Oh, I used the 3.5" enhanced Nextion in a project last week. I bought it instead of the standard one because I thought I may need the EEPROM. In the end I didn't, but the price difference was small so not much wasted money. Thank you for your youtube videos on the Nextion as they did help me get it going faster. :)
nice to found you Swiss guy, i like your videos, i just start with my first project Nextion display, and i found your content really nice. I'm also from Switzerland from kanton Aargau...
Got my hands dirty so to speak with a Nextion yesterday. Really need a decent interface for my Roboclock and although I finally got my LCD graphics and touch library going perfectly a GUI from scratch is quite daunting and TBO, eats a lot of resources that were really meant for the project itself. The nextion editor although a bit rough can get the job done and I managed (finally) to get the debug simulator to talk to my MCU so I can evaluate it and put some proper tests together before committing to the hardware. I totally skipped their library and after a day I have my own that's now working smoothly and allows me to send variables too and from the Nextion.
@@AndreasSpiess I have made some very pleasing progress now and have a panel for several devices. Even if not used in a project directly I feel it would be a big advantage to allow for one to be connected as diagnostic commands can be sent easily and results sent back. As one example I have a page for a BME280 with T, H and P and a field that has Pin name, ID and Version number. When I go into the page or click on the refresh button it requests the data. I also have a similar one for a GPS module and light sensor. If the MCU does not recognize the request for a certain device then basically nothing happens.
Yeah, I read that at very least 40% of all American presidents are known to be lefties. Current presidential race was doomed to be hopeless because no lefties to choose from! ;) Andreas, don't you think it's time for electing a lefty engineer who knows how to design, fix and run all sorts of "machines"?
Project idea: Wall calendar. The RTC screams for this. With the expansion, it can beep to notice you. Maybe it is too complex, but it would be awesome to read data from your MS Outlook calendar and show the informations from it in your desktop. Good videos, +1 sub on that LED display :)
If you look instrustion set at www.itead.cc/wiki/Nextion_Instruction_Set all command set given e.g. dim=50 (to set brightness 50%) from arduino with nextion library i used command myNextion.sendCommand("dim=50"); //tested by me like wise for rtc setting commands are rtc0, year; rtc1, month; rtc2, day; rtc3, hour; rtc4, min; rtc5, second;
You can set the RTC clock in the Debug section of Nextion Editor. The dropdown menu 'Operations' will show Nextion Device RTC Calibration. Make sure to select 'Nextion Device' in the 'Send command to:' menu. The display has to be connected. Hope that helps
Easy way is to remove and reinsert the battery to reset the clock then stay awake until late in the night . At midnight sharp power on the display so the clock will start as 00:00:00. If you do a mistake correct next day :-)
thanks mike for the help, i created two buttons one for increment and one for decrements, like for time rtc3=rtc3+1 //increments the hour by one rtc3=rtc3-1 //decrements the hour by one rtc4=rtc4+1 //decrements the minute by one rtc4=rtc4-1 //increment the minute by one rtc5=rtc5+1 //decrements the seconds by one rtc5=rtc5-1 //increment the seconds by one likewise you can do for Date as well!!!
Nice review - but given the cost/functionality, I would say $90USD is too much. I would say it would be useful for under $30. Perhaps in time, the cost will drop ... But for that price I'd get a tablet with Bluetooth for communication and self powering.
The cost of 7" touch displays are quite high (40-50$ for HDMI types). But they cannot easily be connected with an MCU smaller than the "Raspby Class". And there, the driver chips are on the Raspby board and you pay it there. So, in my view, the Nextion is a valid alternative, not better or worse, just different...
What about an android tablet, there is a large choice at less than $50. You have usb and wifi interface, plenty of ram rom and extra processing power. In a non-proprietary end well supported environement.
John Kubik , the Nextion is different in its application. It boots instantly and you program it easily to work only with your micro, no android overhead. Not the cheapest, but has a niche.
you just added components to the project, bluetooth , while this requires two wires RX, TX, and i'd love a self powering tablet where do you get those? lol
Hi Andreas ! Do you have any Information about the power comsumption of these nextion displays. I'd like to build a solution to control various devices on a boat where electric power is always limited by the capacity of the batteries. Do the displays have a power-save mode like a screensaver on a pc ?
They are quite power hungry. Maybe you find the info in the datasheet. It depends on the size of the display. I do not know of a power save mode. But maybe you switch it completely off by the CPU (using a MOSFET)?
Thanks! I have many sensors lying around and waiting for a presentation. What would be your special interest in temperature sensors? What should I compare?
Maybe I will be faster with the MAX7219 display ;-) Thanks for the tip with dweet.io. I have to look at that, too... BTW. Do you know how to write your own IFTT recipe/ interface? So far, I only saw preconfigured bricks which can be configured.
Not easy for me as I do not have a calibrated thermometer. So, I could only use the "Swiss democratic approach" where the majority is always right. Maybe for the future...
