Nextion is a cost effective HMI Display which has a TFT Touchscreen and can be easily controlled via Serial Port. Using Nextion Editor you can design an interface on your PC you can easily make text boxes, buttons, sliders, guages, progress bars etc without much hassle.
And most importantly the serial (UART) interface allows you to easily integrate this display to various Micro-controllers, Arduino and even Raspberry Pi. This display is so easy to use that you can even use it with the basic 8051 Microcontrollers.
Nextion is a Seamless Human Machine Interface (HMI) solution from Itead that provides a control and visualisation interface between a human and a process, machine, application or appliance.
This solution includes hardware part - a series of TFT boards and software part - Nextion editor. Nextion TFT board uses only one serial port to do communicating. Let you get rid of the wiring trouble. We notice that most engineers spend much time in application development but get unpleasant results. In this situation, Nextion editor has mass components such as button, text, progress bar, slider, instrument panel etc. to enrich your interface design. And the drag-and-drop function ensures that you spend less time in programming, which will reduce your 99% development workloads. With the help of this WYSIWYG editor, GUI designing is a piece of cake.
Now you can Develop your complete HMI in couple of hours using Nextion Displays.
TYPES OF NEXTION DISPLAYS
