Nextion Editor Quick Start Guide

Introduction

Nextion Editor(Official Download) is a development software used for visual building of graphic interface for embedded GUI-intensive devices with various types of TFT displays and Touch Panels. Using this tool, users can start creating TFT based devices in a faster and easier way.

In the future, Nextion Editor will provide a series of examples intended to speed up the user’s work and creation process. Examples are fully commented and explained, allowing a quick start in designing user interface. Refer to the available examples to learn how to create GUI application will help users to finish their project with minimum of time and effort.

  • 7. Compiler Output Window: if errors occur, they will be shown in this area.
  • 8. Event Area: Write some simple codes here. When the event is triggered, the codes you write will be run. For example, send out some command to UART when releasing a button component.

Main Menu

File

Users can open/import/save project by clicking File.

Tool

There are two tools: Font Generate & Eyedropper

Font Creator

When user start a project, Font generating is the foremost thing they need to do. Only by taking this step can users input characters in Text component. It supports all your local fonts now. Save the generated font in the zi folder.

Eyedropper Tool

Actually, it is a color decimal converter. When user pick a color in this tool, it will tell them the color’s decimal code. This will be very helpful if they use commands to do GUI editing.

Open, New, Save

These three buttons are for users to open a project, to add a new project, or save a project.

Compile

It is used to refresh a project, but it does not save the project. If users modify some attributes of a certain component, they’ll need to click it so that the modifications can take effect.

Debug

Click it, there will be a simulator pop-up window. Users can test the project they have done or input codes to know whether their project is going right or not.

Upload

This button is for users to upload the project into Nextion TFT Display.

Add Component

So far, there are text, button, progress bar, picture, crop, gauges, hotspot, waveform, slider, timer, variable, number, dual-state button components available. To find out more about these component’s editing guide, please see the following sections.

Delete Component

Users can choose Delete All Components or Delete Selected Components.

Copy, Cut, Paste

Select components and then copy, cut or paste then!

Delete, Undo, Redo

Delete the selected components. Undo: repeat last operation. Redo: cancel last operation.

Setting

Nextion display model.png Nextion display direction.png

Used for changing user device model, project display direction. Please note users should create a project’s resolution according to their Nextion device model.

ID

Click ID to choose whether to show the components’ IDs or not.

Style

Select the Nextion Editor display background style: blue or black.

Components Formatting

Formatting selected components. The icons includes: Bring Top, Bring Bottom, Align Left, Align Right, Align Bottom, Same Width, Same Height, Same Size.

Image Library

User can import the pictures in this panel by clicking Add button. Note that, every picture has its own ID number, so if users insert or delete any images, the ID number will get changed. Users can use the tool to move their image up or down.

Font Library

Font library is very important! If users want to use different font size or patterns in their projects, they’ll need to generate different fonts and add them in the font library panel.

Click here to learn how to generate a font.

For example, using 16 and 40 pounds font size in a project, user will need to generate two fonts, one will be 16 pounds, and the other will be 40 pounds.

In the font library panel, every font has its unique ID number, and so delete any one will change its Font ID number.

Then, what’s the ID number for? When users editing the text attributes, there is a font option. The value users can input is the Font ID number.

Page Area

Users can add, insert, delete, and copy a page by using the bottom buttons. By double-clicking a page, users can define name for a page, and press enter key on computer keyboard to save the changes. Note that, only by pressing enter button of the keyboard can save the defined name.

Display area

Users can drag-and-drop any component in the working area. Nextion editor supports three background patterns: no background, solid color and Image.

Components

So far, there are eleven components available in Nextion editor. We will introduce their features one by one. Note that, only attributes in green color are available to use commands for editting. And those attributes in bold will be refreshed automatically after modification.

For example: We debug t0 with command”t0.txt=”changetxt””, we will see the change immediately. But if we want to change the text color with command”t0.pco=65535″, we can’t see the change immediately, so we have to add a command “ref t0”, then it will work.

  • Nextion Editor is not perfect, it is being improved continually. We welcome any suggestions, so please don’t hesitate to comment in our forum!

Text

Text component is for user to input characters. Click each attribute, its meaning will be shown on the bottom.

In sta attribute, users can choose different background patterns: crop image, solid color and image. Generally, crop image is for creating transparent background.

Button

Compared to text component, Button has a press event attribute, which means users can fill different color or effect for a button when it is being pressed.

Dual-state Button

A dual-state button provides a button that can be switched between two states, for example: ON and OFF, OPEN and Close, Start and Stop.

Note:The statement of variable should be “pageNAME.cmpNAME.val or txt”.

Debug, online simulator

By using debug function for the project, users can examine whether their project will work as expected or not. Users can also use some codes to realize the simulative effects.

When users click debug, there is a pop-up window to show you the simulator interface.

Nextion Guide 30.jpg

In this window, users will see some other panels like User Code and Simulator Output, returned data from Nextion TFT boards.

  • Send command to

Nextion Guide 31.png

There are three options: “send command to serial port”, “send command to serial port”, and “send command to both simulator and serial port”. Do remember that users should click “connected” to connect to the Nextion TFT when they use “send command to serial port” and “send command to both simulator and serial port” options.

  • User code panel

In this panel, users can use the command to debug their project. The commands are listed on our wiki, please click here to view.

  • Simulator Output

When users debug their project, input some commands in User code panel, the Simulator will return some data by responding the executed of commands. The respond data are in binary format, please click here to know what the respond data means.

  • Data returned from serial devices

This panel takes effect when users choose “send command to serial port” or “send command to both simulator and serial port”.

When users do some operation on Nextion TFT boards, this panel will show the respond data in binary format, Please click here to know what the respond data means.

  • Download current resource file to device

After users debug their project, they can click “download current resource file to device”. It’s very convenient. When downloading, choose the Nextion serial COM and keep default bound rate.


Flash Project firmware from SD card

1. Open the bin folder and copy the project firmware in two ways:

1.Open Nextion Editor→File→Build Folder

2. Open the computer path like this: Open Computer→ Local Disk(C:)→ User→User’s Computer(User’s Computer name)→ AppData→ Roaming→ Nextion Editor→ bianyi,you will see the project file in tft format.

Note1: Only this tft format file could work. Copy the tft file to SD card, then insert SD card in the Nextion SD card slot(make sure there is only one tft file in SD card), power up Nextion, and then the project installation will be automatically proceeded.

Note2: Store only one tft file in the SD card, and the resolution of tft file must be in accordance with the resolution of Nextion TFT.

Note3: The SD card should be in FAT32 format and less than 32G.

If users fail to program with SD card, they can view this: http://support.iteadstudio.com/discussions/topics/1000063885

Upload HMI project through serial port

1. Connect Nextion display with a Foca(USB–TTL) as below:

Foca (USB–TTL)— Nextion Display

5V——-5V

GND——GND

TX——-RX

RX——-TX

2.Connect Foca with computer by a USB cable

3.Click “Upload”in Nextion Editor to upload the HMI file to Nextion display
