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 you can start creating TFT based devices much faster and easier.

In the future, Nextion Editor will provide a set of examples intended to speed up your work and creation process. Examples are fully-comented and explained, thus allowing a quick start in designing user interface. Browse through the given examples and learn how to create GUI application with minimum of time and effort.

  • 1: Main Menu
  • 2. Components  
  • 3. Image Library:Import the image resource you need in project. Font Library: Storage the font you created by font editor.
  • 4. Display area
  • 5. Page Area: Edit page in this area  
  • 6. Attributes Editing Area:Edit the attributes of components and pages, such as the value, color of a text component.
  • 7. Compiler Output Window: if errors occur, they will be shown in this area.
  • 8. Event Area: Write some simple code here. When the event is triggered, the code you write will be run,for example, sending out some command to UART when release a button component.

Main Menu

File

You can open/import/save projects by clicking File.

Tool

There are two tools: Font Generate & Eyedropper

Font Creator

Nextion font generator.png

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


Eyedropper Tool

Nextion eyedropper.png

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

Open, New, Save

These three buttons for you open, add a new, or save project.

Compile

It is used for refresh project, not gonna save project. If you modify some attributes of a certain component, you need to click it so that your modifications can take effect.

Debug

Click it, there will be a simulator pop-up window. You can test the project you've done or input codes to know whether your project is going right or not.

Nextion Guide 5.png

Download

This button is for you downloading the project into Nextion TFT board.

Add Component

So far, there are text, button, progress bar, picture, crop, gauges, hotspot, waveform, slider, timer, variable components available. More about these components editing guide, please see the following sections.

Delete Component

You can choose Delete All Components or Delete Selected Components.

Copy, Cut, Paste

Only used for copy, cut or paste any component!

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 your device model, project display direction. Please note you should create a project's resolution according to your Nextion device model.

ID

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

Style

Select your Nextion Editor display style: blue or black.

Components Formating

Nextion component formating.png

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

Image Library

You can import the pictures in this panel by clicking Add button. Note that, every picture has its own ID number, if you insert or delete any image, the ID number will change. You can use the tool to move your image up or down.

Font Library

Font library is very important! If you want to use different font size or patterns in your projects, you need to generate different fonts and add them in the font library panel.

(So far, font pattern only supports Arial)

Click here to know how to generate a font.

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

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

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

Page Area

You can add, insert, delete, and copy a page by using the bottom buttons. Double-click a page, you can define a name for a page, press enter key to save the change. Note that, only press enter key can save your defined name for a page.

Display area

You can drag-and-drop any component in the working area. Support 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 to edit.And the one in bold is the main attribute that is refreshed automatically

For example: We debug t0 with command"t0.txt="changetxt"", we will see the change at once, but if we want to change the text color with command"t0.pco=65535", we can't see the change, so we have to add a command "ref t0", then it works.

  • Nextion Editor is not perfect, is improving now. We are welcome any suggestions, don't hesitate to judge us in our forum!

Text

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

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

Debug, online simulator

Using debug function for your project, you can examine whether your project is working well or not. You also can use some codes to realize the simulative effects.

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

Nextion Guide 30.jpg

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

  • Send command to

Nextion Guide 31.png

There are three options for you: "send command to serial port", "send command to serial port", and "send command to both simulator and serial port". Do remember that you should click "connected" to connect the Nextion TFT when you use "send command to serial port" and send command to both simulator and serial port" options.

  • User code panel

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

  • Simulator Output

When you debug your project, input some commands in User code panel, the Simulator will return some data to respond the execution of commands. The respond data are in binary format, please click here to know what the respond data mean.

  • Data returned from serial devices

This panel take effect when you choose "send command to serial port" or "send command to both simulator and serial port".

When you 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 mean.

  • Download current resource file to device

After you debug your project, you can click "download current resource file to device", it's very convenient. When download, choose your Nextion serial COM, and keep the default boundrate.


Download Source file from SD card

Open the bin folder 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 to the Nextion SD card slot(make sure there is only one tft file in SD card),power up Nextion, 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 accord with the resolution of your Nextion TFT.

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

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