Overview
Nextion is a Human Machine Interface （HMI） solution combining an onboard processor and memory touch display with Nextion Editor software for HMI GUI project development. Using the NEXTION Editor software, you can quickly develop the HMI GUI by drag-and-drop components (graphics, text, button, slider etc.) and ASCII text based instructions for coding how components interact at display side. Nextion HMI display connects to peripheral MCU via TTL Serial (5V, TX, RX ,GND) to provide event notifications that peripheral MCU can act on, the peripheral MCU can easily update progress and status back to Nextion display utilizing simple ASCII text based instructions.
The Intelligent Series products have more powerful hardware in terms of MCU, Flash storage and SRAM compared with Basic Series and Enhanced Series. What’s more and new? The audio, video and animation play functions enriches user’s project HMI interaction. The Intelligent Series supports advanced software features and functions such as transparent component, page loading effect, component Move and Drag .etc.
You can develop the HMI GUI project via the free latest Nextion Editor software ver 0.58 or above, the easy Drag-and-Drop components and simple ASCII text based instructions will dramatically reduce your HMI project development workloads.
