nextion usart hmi tft lcd factory

A few weeks ago, I wrote this article about using a text variable as an array, either an array of strings or an array of numbers, using the covx conversion function in addition for the latter, to extract single elements with the help of the spstr function. It"s a convenient and almost a "one fits all" solution for most use cases and many of the demo projects or the sample code attached to the Nextion Sunday Blog articles made use of it, sometimes even without mentioning it explicitly since it"s almost self-explaining. Then, I got a message from a reader, writing: "... Why then didn"t you use it for the combined sine / cosine lookup table in the flicker free turbo gauge project?"105 editions of the Nextion Sunday blog in a little over two years - time to look back and forth at the same time. Was all the stuff I wrote about interesting for my readers? Is it possible at all to satisfy everybody - hobbyists, makers, and professionals - at the same time? Are people (re-)using the many many HMI demo projects and code snippets? Is anybody interested in the explanation of all the underlying basics like the algorithms for calculating square roots and trigonometric functions with Nextion"s purely integer based language? Are optimized code snippets which allow to save a few milliseconds here and there helpful to other developers?Looking through the different Nextion user groups on social networks, the Nextion user forum and a few not so official but Nextion related forums can be surprising. Sometimes, Nextion newbies ask questions or have issues although the required function is well (in a condensed manner for the experienced developer, I admit) documented on the Nextion Instruction Set page, accessible through the menu of this website. On top of that, there is for sure one of my more than 100 Sunday blog articles which deals not only with that function, but goes often even beyond the usual usage of it. Apparently, I should sometimes move away from always trying to push the limits and listen to the "back to the roots!" calls by my potential readers...Do you remember the (almost) full screen sized flicker free and ultra rapid gauge we designed in June? And this without using the built-in Gauge component? If not, it"s time to read this article first, to understand today"s improvements. The June 2022 version does its job perfectly, the needle movement is quick and smooth, and other components can be added close to the outer circle without flickering since there is no background which needs constantly to be redrawn. But there was a minor and only esthetic weak point: The needle was a 1px thin line, sometimes difficult to see. Thus, already a short time after publishing, some readers contacted me and asked if there were a way to make the needle thicker, at least 2 pixels.Recently, when playing with a ESP32 based NodeMCU 32S and especially with its WiFi configuration, I did as (I guess) everybody does: I loaded an example sketch to learn more about the Wifi library. When you set up the ESP32 as an access point, creating its own wireless network, everything is pretty straightforward. You can easily hard code the Wifi name (SSID) and the password. But what about the client mode ? Perhaps one needs to use it in different environments. And then, a hard coded network name and password are definitively not the best solution. Thus, I thought, why not use a Nextion HMI for a dynamic WiFi setup functionality?Although the Nextion MIDI I/O interface  has been primarily designed as an add-on for Nextion HMI screens to transform these in fully autonomous MIDI devices as shown in previous blog posts here, it is also of great use for any Arduino based electronic music project! Many MIDI projects for Arduino suffer from a lack good hardware support. There are sophisticated code, excellent libraries and an infinity of use cases, but afterwards, things tend not to work in a rather rough environment in the studio or on stage. That"s because two resistors and a few Dupont wires on a breadboard besides the Arduino are not really an interface which could drive your Synth, Sequencer, or Drum machine over a 5m long MIDI cable.

A: Nextion works with many MCUs, but we only offer Library for arduino and Linux. You need to develop Lib for other MCUs, and all instructions must strictly follow Nextion Instruction Set

A: Choose HMI file in Nextion Editor -Click "Compile" and it"ll show "Compile Successful!" in the bottom of software -Choose "File","TFT file output" -Click "Output" and save TFT file.

A: Prepare a SD card ( FAT32 format and less than 32GB) -Copy TFT file from PC to SD card (ensure only one TFT file in it) -Insert SD card into Nextion card slot -Power on Nextion -File uploaded automatically and displays "Update Successed!" after completed -Power off Nextion -Remove SD card -Power on and project will show on Nextion.

HMI Displays are becoming increasingly popular as a result of their intelligence, and NEXTION is one of the major players in HMI Display Production, which has introduced a range of different kinds of Displays at a very affordable cost.

NEXTION offers an advanced level of displays at an affordable cost than any other competitor brand in the market, making them ideal for the one who wants to start some Projects through touch displays. This type of Display has inbuilt audio, video, and animation play functions which makes it smart.

Nextion NX4832T035-3.5″ HMI TFT LCD Touch Display Module is a seamless Human Machine Interface (HMI) solution that provides a control and visualization interface between a human and a process, machine, application, or appliance. Nextion is mainly applied to the Internet of Things (IoT) or consumer electronics field. It is the best solution to replace the traditional LCD and LED Nixie tubes.

