NEXTION is a Human Machine Interface（HMI）solution combining a TFT touch display with an onboard processor and memory, develop using the free and downloadable NEXTION Editor software.
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. With just 2 wires (RX,TX), NEXTION display quickly connects to MCU via 5V TTL Serial to provide event notifications that MCU can act on, and utilizes simple ASCII text based instructions so the MCU can easily provide progress and status updates back to your HMI user.
