This is our 2.4 inch TFT LCD Display forArduino Uno that will spice up your Arduino project with a touchscreen display shield with built in microSD connection. This TFT display is 2.4″ diagonal with 4 white-LED backlight and 240×320 pixels. It has way more resolution than a black and white 128×64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

Hello, in this tutorial I planned to test different functions of the TFT LCD shield but I encountered few problems and decided to show you some solutions first, so the usual tutorial about this shield will follow up later.
This is the shield I’m using it’s 2.4″ screen, it can work with Arduino Uno, Leonardo, Duemilanove, Mega… and has a slot for SD card you can use it to store BMP pictures and display them.
If it works okay, you can now try the “tftpaint” example to try your touch functions, if it works correctly congratulations, but since you came here, you probably have the touch screen problem, and it’s due to manufacturers keep changing the pins locations.
After this re-upload the code of the paint to your board, and I hope the touch screen is now detected, if it works okay then congratulations otherwise continue the tutorial.

The 2.4 inch TFT LCD Touch Display Shield for Arduino Uno is fully assembled, tested and ready to go. Add the touch display without wiring, no soldering! Simply plug it in and load up a library – you ‘ll have it running in under 10 minutes! Works best with any classic Arduino ATMEGA328 Board
So spice up your Arduino UNO project with a beautiful large touchscreen display shield with a built-in microSD card connection. This TFT display is big (2.4″ diagonal) bright (4 white-LED backlights) and colorful (18-bit 262,000 different shades)!
The Display comes with 240×320 pixels with individual pixel control. It has way more resolution than a black and white 128×64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.Interfacing Diagram:
Spice up your Arduino project with a beautiful touchscreen display shield with built in microSD card connection. This IPS TFT display is 2.4" diagonal and colorful (18-bit 262,000 different shades)! 240x320 pixels with individual pixel control. As a bonus, this display has a optional capacitive touch panel and resistive touch panel with controller XPT2046 attached by default.
The shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up our library - you"ll have it running in under 10 minutes! Works best with any classic Arduino (UNO/Due/Mega 2560).
This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. You can connect more sensors, buttons and LEDs.
Of course, we wouldn"t just leave you with a datasheet and a "good luck!" - we"ve written a full open source graphics library at the bottom of this page that can draw pixels, lines, rectangles, circles and text. We also have a touch screen library that detects x,y and z (pressure) and example code to demonstrate all of it. The code is written for Arduino but can be easily ported to your favorite microcontroller!
1.2.4 inch arduino shield with resistive touch panel could only support Due board. It can support DUE,UNO,MEGA2560 boad if matched with capacitive touch panel.
2.If you"ve had a lot of Arduino DUEs go through your hands (or if you are just unlucky), chances are you’ve come across at least one that does not start-up properly.The symptom is simple: you power up the Arduino but it doesn’t appear to “boot”. Your code simply doesn"t start running.You might have noticed that resetting the board (by pressing the reset button) causes the board to start-up normally.The fix is simple,here is the solution.
2.4 inch TFT LCD Touch Screen Shield for Arduino UNO R3 Mega2560The shield is fully assembled, tested and ready to go. No wielding, no solder! Simply plug it in and load up our library - you"ll have it running in under 10 minutes! Works best with any classic UNO. This shield does work with the Mega but its going to be half the speed of the Uno-type boards because of the way the Mega rearranges all the pins (there is no way to get around this!) This shield is Leonardo-compatible
