modified the file NexConfig.h.
This version uses only one Serial to communicate with Nexion display. No debugging serial available
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.

Latest version is unstable and a mass of change may be applied in a short time without any notification for users. Commonly, it is for developers of this library.
Release version is recommanded for you, unless you are one of developers of this library.
Release notes is at https://github.com/itead/ITEADLIB_Arduino_Nextion/blob/master/release_notes.md.
Latest source code(master branch) can be downloaded: https://github.com/itead/ITEADLIB_Arduino_Nextion/archive/master.zip.
You can also clone it via git:
git clone https://github.com/itead/ITEADLIB_Arduino_Nextion
- https://github.com/itead/ITEADLIB_Arduino_Nextion/archive/v0.7.0.zip
- https://github.com/itead/ITEADLIB_Arduino_Nextion/archive/v0.7.0.tar.gz
All releases can be available from: https://github.com/itead/ITEADLIB_Arduino_Nextion/releases.
Offline Documentation's entry doc/Documentation/index.html shiped with source code
can be open in your browser such as Chrome, Firefox or any one you like.
All boards, which has one or more hardware serial, can be supported.
For example:
- Iteaduino MEGA2560
- Iteaduino UNO
- Arduino MEGA2560
- Arduino UNO
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.
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
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
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).
