For 8051 microcontroller user,we prepared the detailed tutorial such as interfacing, demo code and development kit at the bottom of this page.

I"ve been looking for a product for my 8-bit cpu project and I liked the look of this screen. I was impressed that the claims on the Amazon page says it works with an Arduino mega 2560, so I bought a screen and an Alegoo mega 2560. My project depends the ability to read sn SD card. I currently have an external reader, which may or may not work. However with this TFT screen great I would have a screen and an SD card reader all in one!

So to get the screen working I bought a genuine Uno (wasn"t going to buy an Elegoo clone. Was annoyed with them at this time). The Uno arrived and yes the SD card works. The product works well with an Arduino Uno, but not a Mega 2560.

I have looked over the Amazon web page a few times and I don"t see any indication the SD card part of the screen will work with an Arduino Mega 2560. Another annoyance now is that the screen is dedicated to using the Uno. The Uno has only 1 or 2 IO pins remaining to connect to external devices,but the screen covers them over.

Welcome to another Arduino video tutorial! In this video, we are going to take a first look at this 2.8” Color TFT Touch display! It is a big, low-cost touch display which is very easy to use. Without any further delay, let’s get started.

Hello guys, I am Nick and welcome to educ8s.tv a channel that is all about DIY electronics projects with Arduino, Raspberry Pi, ESP8266, ESP32 and other popular boards. If you are new here, welcome, be sure to subscribe and check the previous videos on the channel.

Today we are going to learn how to drive the 2.8” Touch display with the ILI9341 driver with an Arduino Uno and an ESP32 board. First of all, let’s take a close look at the display itself. The display is big, and it offers a resolution of 320×240 pixels. Compared to one of my favorites displays, the 1.8” Color TFT display you can see it a lot larger. The screen also offers touch functionality which is an added bonus and an SD card slot at the back. It uses the SPI interface, so the connection with the Arduino is very straightforward. The cost of the display is relatively low; it costs around 11$ which in my opinion is a fair price for what this display offers.

Another thing I like about this display is that it does not come as a shield like the touch display we were using so far. This way, we can connect the display to any board, the Arduino Pro mini, the STM32, the ESP8266 and the ESP32. This is very important because we now have a low-cost display that we can use with every board. Until now, the only touch display we could use with these boards were the Nextion displays which are more expensive, and to be honest even though I use them from time to time, I don’t really like them.

Now let’s see how to connect this display to an Arduino Uno. The first 9 pins of the display are the power pins and the SPI pins. So, if we connect only the first 9 pins of the display, we can use it as a regular display without touch functionality. The display uses 3.3-volt logic levels and unfortunately, it is not 5V tolerant. So, we need to use some 10K resistors if we want to drive it with a board that uses 5V logic levels like the Arduino Uno.

As you can see, we have connected Vcc to 5V of the Arduino Uno and the SPI pins of the display to the hardware SPI pins of the Arduino Uno. Let’s load a demo sketch now. As you can the 8bit Arduino Uno with only 2KBs of RAM can drive this big display! But as you can see it is very slow in updating the screen. It takes many seconds to update the whole screen which is a pity. It can display text with more speed though. It is obvious that the Arduino Uno is not enough to drive a display with such a high resolution. It is obvious that we need a more powerful board to drive this display effectively.

But can we build a useful project using this display? I wanted to find out, so I decided to build a simple real-time clock and temperature monitor. I added a DS3231 RTC module, and I modified the code of a previous project to use the new bigger display. You can find the code of the project in a link in the description below. The result is not that bad as the demo sketch. The project works fine, but of course, there is a small delay when the values on the screen are updated. In my opinion, this project demonstrates that we can use this display with an 8bit Arduino only on very simple projects that update the screen rarely.

Let’s now connect the display to an ESP32 board. If you are not familiar with it, the ESP32 is a very fast and inexpensive Arduino compatible board. I prepared a detailed review of this board a few months ago; you can watch it by clicking on the card here. Since the ESP32 board uses 3.3V logic levels, we don’t need any resistors to drive the display. So, if we don’t need the touch functionality, we connect the display according to this schematic diagram.

If we upload the same sketch that used before on the Arduino Uno, we can see the ESP32 is extremely fast. It can update the display, draw graphics and complete the demo sketch way faster than the Arduino Uno.

Let’s now see the software side of the project. In order to use this display with Arduino, we need to install the Adafruit ILI9341 driver and the familiar Adafruit GFX library if we don’t use the touch functionality. If we want to use the touch functionality, we have also to install the URtouch library. You can find links to all the libraries needed along with the code of the demo programs I showed you in the description below.

I am trying to make a truly Universal Remote Control out of this mess. I just got the Arduino Uno & the Display and put it together and there are NO pins left to operate an IR LED.

