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 windows

Text-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.

NX3224F028 VS NX3224T028

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.

Smooth migration from 3.2 enhanced to 2.8 Discovery

I needed to move from a 3.2" enhanced to a 2.8" Discovery display. It's a cost sensitive application, the 2.8" discovery seems widely available and offers a good cost saving as I wasn't using any of the enhanced model features. Some tweaking of graphics layout was required due to the change in display resolution. Code is compatible and performance remained fast an responsive. I'm pleased with the move. (Used on LoadMaster PV hot water project - see Arduino Project hub)
