Tutorial: How to use the Super Touch 2.4 Inch TFT Touch Screen LCD Display

The 2.4 inch TFT Touch Screen LCD display is a useful component for Arduino projects that require interactive graphical display. This tutorial will guide you through the installation and connection of the display to your circuit.

What you need

• Arduino Uno or compatible
• USB cable
• Pull-up resistors (check the datasheet)
• Breadboard wire
• Jumpers

Steps

1. Connect the display connectors to the Arduino circuit following the datasheet.
2. Check that all pins are correctly connected and that there are no short circuits.
3. Install the Adafruit_GFX library through the Arduino IDE.
4. Install the Adafruit_ILI9341 library following the datasheet instructions.
5. Upload the example sketch provided by the library to your Arduino.
6. Open the Serial Monitor to view any error messages or debug information.
7. Test the touch screen functionality with a simple test program.
8. Customize the application to your needs.

Example code

// Includere le librerie necessarie
#include <Adafruit_GFX.h>
#include <Adafruit_ILI9341.h>

// Definire il pin di reset del display
#define TFT_RESET_PIN 9

// Creare un'istanza del display
Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC, TFT_RESET_PIN);

void setup() {
  // Inizializzare il display
  tft.begin();
  tft.fillScreen(ST77XX_BLACK);
}

void loop() {}

Mini project

Create a simple digital clock that displays the time and date on the TFT display. Use the touch screen buttons to navigate through the settings.
