The Nextion display module is powered by an ARM Cortex-M0 processor and has 16MB of flash memory and 1024 bytes of EEPROM. It also has a real-time clock and supports multiple languages.
Principle of Work:
The LCD 5.0 Nextion Touch TFT Serial Display Panel Module NX8048T050 works by using a combination of hardware and software to display images and interact with the user. Here's a summary of the working principle:
- Hardware: The Nextion display module consists of a TFT LCD screen, a touch panel, a microcontroller, and a communication interface. The microcontroller controls the display and handles user input from the touch panel. The communication interface allows the display module to communicate with a host device, such as an Arduino or Raspberry Pi, using a serial protocol.
- Software: The Nextion display module comes with software that allows users to design their own custom user interfaces using a drag-and-drop interface. The software generates a binary file that is uploaded to the display module's flash memory. This file contains all the graphics, text, and user interface elements that make up the display.
- Interaction: When the display module is connected to a host device, the host sends commands to the display module to update the display and respond to user input. For example, if the user touches a button on the screen, the touch panel sends a signal to the microcontroller, which in turn sends a message to the host device indicating which button was pressed. The host device can then respond by performing a specific action, such as turning on an LED or sending data to a server.
- Customization: The Nextion display module is highly customizable, allowing users to create their own graphics, animations, and user interfaces. The module supports a variety of file formats, including BMP, JPEG, and GIF, and can display images, text, and even video.
Pinout of the Module:
Pinout of the UART Connecter

Applications:
- Home automation systems - the display can be used to provide a user interface for controlling smart home devices, such as lighting, temperature, and security systems.
- Industrial control systems - the display can be used to monitor and control machinery, displaying real-time data and allowing operators to adjust settings as needed.
- Automotive displays - the display can be used in automotive applications, such as navigation systems, media players, and vehicle diagnostics.
- Medical equipment - the display can be used in medical equipment, such as patient monitoring devices, where a clear and easy-to-read display is important.
- DIY electronics projects - the display can be used in hobbyists and DIY electronics projects, such as building your own smartwatch, weather station, or home automation system.
Circuit:
- Connect the Nextion display's VCC pin to both the Arduino's 5V pin and the external 5V power supply's positive terminal.
- Connect the Nextion display's TX pin to the Arduino's RX pin (pin 0).
- Connect the Nextion display's RX pin to the Arduino's TX pin (pin 1).
- Connect the Nextion display's GND pin to the Arduino's GND pin.
- Connect the external 5V power supply's negative terminal to the Arduino's GND pin.
Library:
In the example code using the Nextion.h
library, you don't need to create the button on the display using serial commands from Arduino. Instead, you can create the button directly on the display using the Nextion Editor software, and then use the NexButton
object to register the button with the Arduino code.
To create a button on the display using the Nextion Editor software, follow these steps:
- Open the Nextion Editor software and create a new project.
- Drag and drop a button component onto the canvas.
- In the Properties pane, set the
objname
property to "bt0". - Set the button's text and appearance properties to your liking.
- Save the project and compile it to generate the
.tft
file. - Upload the
.tft
file to the Nextion display using the Nextion Editor software or a microSD card.
Once the button is created on the display and uploaded, you can use the NexButton
object in the Arduino code to register the button and the led_toggle()
function, as shown in the example code using the Nextion.h
library.
Code:
code for the 5.0 Nextion Touch TFT Serial Display Panel Module NX8048T050 with Arduino Uno connected through serial, which will toggle the onboard LED on and off when a button on the display is pressed:
#include "Nextion.h" // Define the Nextion display object NexButton bt0 = NexButton(0, 1, "bt0"); // Define the LED pin int ledPin = 13; void setup() { // Set the LED pin as an output pinMode(ledPin, OUTPUT); // Initialize the Nextion display object nexInit(); // Register the button object and the LED control function bt0.attachPop(led_toggle); } void loop() { // Process any pending communication with the Nextion display nexLoop(nex_listen_list); } // Function to toggle the onboard LED on and off void led_toggle(void *ptr) { digitalWrite(ledPin, !digitalRead(ledPin)); }
This code uses the Nextion.h
library to simplify communication with the Nextion display. It defines a NexButton
object for the button on the display, and registers it with the led_toggle()
function, which toggles the onboard LED on and off.
Note that the led_toggle()
function takes a void *ptr
parameter, which is required by the NexButton
object's attachPop()
function. However, this parameter is not used in this example code. Also, note that the nexLoop()
function processes any pending communication with the Nextion display and must be called periodically in the loop()
function.