The operating Voltage of the Display is lies between 4.75 to 7 V also this TFT Screen Intelligent Display Module with integrated 4-wire Resistive Touch Panel For Arduino DIY NX4832T035 480 x 320 is a powerful 3.5” HMI, which is a member of the Nextion family. The following are some of the features: a 3.5 “TFT 480 x 320 resistive touchscreen, 16M Flash, 65K colors.

This post is an introduction to the Nextion display with the Arduino. We’re going to show you how to configure the display for the first time, download the needed resources, and how to integrate it with the Arduino UNO board. We’ll also make a simple graphical user interface to control the Arduino pins.

Nextion is a Human Machine Interface (HMI) solution. Nextion displays are resistive touchscreens that makes it easy to build a Graphical User Interface (GUI). It is a great solution to monitor and control processes, being mainly applied to IoT applications.

The Nextion has a built-in ARM microcontroller that controls the display, for example it takes care of generating the buttons, creating text, store images or change the background. The Nextion communicates with any microcontroller using serial communication at a 9600 baud rate.

To design the GUI, you use the Nextion Editor, in which you can add buttons, gauges, progress bars, text labels, and more to the user interface in an easy way. We have the 2.8” Nextion display basic model, that is shown in the following figure.

The best model for you, will depend on your needs. If you’re just getting started with Nextion, we recommend getting the 3.2” size which is the one used in the Nextion Editor examples (the examples also work with other sizes, but you need to make some changes). Additionally, this is the most used size, which means more open-source examples and resources for this size.

To get started with Nextion, first you need to install Nextion Editor. Go to https://nextion.itead.cc/, select the Resources tab, Download > Nextion Editor and install Nextion Editor. You can either download the .zip file or the .exe file.

Connecting the Nextion display to the Arduino is very straightforward. You just need to make four connections: GND, RX, TX, and +5V. These pins are labeled at the back of your display, as shown in the figure below.

You can power up the Nextion display directly from the Arduino 5V pin, but it is not recommended. Working with insufficient power supply may damage the display. So, you should use an external power source. You should use a 5V/1A power adaptor with a micro USB cable. Along with your Nextion display, you’ll also receive a USB to 2 pin connector, useful to connect the power adaptor to the display.

The best way to get familiar with a new software and a new device is to make a project example. Here we’re going to create a user interface in the Nextion display to control the Arduino pins, and display data.

We won’t cover step-by-step how to build the GUI in the Nextion display. But we’ll show you how to build the most important parts, so that you can learn how to actually build the user interface. After following the instructions, you should be able to complete the user interface yourself.

Open Nextion Editor and go to File > New to create a new file. Give it a name and save it. Then, a window pops up to chose your Nextion model, as show in the figure below.

We’ll start by adding a background image. To use an image as a background, it should have the exact same dimensions as your Nextion display. We’re using the 2.8” display, so the background image needs to be 240×320 pixels. Check your display dimensions and edit your background image accordingly. As an example, we’re using the following image:

Once the GUI is ready, you need to write the Arduino code so that the Nextion can interact with the Arduino and vice-versa. Writing code to interact with the Nextion display is not straightforward for beginners, but it also isn’t as complicated as it may seem.

A good way to learn how to write code for the Arduino to interact with the Nextion display is to go to the examples folder in the Nextion library folder and explore. You should be able to copy and paste code to make the Arduino do what you want.

In this post we’ve introduced you to the Nextion display. We’ve also created a simple application user interface in the Nextion display to control the Arduino pins. The application built is just an example for you to understand how to interface different components with the Arduino – we hope you’ve found the instructions as well as the example provided useful.

In our opinion, Nextion is a great display that makes the process of creating user interfaces simple and easy. Although the Nextion Editor has some issues and limitations it is a great choice for building interfaces for your electronics projects. We have a project on how to create a Node-RED physical interface with the Nextion display and an ESP8266 to control outputs. Feel free to take a look.

Hi, thanks for the info on the conversion, that was OK, I can convert my large Nex HMI and load in the Chinese version of the USART and that builds a TFT and that loads, all good, so the factory can use that to load the TJC panels. big thumbs up,

comment I have is the (other notes) about converting the USART to english is not much point, as the Device(s) are still NEX anyway, unless there was a mod for that I dont see, so its exactly the same as the Next Editor anyway. so i just leave in Chinese and build a TFT from my import,

Excellent display, very easy to use. The software is very well made, I"ve been able to make the whole guy for my project in under 2 hours which is insane. The display is so nice and so great I am buying nextion lcd"s again for SURE! And the fact that you can plug the screen in to a 5V source and the display work with the gui is insane, and you can easily uploade your program with a micro sd card and thei software. you just upload to the sd card the program you made in the nextion editor. This screen adn the entire bran is very good. 11/10 would recomand, I am buying again!
