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.

I am trying to find a demo sketch and the correct wiring to connect an OPEN-SMART 2.2” TFT LCD w/ Touch Screen (ILI9225) to an Arduino Uno clone or an Arduino Mega2560 clone. I have searched the web extensively to no avail. I would like to get it working so I could use it on a project I’m trying to make. I am a relative newbie to Arduino so I don’t know enough about C++ to alter some other sketch to make it work with this LCD and I have not been able to find a data sheet on it. If someone could direct me to the correct location for the wiring and sketch I would be most appreciative. By the way, the LCD has 16 pins on one end; they are: GND, 3V3, CS, RS(X-), WR(Y+), RD, RST, LED, DB0 to DB6(X+), DB7(Y-). I don’t know which of these pins to connect to which pins on the Uno or Mega.

When I purchased the LCD I was under the belief that there was multiple instances of using this LCD on the Web and certainly wiring schematics and sketches that I could use. Well, that’s just NOT the case, or I couldn’t find any. Had I known how tough it is to use this LCD I would not have purchased it. So, again, any help would be much appreciated.

Look at the back of the 2.2inch TFT LCD Display Module Touch Screen Shield from OpenSmart. These are not the same pins we saw with the 2.4inch ILI9341 which followed the MCUFRIEND layout.

Let"s go through the pinouts and see what they are. The UART and I2C ports are available and they are wired out to the face of the shield. A few pins are unused. The data leads for the LCD screen are spread about. Schematics say the SPI pins are standard.

When I ordered my board the vendor gave me a link to GoogleDocs where I downloaded a zip file. The Zip file was for more than one product. Inside the ILI9225 shield folder were two arduino libraries for Arduino TouchScreen and UTFT.

When you restart your Arduino IDE there will be menus for TouchScreen and UTFT added to your examples. Look inside the examples folder in the library and you will see several TFT screen products are listed.

Let"s open the example TFT_2in2_176x220_Demo and compile to make sure everything is working. Error messages do contain useful information about what you have to repair.

Upload the sketch and the Demo program will run on the screen. There are two more example sketches for our shield: TFT_2in2_Show_bmp and TouchScreen_2inch_9225.

Let us try another sketch. This one is very basic and you should change parameters around to see what you get. Change colours, change locations.// Demo of Graphics on OpenSmart ILI9225 2.2inch shield 176x220

We are using release 2.78 of the UTFT library from 2014. OpenSmart has modified the library to support their boards. That is why they gave me a download.

The UTFT library was produced by Rink Dink Electronics and you can download the latest release 2.83 from 2018. Unfortunately, this version of the library will not work with our board. It does not have files to work with the ILI9225. But we can still use the examples if we modify them.

Open the sketch UTFT_ViewFont and find the constructor. Comment out the line UTFT myGLCD(ITDB32S, 38, 39, 40, 41) because it is for a different display type on a different Arduino board.

No! For about the price of a familiar 2x16 LCD, you get a high resolution TFT display. For as low as $4 (shipping included!), it"s possible to buy a small, sharp TFT screen that can be interfaced with an Arduino. Moreover, it can display not just text, but elaborate graphics. These have been manufactured in the tens of millions for cell phones and other gadgets and devices, and that is the reason they are so cheap now. This makes it feasible to reuse them to give our electronic projects colorful graphic displays.

There are quite a number of small cheap TFT displays available on eBay and elsewhere. But, how is it possible to determine which ones will work with an Arduino? And what then? Here is the procedure:ID the display. With luck, it will have identifying information printed on it. Otherwise, it may involve matching its appearance with a picture on Google images. Determine the display"s resolution and the driver chip.

Find out whether there is an Arduino driver available. Google is your friend here. Henning Karlsen"s UTFT library works with many displays. (http://www.rinkydinkelectronics.com/library.php?i...)

Load an example sketch into the Arduino IDE, and then upload it to the attached Arduino board with wired-up TFT display. With luck, you will see text and/or graphics.

We"ll begin with a simple one. The ILI9163 display has a resolution of 128 x 128 pixels. With 8 pins in a single row, it works fine with a standard Arduino UNO or with a Mega. The hardware hookup is simple -- only 8 connections total! The library put together by a smart fella, by the name of sumotoy, makes it possible to display text in multiple colors and to draw lines.

Note that these come in two varieties, red and black. The red ones may need a bit of tweaking to format the display correctly -- see the comments in the README.md file. The TFT_ILI9163C.h file might need to be edited.

It is 5-volt friendly, since there is a 74HC450 IC on the circuit board that functions as a level shifter. These can be obtained for just a few bucks on eBay and elsewhere, for example -- $3.56 delivered from China. It uses Henning Karlsen"s UTFT library, and it does a fine job with text and graphics. Note that due to the memory requirement of UTFT, this display will work with a standard UNO only with extensive tweaking -- it would be necessary to delete pretty much all the graphics in the sketch, and just stay with text.

