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.

Advanced programming – the flicker-free gauge

Everything started in a Nextion-related group on Facebook where a young man who is into motor tuning - let's call him "M." - asked for advice: "Hey! I'm building a gauge with the "line" command. Now I'm searching a way, to find all correct X and Y of the outside circle. How can I do that ? I Just need every 3° so i have 120 X and 120 Y numbers. I also looked into the Sunday projects of Thierry Frenkel but I can't get any way to understand, how to get this coords of a circle by itself an put it into a val.txt and read it with spstr. Maybe Thierry can help me with this ? ..."

Professional GUI – Popup windows

Sometimes, showing some information, a warning, or an error message is required in a HMI project. And many paths lead to Rome. What I'll show here today is a kind of custom component or object which can be customized and called from different contexts, similar to the screen keyboards which can be easily added to text and numeric input fields in the editor.

Protocols and parsing – Part 4: Receiving and decoding MIDI messages

Over the last weeks, we learned about the Nextion active protocol parse mode in general, about the MIDI protocol in Detail, and we got a first and simple demo project which taught us how the Nextion HMI could send MIDI messages or commands in standalone mode. Today, things become a little more complex: We want to receive and to decode MIDI messages and commands. For this demo project, we'll implement two functionalities: Soft-through, which means that received, decoded and validated commands are then re-sent, and a MIDI monitor which should show us the MIDI data stream in a human readable form. Afterwards, it might be up to you to to add other functions like GPIO triggers or visual effects, or even filtering, transforming, and re-sending the midi data for additional effects like transposition or adding sub-harmonics (octavider), based on this framework.

The Sunday Blog: Protocols and parsing – Part 3: Sending MIDI messages from Nextion HMI

Two weeks ago, we talked about data protocols and the active protocol parse mode of the Nextion HMI. Last week, we looked deeper into the protocol and data structure of the MIDI protocol which allows to exchange messages between electronic music instruments. You guess it, it can not only be handled in Nextion language, but using a Nextion HMI as a MIDI controller in standalone mode, which means without an external MCU like Arduino etc. has many advantages. Typically, most MIDI controllers (if this aren't keyboards) have a status display or multiple rows of LEDs and many, many knobs and buttons. That isn't forcibly ergonomic, especially when you are live on stage and you want just quickly change a single setting. In such situations, an intuitive GUI and dematerialized knobs, buttons and sliders give simpler usage, less production cost and make the "apparatus" ways more robust.
