What’s Nextion

Nextion is a Human Machine Interface (HMI) solution combining an onboard processor and memory touch display with Nextion Editor software for HMI GUI project development.

Using the Nextion Editor software, you can quickly develop the HMI GUI by drag-and-drop components (graphics, text, button, slider, etc.) and ASCII text-based instructions for coding how components interact on the display side.

Nextion HMI display connects to peripheral MCU via TTL Serial (5V, TX, RX, GND) to provide event notifications that peripheral MCU can act on, the peripheral MCU can easily update progress, and status back to Nextion display utilizing simple ASCII text-based instructions.

Our mission is to reduce the HMI development workloads.


Nextion Offers an Ease of Use and Cost-effective HMI Solution for You.


5 Years LTA

Nextion guarantees the availability of all Series products for a minimum of 5 years with CE and RoHS certification compliant. Unless you are specifically notified at the time of purchase, all Nextion series products purchased will be available at least 5 years since 2019. Here is our LTA announcement.


Versatile Screen Sizes

Nextion is available in various TFT LCD touchscreen sizes including 2.4”, 2.8”, 3.2”, 3.5”, 4.3”, 5.0”, 7.0”, 10.1” . With a large selection to choose from, one will likely fit your needs. Go Nextion Series and Product Datasheets.


Quick and Easy GUI

The Nextion Editor software offers an easy way to create the intuitive and superb touch user interface even for beginners. Add a static picture as background, define functions by components, you can make a simple GUI in minutes. The easy Drag-and-Drop components and simple ASCII text based instructions will dramatically reduce your HMI project development workloads.


Cost-effective HMI Solution

Easy-to-use components, touch event programming and customized GUI at screen side allow you to develop projects rapidly in cost-effective way. The TTL serial Nextion display is the best balance HMI solution between cost and benefit with low and decreased learning curve. See Nextion Editor Guide and Instruction Set.

The program.s file – for what is it good and for what not?

Introduced with the Nextion Editor v 1.60.0 in early 2020 as a container for startup code, the program.s file allowed for the very first time to execute code before the startup page (which was always page 0) was loaded. Although we have been using it many times in our demo projects, and since every project compiled using Nextion Editor v 1.60.0 or newer makes use of it, even when you do not touch at it, I think that it's time to have a deeper look to get most out of it.

Professional HMI project design – Last step: Add the GUI, a few details, and ready!

This is the third and last part of this article series where we wanted to have a deeper look on how to develop a Nextion project systematically, efficiently, and at a professional level. After we talked about gaming mathematics and win plans in the first part, and about animation and timing in the second part where I showed you already a raw proof of concept, it's now time to add a nice GUI and the credits handling, and to adapt and to assemble all the code snippets elaborated during the previous articles, and then, we'll be done!

Professional HMI project design – explained in all steps

In the beginning, there is always an idea for a new project. The worst you can do at this very moment is to launch the Nextion editor and, if needed, the Arduino IDE, and start immediately coding... Before you do the first step, you have to know exactly where you want to go, says an old proverb. In this blog and the following over the next weeks, we'll look at how to define this "exactly where you want to go". The proceeding is quite similar to what you can see in cooking shows at the TV: They first think about what they'll cook, then they make sure that they have all required ingredients at hands, prepare and pre-process them, the famous "mise en place" before everything is added consecutively in an optimal order to the pot or pan, on the stove or in the oven, which is called the "assemblage"...

Nextion Software FAQ

Since many questions are frequently asked - in the Nextion forums, in Nextion user groups on social media, and sometimes directly per email or PM, I decided to compile some of them in this Sunday Blog article.