Can this 2.8" elegoo display play video at all? I"m trying to make a unit that an older woman, in her 80"s can play a video on it, if I set it up correctly? This is for a really good cause, I desperately need help, this is super important. Helping elderly folks with modern technology is tough. But I really need it to be able to play a video off the SD card if possible. Any help would be super highly appreciated.ReplyUpvote

Hello,please post our code also ..the screen driver must be known and that info must be known in order to get these things to work correctly..you show your code and then the vid blurs..Someone needs to write a pdf teaching how ,what ,when and why concerning these screens I would gladly pay $10.00 and I am sure others would too.I have 3 different tftlcds only 1 works its for the mega and Bomer has a lib for it,I am really considering use of Nextion units from now on 4 pins easy programming but higher cost...also the small cell phone screens use spi mode and are real easy to set up and use

The program runs and nothing is displayed but a white screen. when I open the COM4 I see that when I hit the screen numbers appear to calibrate the screens position so it is registering but not showing up on the LCD. please help me before I pull all my hair out.1

I"m thinking I need an Arduino Mega to do what I want - a Universal Remote. Because after mounting the display there are NO pins left for anything else.0

Thank you for the instructable. I"v been trying to build a DIY smartphone but couldn"t get the code or libraries for the touch screen. Now i can finally build it. Thanks.0

I"m having issues getting this display to work on my Arduino 101 board with the libraries that are suggested - errors in compiling seem to indicate that the board type isn"t supported in the Adafruit_TFTLCD library. Here"s a representative error:

I finally got the touchscreen to work correct using your links to the libraries. Found out that this specific TFT display module uses pin 6 & 7 for touch sensor, instead of the standard 4 & 5.0

I never received a response on this, so went through the painful process of copying code from the video. It can be found here for others that might need it. Not that this has some minor changes, but is fully functional and I will continue to refine: https://github.com/siliconghost/Arduino_2.8in_TFT_wSD

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades)! 240x320 pixels with individual pixel control. It has way more resolution than a black and white 128x64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

- Arduino UNO R3 and its compatible board can use it directly to display characters, graphics and BMP format images. And touch controlling is available;

In this guide we’re going to show you how you can use the 1.8 TFT display with the Arduino. You’ll learn how to wire the display, write text, draw shapes and display images on the screen.

The 1.8 TFT is a colorful display with 128 x 160 color pixels. The display can load images from an SD card – it has an SD card slot at the back. The following figure shows the screen front and back view.

This module uses SPI communication – see the wiring below . To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later.

The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. We also use the TFT library to write and draw on the display.

The 1.8 TFT display can load images from the SD card. To read from the SD card you use the SD library, already included in the Arduino IDE software. Follow the next steps to display an image on the display:

In this guide we’ve shown you how to use the 1.8 TFT display with the Arduino: display text, draw shapes and display images. You can easily add a nice visual interface to your projects using this display.

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.

As the code is a bit longer and for better understanding I will post the source code of the program in sections with description for each section. And at the end of this article I will post the complete source 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.

Ok next is the RGB LED Control example. If we press the second button, the drawLedControl() custom function will be called only once for drawing the graphic of that example and the setLedColor() custom function will be repeatedly called. In this function we use the touch screen to set the values of the 3 sliders from 0 to 255. With the if statements we confine the area of each slider and get the X value of the slider. So the values of the X coordinate of each slider are from 38 to 310 pixels and we need to map these values into values from 0 to 255 which will be used as a PWM signal for lighting up the LED. If you need more details how the RGB LED works you can check my particular tutorialfor that. The rest of the code in this custom function is for drawing the sliders. Back in the loop section we only have the back button which also turns off the LED when pressed.

In order the code to work and compile you will have to include an addition “.c” file in the same directory with the Arduino sketch. This file is for the third game example and it’s a bitmap of the bird. For more details how this part of the code work  you can check my particular tutorial. Here you can download that file:

This is a 2.8" Arduino Touch Screen Tutorial with the ILI9325 driver. Is this Arduino touch display a good option for your Arduino projects? Keep watching in...

Arduino 2.8"" TFT Touch Shield is an Arduino UNO/ Mega compatible multicolored TFT display with a touch-screen and SD card socket. It is available in an Arduino shield compatible pinout for attachment. The TFT driver is based on ILI9325DS with 8bit data and 4bit control interface.

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades)! 240x320 pixels with individual pixel control. It has way more resolution than a black and white 128x64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen. (We also have a capacitive-touch version of this shield here)

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/Duemilanove/Diecimila). Solder three jumpers and you can use it at full speed on a Leonardo or Mega as well.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!" - we"ve written a full open source graphics library 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!
