# Nextion Library for Arduino 

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。](http://wiki.iteadstudio.com/Nextion_HMI_Solution)  
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.](http://imall.itead.cc/display/nextion.html)

# Suppported Mainboards:

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

For example:

  - Iteaduino MEGA2560
  - Iteaduino UNO
  - Arduino MEGA2560
  - Arduino UNO

# Serial configuration

In configuration file `NexSerialConfig.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 file `NexSerialConfig.h`:

    #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 file 
`NexSerialConfig.h`:

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

# UNO

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`).