This one is a 2.2" (diagonal) display with 176x220 resolution and parallel interface. It has a standard ("Intel 8080") parallel interface, and works in both 8-bit and 16-bit modes. It uses the S6D0164 driver in Henning Karlsen"s UTFT library, and because of the memory requirements of same, works only with an Arduino Mega or Due. It has an SD card slot on its back

This one is a bit of an oddball. It"s a clone of the more common HY-TFT240, and it has two rows of pins, set at right angles to one another. To enable the display in 8-bit mode, only the row of pins along the narrow edge is used. The other row is for the SD card socket on the back, and for 16-bit mode. To interface with an Arduino ( Mega or Due), it uses Henning Karlsen"s UTFT library, and the driver is ILI9325C. Its resolution is 320x240 (hires!) and it incorporates both a touch screen and an SD card slot.

Having determined that a particular TFT display will work with the Arduino, it"s time to think about a more permanent solution -- constructing hard-wired and soldered plug-in boards. To make things easier, start with a blank protoshield as a base, and add sockets for the TFT displays to plug into. Each socket row will have a corresponding row next to it, with each individual hole "twinned" to the adjacent hole in the adjoining row by solder bridges, making them accessible to jumpers to connect to appropriate Arduino pins. An alternative is hard-wiring the socket pins to the Arduino pins, which is neater but limits the versatility of the board.

In step 5, you mention that the TFT01 display can"t be used with the UTFT library on an Arduino Uno because of its memory requirements. It can - all you have to do is edit memorysaver.h and disable any display models you"re not using.

Tho I realize this is quickly becoming legacy hardware, these 8,16 bit parallel spi with 4 wire controller 3.2in Taft touch display 240x380. It has become very inexpensive with ally of back stock world wide so incorporating them into any project is easier then ever. Sorry to my question. I’m having difficulty finding wiring solution for this lcd. It is a sd1289 3.3 and 5v ,40 pin parallel 8,16 bit. I do not want to use a extra shield,hat or cape or adapter. But there’s a lot of conflicting info about required lvl shifters for this model any help or links to info would be great .. thank you. I hope I gave enough information to understand what I’m adoing

Of course, we wouldn"t just leave you with a datasheet and a "good luck!".Here is the link for 2.2"TFT Shield with Libraries, Examples.Schematic Diagram for Arduino Due,Mega 2560 and Uno.For 8051 microcontroller user,we prepared the detailed tutorial such as interfacing, demo code and Development Kit at the bottom of this page.

HY-TFT220 is a 2.2 inch TFT LCD Screen module, 220*176 (resolution), 65K color, 28pins interface , not just a LCD breakout, but include the Touch screen, SD card. So it’s a powerful extension module for your project.

This Screen includes a controller HX8340, it’s 8 bit data interface, easy to drive by many MCU like STM32 ,AVR and 8051.HY-TFT220 is designed with a touch controller in it . The touch IC is XPT2046 , and touch interface is included in the 40 pins breakout. Another useful extension in this module is the SD Card socket . It use the SPI mode to operate the SD card, the SPI interface include in the 40pins breakout.

The UTFT library is required to be installed to get this screen model display. This library is especially designed for TFT LCD screen model. The library requires the following connections.

Note: The TFT controller model needs to be declared in the initializing statement. UTFT myGLCD(38,39,40,41) needs to be modified as myGLCD(ITDB22,38,39,40,41) when using Arduino Mega2560.UTFT myGLCD(ITDB22,19,18,17,16) needs to be commented when using Aduino UNO. Otherwise it just show a blank screen. In practice, RS, WR, CS, RSET can be connected to any free pin. But the pin number must be in accord with myGLCD(RS,WR,CS,RST).

The LCD has a 2.2" 4-wire resistive touch screen lying over it. The Touch library needs to be installed to get it works. This library is designed for 2.4’’ TFT, 2.8” TFT LCD screen module.

The default setting is not accurate for 2.2” TFT module, so you need to calibrate when using 2.2” TFT module. A program to calibrate the touch screen is included in the example. If you touch screen is inaccurate, you need to run touch_calibration. Follow the on-screen instruction to calibrate the touch screen. Better not use your finger to calibrate it, use your accessory touch pen to pressure the frontsight with stength. Then record the calibration parameters and apply them in ITDB02_Touch.cpp in your touch screen library.

The TFT display is a kind of liquid crystal display that is connected to each pixel using a transistor and it features low current consumption and backlight. This 2.2-inch full color LCD has a narrow PCB screen. The resolution is 320×280 pixels and it has a four-wire SPI interface and white backlight.
