Programming and Electronics knowledge are prerequisite
– there are many external internet resources available
– there is no need to replicate all global information here
Nextion can be used with 68000+ MCUs with a Hardware/Software
TTL Serial, in 130+ programming languages.
It is the User Duty to know
– their chosen MCU
– their chosen Programming Language
– their chosen Compiler
The Hobby Lobby is not to be used as a Jobs Board.
– For this, Itead offers Enhanced Support and Project Units
If Enhanced Support is not the path you would like to go
– there are other Freelance sites on the Internet.
Itead’s Iteadlib Arduino Nextion Library is available
via github and can be downloaded from
https://github.com/itead/ITEADLIB_Arduino_Nextion
Default configuration is for the Arduino MEGA 2560
The Arduino UNO is also supported – see readme.md file
This framework can be used to port to another MCU
The latest version of Nextion Editor can be downloaded [here]
The Unit of Screen Brightness is in percentage %
The Range of Screen Brightness is 0 to 100.
– Please refer to dim and dims in the Nextion Instruction Set [here]
For the brightness in nits of your Nextion device
– Please refer to your Nextion model’s Datasheets [here]
The Nextion Editor requires Microsoft .Net 3.5
Download Microsoft .Net 3.5 [here]
Currently, the microSD slot is used to upload a TFT project file only.
– all other potential uses are currently not supported.
Not all microSD cards are made for use with embedded devices.
– especially newer microSD cards made for cameras, etc.
Class 10 HC 8GB to 32GB cards have had good success. Others too.
Ensure
– microSD card formatted as FAT32 under Windows
– microSD card is less than 32 GB
– only 1 TFT project file exists on the microSD card
– Nextion device is powered off before inserting microSD card
– insert the microSD card containing TFT project file
– power on Nextion with recommended clean power as per Datasheets
– Nextion device is undisturbed while uploading
– after upload “successed” indication power off Nextion
– after Nextion device is powered off then remove microSD card
– power on Nextion with recommended clean power as per Datasheets
– if new version of Nextion Editor, allow time for firmware to update
– wait for uploaded project to begin running on Nextion device
If microSD upload is unsuccessful
– Reformat the microSD card – ensuring FAT32 under Windows, and try.
– use a different microSD card (HC, Class 10, under 32GB), and try.
– compile a blank HMI project and try again.
– microSD card is not the only method to upload project – try via USB to TTL.
Using the above steps, the Nextion device will always run firmware upload
when an inserted microSD is detected at power on (power off before insert/remove)
This may be a Power supply problem. Please ensure to power your device according to the datasheet power supply range with the recommended supply of current. Under Voltage can cause damage. Over Voltage will cause damage. Too high or too low voltage is likely to damage back-light. For datasheet please refer to your model’s Datasheets [here]
Standard Support (Level 2) is offered to Itead customers.
– you must deal your Seller as per Buyer-Seller protection laws
– we only ensure the hardware itself works as expected
– please understand that we can not debug your code.
Supported is stated on the Standard Support page.
Enhanced Support is available by purchasing Tickets here
– quick and professional service, but indeed paid
Community Support is available via the Forum here
– community members will voluntarily answer when they desire.
Nextion is a 5V TTL Serial HMI device, be mindful
to ensure connecting to an appropriate adapter
The connection between Nextion and control device
Nextion Display -------- Control Device 5V --------------------------5V GND --------------------------GND TX --------------------------RX RX --------------------------TX
Ensure Ground with all used devices is common.
Control device: FOCA, USB-to-TTL, USB-to-UART, PC, MCU, Arduino
Ensure sufficient current supply as per Datasheets (here)
Please ensure Microsoft .Net 3.5 is installed
Sorry, currently we only have a Windows supported version. If we reach our sales goal in 2016, we will have enough budget to design the cross-platform web UI. Before that, we will focus on one platform. Ensure Microsoft .Net 3.5 is installed for Windows.
Others have used Windows virtual machines under Linux and Mac. Although user operating systems and used software is beyond the scope of Nextion support, it is possible.
No. Nextion is not Open Source. Nextion will not be Open Source.
– we will not provide Nextion schematics, Nextion PCB layout, components used, Nextion Editor source code, or any of the design data involved.
What is available to the public has been made available
– please refer to your Nextion model’s Datasheet [here]
