Arduino UNO, Arduino MEGA and so on, set the operation voltage level switch to 5V side.
When using the Arduino 2.8 TFT Touch shield with 3.3V operation level development board – like the Iteaduino BT, leaf maple, chipKit UNO and so on, set the operation voltage level switch to 3.3V side.
Software
This shield is compatible with UTFT library for Arduino, chipKit and their compatible boards. You can down load the library here: http://www.rinkydinkelectronics.com/library.php?id=51
Instruction
First, download the UTFT library from Henning, extract the library in the libraries folder. Assure that this is the only UTFT library in your Arduino IDE. http://www.rinkydinkelectronics.com/library.php?id=51
Second, open the file Arduino\libraries\UTFT\hardware\avr\HW_AVR_defines.h, comment out the definition about shield, and save the file.
#define USE_UNO_SHIELD_ON_MEGA 1
Now, open IDE, select UTFT AVR demo
Before upload to your Mega or UNO, you need to modify some parameters. The original parameter of demo shall be replaced to (ITDB28,A5,A4,A3,A2)
Now, you can upload the demo to Mega/UNO. Suggest that plug the LCD shield in your Mega/UNO while demo uploading. If not, you'd better press the reset button after demo uploading.
Note
Note: This shiled is 100% compatible with ITeaduino, Simplecortex. But not 100% compatible with Arduino UNO because of its big USB connecter socket.
