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 at 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 product 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 Sunday blog: Boost your HMI with advanced mathematics! – Part 1: Introduction

Developers of Nextion HMI solutions often wish to be able to perform display only calculations directly in Nextion code. Be it to relieve the external microcontroller or in a stand-alone application - there is always a reason! A motive could also be that the integrated processor (32bit ARM Cortex M0+ or better) in the Nextion HMI is significantly more powerful than many of the 8bit AVR or PiC processors used in the hobby and control sector.Before we learn what hidden horsepower our Nextion HMI has under the hood and how to use it optimally, let us first recall some basics. Because only if we understand in principle how a microprocessor calculates can we make the best use of its capabilities.

The Sunday blog: HMI, cybernetics and the steam engine – Part 7: Didactic code

Today is the day! Our project comes to an end! After we built a nifty GUI for our dishwasher HMI in the last episode and we set up a sophisticated system to transfer all the status information from the controller to the HMI within a single packed 30bit number (see Part 5), we'll now write the code to animate our GUI. The title of this episode is "didactic code". That means, it comprises elements (like the "door open" flag of our dishwasher) which we don't actually use in our GUI. It's also written in a way which demonstrates the powerful opportunities of indirect component addressing, which adds a line of code here and there.

The Sunday blog: HMI, cybernetics and the steam engine – Part 6: Professional graphics

In the last episode we have dealt extensively with the Nextion HMI code. With it we already succeeded in "unpacking" the 30bit status message of our virtual dishwasher and saving all details in separate variables. For testing purposes, we then wrote some sample data in text and number fields, but the result was still visually unsatisfactory. That's why we want to work on the graphical frontend today and learn how to do it efficiently!

The Sunday blog: HMI, cybernetics and the steam engine – Part 5: Well thought-out and efficient HMI code

In the last episode of this series, we considered how we could transfer the status information of our virtual dishwasher to the HMI as efficiently as possible without placing unnecessary load on the MCU. We saw that we put everything into a 30-bit bit field, so that sending a single 32-bit integer number is sufficient. Today we want to see how we use Nextion code to unpack and display the information.

The Sunday blog: HMI, cybernetics and the steam engine – Part 3: Embedded development in detail

And here we are again. In episode 1 (link) and episode 2 (link) we followed the rapid technical development and saw how simple tools became machines that could do physical work for humans, and how a new generation of machines emerged that could also do intellectual work for humans, the computers. The latter allows, provided the appropriate programming is in place, to control even very complex machines and to process the status of the machine from a large number of sensors and other measured values and to display them clearly and graphically on a screen.
