Nextion Editor Overview

Nextion Editor is a free human-machine interface (HMI) GUI development software for Nextion Basic Series, Enhanced Series, and Intelligent Series. The software offers an easy way to create an intuitive and superb touch user interface even for beginners. Add a static picture as a 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 and develop projects rapidly in a cost-effective way. The Nextion product is the best balance HMI solution between cost and benefit with a low and decreased learning curve.Nextion Editor Features Versatile Character Encoding With several character encoding, you are able to create the HMI project in your language characters and strings. Fonts and Text Styling The font creator allows you to generate the specific fonts applied in each component value or text attribute. e.g.Generate the font of “Arial” with Height “24” and Encoding “UTF-8”25+Amazing WYSIWYG Components Easy-to-use components to customized GUI at screen side allow you to develop projects rapidly in a cost-effective way Component Attribute Setting The component attribute setting gives you the options to design all the aspects of the component that you need.Free Simulator Debug Debug the HMI project at any time even without the Nextion Display.The instruction input area allows you to send any Nextion commands to check the feedback and interactions. Nextion Operational Commands The operational commands allow users to program the HMI interactions by coding in Events windowsText-based Instruction Set Simple ASCll text based instructions will dramatically reduce your HMI project development workloads Support Simple Assignment Operators To handle the calculation and assignment for the text and Numeric data, the simple assignment operators help.

Extremely Low Power Comsuption in Deep Sleep Mode

When the Deep Sleep Mode is activated, the device’s working current is down to 0.25 mA. Your Battery-Powered HMI device will last a longer working time with such a low power consumption.  

15+ WYSIWYG Components for HMI Development

Easy-to-use components to customized GUI at screen side allow you to develop projects rapidly in a cost-effective way Compared with Basic Series, the Discovery Series has a better MCU performance, with the new image compression technique, the Discovery Series allows more pictures in the same amount of flash compared to Basic and Enhanced models. The operating current of deep sleep mode is as low as 0.25mA which makes the Discovery Series displays more suitable for battery-powered projects. 1. Text 2. Scrolling text 3. Number 4. xfloat 5.

Free Simulator Debug

Debug the HMI project at any time even without the Nextion Display. The instruction input area allows you to send any Nextion commands to check the feedback and interactions.

Fonts and Text Styling

The font creator allows you to generate the specific fonts applied in each component value or text attribute. e.g. Generate the font of “Arial” with Height “24” and Encoding “UTF-8”

New image compression technique to Save More Space Usage

Image compression is achieved breaking the traditional 2 byte per pixel formula and allowing more pictures in the same amount of flash compared to Basic and Enhanced models.For example: Add 319 images in NX4832F035 only takes 3.06MB, save up to 70% flash space.

UTF-8 Subset Reduce Font Space Usage

The Font Generator can generate a ZI Font using user-selected combinations of UTF-8 subsets. There are 142 subsets covered all language characters so you can create the HMI project with any language content text.
