Nextion


Introduction

Nextion Arduino library provides an easy-to-use way to manipulate Nextion serial displays. Users can use the libarry freely, either in commerical projects or open-source prjects, without any additional condiitons.

For more information about the Nextion display project, please visit the wiki。 The wiki provdies all the necessary technical documnets, quick start guide, tutorials, demos, as well as some useful resources.

To get your Nextion display, please visit iMall.

Documentation

Documentation includes Configuration, Get Started and Reference of Core API , etc.

Online documentation: http://docs.iteadstudio.com/ITEADLIB_Arduino_Nextion/index.html.

Offline documentation: doc/UserManual/index.html can be open in your browser.(For example, Chrome or the fucking one you like). ​

Source

Latest source code can be download at https://github.com/itead/ITEADLIB_Arduino_Nextion.

You can clone it by:

git clone https://github.com/itead/ITEADLIB_Arduino_Nextion

Suppported Mainboards

All boards, which has one or more hardware serial, can be supported.

For example:

  • Iteaduino MEGA2560
  • Iteaduino UNO
  • Arduino MEGA2560
  • Arduino UNO

Configuration

In configuration file NexConfig.h, you can find two macros below:

  • dbSerial: Debug Serial (baudrate:9600), needed by beginners for debug your nextion applications or sketches. If your complete your work, it will be a wise choice to disable Debug Serial.
  • nexSerial: Nextion Serial, the bridge of Nextion and your mainboard.

Note: the default configuration is for MEGA2560.

Redirect dbSerial and nexSerial

If you want to change the default serial to debug or communicate with Nextion , you need to modify the line in configuration file:

#define dbSerial Serial    ---> #define dbSerial Serialxxx
#define nexSerial Serial2  ---> #define nexSeria Serialxxx

Disable Debug Serial

If you want to disable the debug information,you need to modify the line in configuration file:

#define DEBUG_SERIAL_ENABLE ---> //#define DEBUG_SERIAL_ENABLE

UNO-like Mainboards

If your board has only one hardware serial, such as UNO, you should disable dbSerial and redirect nexSerial to Serial(Refer to section:Serial configuration).
