Source

Source 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

How to get started

On the home page of API documentation, the tabs of Examples, Classes and Modules will be useful for Arduino lovers.

Mainboard Requires

• RAM: not less than 2KBytes
• Serial: one serial (HardwareSerial or SoftwareSerial) at least

Suppported Mainboards

• Arduino UNO and its derivatives
• Arduino MEGA and its derivatives

Using SoftwareSerial

If you want to use SoftwareSerial to communicate with LCD touch screen, you need to modify the line in file hmi.h:

//#define HMI_SOFTWARE_SERIAL

After modification, it should be:

#define HMI_SOFTWARE_SERIAL

Hardware Connection

HMI library only needs an uart for hardware connection. All communications are done via uart. Before using this examples, you should ensure that your LCD touch screen have been connected.
