Please see the DT028CTFT for reference designs. The schematics between the A and the C are the same with the exception that the A does not have the IPS interface.

In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.
As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.
Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.
I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.
After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.
So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

With four bright white LED backlight and 240 x 320 pixels with individual RGB pixel control, this colour 2.8in. TFT display features a resistive touchscreen for fingertip detection across the entire screen surface. The workload is lifted from the microcontroller by a built-in controller equipped with RAM buffering, and the display board has two modes: 8-bit and SPI.

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (2.4″ diagonal) bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades)! 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.

Let"s get started with this creative Arduino project, where you"ll learn about the TFT LCD touch screen and how to use it to create your own colourful calculator. For a basic understanding of touch screen & LCD, a cheap TFT 2.4" Arduino shield is used to create this project. For creating a similar project, one should follow the steps and edit the code for better understanding.
The shield connects ILI9341"s data pins 0-7 to Arduino"s digital pins 2-8 (allowing parallel communication, not SPI. ILI9341"s RESET goes to Arduino analog pin A4. CS (chip select) to A3. RS (CD command/data) to A2. WR and RD to A1 and A0.
ILI9341 is integrated inside the display. It drives the display and has nothing to do with the touchscreen (Although the shield connects some pins of ILI9341 together with pins of the touchscreen).
first, you have to send a command to ILI9341 and then write or read data/parameters. CS pin has to be LOW during the communication, WR rising from LOW to HIGH tells ILI9341 to read byte on data pins.ILI9341 interprets input byte as a command (if RS=0) or as data/parameter (RS=1).
To read a byte from ILI9341 after sending a read command (e.g. 09h - Read Display Status) set RD from HIGH to LOW, so ILI9341 outputs data until RD returns HIGH.
You can also find an SD card slot at the bottom of the module shown above, which can be used to load an SD card with BMP image files, and these images can be displayed on our TFT LCD screen using the Arduino Program.
The 2.4” TFT LCD screen is a perfect Arduino Shield. You can directly push the LCD screen on top of the Arduino Uno and it will perfectly match with the pins and slid in through. However, as matters of safety cover the programming terminal of your Arduino UNO with some insulator, just in case if the terminal comes in contact with your TFT LCD screen.

Alibaba.com offers 235 tft lcd shield products. About 39% % of these are lcd modules, 1%% are mobile phone lcds, and 1%% are mobile phone motherboard.

So after half a days soldering, I fire up the board and excellent, the ILI9341 is running at a clock speed of 100mhz (not scoped), lightning fast! Dropped the speed to a more reasonable 20mhz and left overnight for a board test (i always do this, as i have lipos connected etc and like to see if there are any heat issues etc after a 24h run). Found no issues the next morning, graphics test still running so powered off the device.
Powered back up after my return from work @20mhz and the graphics test worked fine. Enabled my SD circuitry (solder jumpers), reran the test and both the ILI9341 and SD were both running sweet.
No changes made, powered up on the third day, and nothing but a white screen on the ILI9341? So i say, must have blew the t4 some how. Hot air removed the t4, on goes the new one and again a few runs later and i get a white screen again? Checked all my pin assignments, voltages and they are all good.
To confirm, I had the T4 intermittently working on both the adafruit ili9341 library and the optimised ili9341_t3. I"ve been through 3 T4s and I have 5 different ILI934 displays. (all give the same results, pull ups, no pullups, removed sd circuitry, ran the T4 at 5v I"ve tried it all!)

This TFT display is 3.2" diagonal with a bright 4 white-LED backlight with a resolution of 320x240. It has way more resolution than a black and white 128x64 display. As a bonus, this display comes with a resistive touchscreen attached to it already, so you can use the stylus on the screen.