Hello Andreas, I must say I like you projects,in regards to this enhanced new nextion version; I am verry new to this. Do you think it is possible to use and control the I/O without MCU, for example have a code running, Nextion language, control PWM outputs and etc. without the need of a micro-controller attached
I have 3.2" standard Nextion, I just gather there isn't enough information. I tried to play and getting to hang on it, some I do need learn a little more, maybe if there a teaching a small thing to show off, just an idea. At the moment it still sitting in a box and waiting.
Hi Andreas, I bought one of these displays after seeing them on your videos. Unfortunately i made a mistake and it has gone over voltage. I'm desperately trying to find out the values of the component around and including U4 as it is badly damaged. You would be a massive hero if i could know the components or a high res image of that area.
Hi Andreas I have some Sonoff and i want to know if it is possible to connected directly to Nextion (the smaller one 2.4") because i want to used like switch (if the 5 v produces by sonoff pin gonna ok for the Nextion) Thanks a lot you do a great job
I did not look closely to the Sonoff so far, but if you have the RX an TX exposed, and if it has a strong enough 5 volt rail, it should be possible. But the Nextion and the programing will use the same leads. Just keep in mind: the Sonoff has 240 volt inside the box and you decide whether it is a good idea to do that.
Do you know where to find the programs that come with the displays? As soon as I powered mine up, it had a nice example pre-loaded and I'd like to modify it
Do you know if a dht11 sensor could be connected to this screen and by having digital inputs and outputs read directly the humidity and temperature values, without having to use any arduino or any other element, any example?
Hallo Andreas, vielen Dank für das Video.... Ich habe da noch eine andere Frage... gibt es keine Möglichkeit bei Aliexpress die "Wishlist" in den Warenkorb zu laden... ich habe da 100 Artikel drin ;-)
Ich verwende die Wishlist nie, ich lege die Waren immer in den Einkaufskorb. Dann bestell ich mobil. Da kann ich ankreuzen, welche Artikel ich (noch nicht will). Ausserdem gibt es immer wieder mobile Aktionen... P.S. Das gibt aber eine grosse Rechnung. Vorgezogene Weihnachten?
Hmm ok, dann muss ich wohl eine Stunde klicken ;-) "Das gibt aber eine grosse Rechnung. Vorgezogene Weihnachten?" Lach, nein ich möchte einen kleinen Elektronik-Arduino-Bastel-Shop machen...
Andreas Spiess apropos Aliexpress. Mich hat bisher immer davon abgehalten dort zu kaufen, dass man nur per Kreditkarte zahlen kann. Ich mag aber den Chinesen meine KK Daten nicht geben. Gibt's da Neuigkeiten? Paypal oder so?
Michael Bernhardt Du musst nur deiner Kreditkartenfirma trauen. Die halfen mir jeweils. Wobei ich bei Aliexpress noch nie Probleme hatte. Und das bei 1000 Paketen über die letzten Jahre.
I agree, but as soon as "battery" is mentioned these days the freight companies think "dangerous lithium' so it's just easier for the sellers to not put it in.
I recently bought 2 10,000uf capacitors from China, when I got them after 2 months in transit, they still had a charge and caused sparking. I think they should not mention batteries at all.
Hi, Andreas, is it possible to use this Nextion UART Display as simple text monitor for debuging info from esp8266 (Serial.println function) ? Just as text with scrolling ?
DEAR Andreas , Good morning . I am new . Sorry for my ignorance . I have an Arduino UNO R3 . Can I use a nextion display ? Thank you very much . walter
Hallo Andreas, Ich bin begeistert von Deinem Wissen, und wünsche dir weiterhin viel Erfolg! Meine Frage basiert darauf Nextion-Editor auch auf anderen tft-Displays nutzen zu können. Ausgangssituation: ich habe mir vor 2 Wochen nen Arduino kit mit einem due einem tft-Shield und einem 7"-Display besorgt. Dabei habe ich gemerkt das dass Display vom due ca. 54 Pins hat (Nextion display 4). Dessweiterem habe ich gemerkt das dass Display vom due auch einen Sd-Karteneingang hat. Zur meiner frage: Wenn ich 2 Serielle Pins vom due mit 2 Seriellen des Displays verbinde (der due hat viele), wäre dann die Kommunikation beider komponennten somit hergestellt?? Und würde das Programm vom Nextion Editor überhaupt auf dem display von due laufen ?? Probieren konnte ich noch nicht da es noch auf dem weg zu mir ist :/ Mit freundlichen Grüßen
Vielen Dank für dein Kompliment. Du hast dir hier ein Projekt angelacht, das nicht einfach ist. Anhand deiner Fragen vermute ich, dass du dich mit Mikroprozessoren noch nicht so gut auskennst. Deshalb würde ich dir empfehlen, nicht gerade mit dem (teuren) Nextion zu beginnen. Wenn du die Technik soweit beherrscht, kannst du meine frühern Nextion Videos (in einer Playlist) anschauen. Dort erkläre ich, wie es geht. Wenn du noch nicht alles verstehst einfach weiter üben... Zu deinen Fragen: 1. Ja, die Verbindung wäre hergestellt und vielleicht auch die Kommunikation.Das hängt aber von verschieden andern Faktoren ab 2. Das Nextion wird selbst programmiert und muss mit dem Programm, das du auf dem Arduino programmierst, exakt zusammenarbeiten. Das ist schwierig und klappt nicht immer. Ich habe auch lange geübt und deshalb diese Videos gemacht, damit es andere einfacher haben. Viel Erfolg!
