Nextion is a Human Machine Interface (HMI) solution that combines an onboard processor and touch memory display with Nextion Editor software for HMI GUI project development. Using the NEXTION Editor software, it is possible to quickly develop the HMI GUI with drag and drop components (graphics, text, buttons, sliders, etc.) and ASCII text-based instructions to code how components interact on the screen side. Nextion HMI display is connected to peripheral MCU via TTL Serial (5V, TX, RX, GND) to provide event notifications that peripheral MCU can handle, peripheral MCU can easily update progress and return status to Nextion display using simple ASCII text-based. Compared to Basic Series, Discovery Series has better MCU performance, same functions as Basic and lower price.

In deep sleep mode, the wake-up time will be longer, the data will probably be lost when the serial port receives the wake-up command. Therefore, it is recommended to send a void command and delay 50ms before executing it.
