Add some sizzle to your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection and a capacitive touchscreen.

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 capacitive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

This shield is the capacitive version. This touchscreen doesn"t require pressing down on the screen with a stylus, and has a nice glossy glass cover. It is a single-touch display.

This shield uses SPI for the display and SD card and is easier to use with UNO, Mega & Leonardo Arduino"s. The capacitive touchscreen controller uses I2C but you can share the I2C bus with other I2C devices.

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.

This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. This shield needs fewer pins than our v1 shield, so you can connect more sensors, buttons and LEDs: 5 SPI pins for the display, 2 shared I2C pins for the touchscreen controller and another pin for uSD card if you want to read images off of it.

The display uses digital pins 13-9. Touchscreen controller requires I2C pins SDA and SCL. microSD pin requires digital #4. That means you can use digital pins 2, 3, 5, 6, 7, 8 and analog 0-5. Pin 4 is available if not using the microSD

You can display bitmap images stored on the microSD card on the display. The shield is plug-and-play, assembled and ready to go. It uses a few I/O pins, which are:

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.

The first part of this three-part series discussed common touchscreen technologies and their typical use-cases. Then, the second part investigated a few readily available and affordable touch display options for makers and hobbyists. This article documents how to get started with one of the recommended Arduino-compatible 2.8” resistive touchscreens from part two.

The TFT display I use contains a resistive overlay, which allows users to control an Arduino-based project with touch inputs. The display controller that comes with the touchscreen supports a few different communication methods. However, I’ll only outline two of them as I find these to be the most useful. The first method uses eight parallel communication lines to transmit pixel data from the Arduino to the display. I recommend using this method in multimedia applications where the Arduino needs to transfer a lot of pixel data.

Note that I used the SPI method to send data from the Arduino to the display. Either way, in addition to the pixel data lines, you’ll further need to employ two additional digital I/O lines and two more analog pins of the Arduino if you want to add resistive touch detection to your project. In addition, this touchscreen module comes with a built-in micro SD card reader I won’t discuss further in this article.

You have to install two libraries before you can send image data to the TFT display. First, use the Arduino IDE’s built-in library manager to download the Adafruit ILI9341 library. This package handles low-level communication between the Arduino and the display controller IC. Then, download the Adafruit_GFX library. The second library contains helpful code for drawing graphics primitives such as simple shapes and text. I recommend you read this article if you don’t know how to use the library manager in the Arduino IDE.

This short test program first initializes the TFT display in the setup()-function. Then, I defined a few helper methods. The resetAndClearScreen()-method resets the display’s rotation and erases all previously drawn pixels. The next function is drawIntroText(). It prints a short status message in the top left corner of the display. Lastly, drawTouchButton() creates a rectangle at the specified position with the given width and height. Then, the method places a string at the center of the previously drawn rectangle. As the name suggests, I’ll later use these rectangles to detect user inputs. The loop()-method refreshes the screen twice a second. But because there’s no interactivity built into the program yet, users can’t change what the screen displays at this point.

To use the resistive touch capabilities of this display, download the Adafruit_TouchScreen library using the Arduino IDE’s built-in library manager. The example code from above prints a few lines of text and then draws two touch buttons. Next, we’ll have to detect when a user presses one of the buttons. If that happens, the Arduino should refresh the screen and draw all the components using different colors. Therefore, I added the following method to detect whether a user touched one of the buttons:

The touchedWithin()-function is easy to understand. The first parameter represents the coordinates of the detected input. Then, the helper method checks whether these x and y coordinates are within the button’s dimensions.

Before making the previously discussed calls to the various draw-functions, the loop() method also checks whether the user touched the resistive screen. The TSPoint class contains a z-value we can use to determine how hard a user pressed down on the screen. This z-value is also perfect for preventing the Arduino from detecting unwanted inputs. If the z-value is greater than a fixed threshold value, the Arduino detects a touch input. The code then calls the touchedWithin()-function to determine whether the user pressed one of the buttons.

Arduino-compatible touchscreens allow you to quickly add a touchscreen to your existing or new DIY projects. Simple-to-use libraries let you get the display up and running in practically no time. The screen I used offers a few ways for devices to send pixel data to it. A parallel interface allows you to achieve higher screen refresh rates, which might be essential in multimedia applications. The parallel interface is also perfect for MCUs with a large number of I/O pins. The SPI method, on the other hand, is a bit slower compared to parallel communication. It, however, allows you to cut down on the number of required I/O pins, which is the preferred option in most Arduino projects.