Ich habe noch eine Frage übersehen: Die Nextion Displays haben einen eigenen Prozessor (deswegen sind sie so teuer). Alle andern Displays haben das nicht, sie sind also nicht kompatibel.
+Andreas Spiess Danke für die prompte Antwort! Es ist mir natürlich eine Ehre auch diese Videos anzuschauen, da ich es ohne die warscheinlich nicht hinkriege :D "...SSD1963 Controller On board 64Mbit SPI Flash..." diese Aussage über das Display vom Hersteller sagt wohl aus, dass es einen Mikroprozessor hat welches schonmal top ist. Sie haben richtig angenommen. Ich fange quasi von null an. Mithilfe Ihrer Videos klappt das. Kurzer Einblick in mein Vorhaben: ich möchte ein gut aussehendes Digidales tachoinstrument für meinen 45er Roller entwerfen, welches neben der Km/h und Tankanzeige (wie beim Originalen Tacho) auch Faktoren wie z.B. Temperatur und Drehzahl anzeigt. MfG
Leider ist der SSD1963 kein programmierbarer prozessor, sonder nur ein Embedded Display SRAM LCD Display Controller. Hier findest du vielleicht etwas: th-cam.com/video/zo33X3VIs2I/w-d-xo.html Das hat mit Nextion nichts zu tun
By default like many other serial ports it is set to 9600 baud. But the Nextion supports up to 115200. Remember that you have have to set this speed at both the microcontroller and the display for it to work properly. I use the Nextion display (also enhanced version, the more powerful processor and more memory are a good trade for a little higher price than the basic model) with several micro controller (Atmel Tiny and Mega controllers). As long you have an uart (serial connection) available, you're good to go. Using the Nextion editor you can design all the screens. Commands like 'page 1' can also be send from the controller. It's not that difficult to communicate from the controller with the display. The Nextion editor also has a debug option. The only thing you're controller has to do, is sending the exact same commands (statements) to the display. I only use the 'low-level' instruction set and not any Nextion wrappers. If you're able to program a PIC controller, than this instruction set should pose no issues for you. Remember that you're controller is not responsible for rendering the display. It does mean you're application is a bit fragmented. The UI part is done with the Nextion editor and the compiled code (firmware) is uploaded to the nextion by SD card. The controller code is in my case written in C++ using Atmel Studio (free Visual Studio based IDE) and uploaded to the controller via avrdude.. Note that this display does NOT have an HDMI connection which is the main reason why even a simply entry PIC controller can drive the application behind the user interface. RTC can be set by sending the 6 date/time components (year, month, day, hour (24h), minute and second as rtc0, rtc1, etc. To set the current date/time: (don't forget the tripple 0xff code to 'execute' the statement) rtc0=2017 rtc1=12 rtc2=18 rtc3=0 rtc4=10 rtc5=38 Reading a RTC date component can be done using "t1.txt=rtc0" to write the current year to a textbox. The only thing I write to the display EEPROM is my application version. If the EEPROM version is not available or older than the current application version, it will start the app-init part and the user can enter the current date/time and some other settings. I hope that in a future update, it is possible to flash the display firmware using the UART interface which would make it easier to keep the controller and display code in sync..
Out of the box one would expect to see an example for a menu type to use with that gpio module. It will also only be useful for high/low type io, no digital sensor comms or analog reading, thus no direct sensors can be connected with the current libraries - really very limited... This really limits the usefulness of the gpio functionality itead tries to add, and combined with poor documentation and old libraries, I am afraid this product will be a bit of a disappointment - waiting 5 weeks for delivery down in South Africa already :(
They are quite creative. I like the new Sonoff and also the extremely small 8285 board. Their problem is just the software side. I hope, they can fix it. I think, a guy who has the specifications can adapt the existing library in a few hours and write a decent example app in a few days. Shouldn't be impossible...
Hallo Herr Spiess, Haben Sie das Display noch? Mir ist ein IC auf der Platine abgebrannt und ich kann nicht ablesen was da drauf stand. Der Support will nicht helfen und sagt nicht um was es sich handelt. Könnten Sie mir dabei helfen? Es handelt sich um das Bauteil "U4" und befindet sich in der Nähe des weißen Steckers und hat 6 Pins. Ich konnte nur was mit "6HD" ablesen, aber ich finde nichts darüber. Eventuell sind Sie in der Lage mir zu helfen. DAnke! LG Robert
Bei meinem 7" Enhanced steht IL 6EP drauf. Es müsste eigentlich ein Switching Converter sein. Allerdings habe ich auf die Schnelle keinen gefundengefunden.
You was tapping on the screen to "change time" as the display was asking to "enter password".. Password is 1234 (see it at the bottom of the screen) good display tho

Hiii Andreas,
Nice videos from you.To set clock u need to go nextion editor>>>Debug>>>operation>>>Nextion device rtc calibration.
And then, use which commands? Do you also have an example code of accessing the RTC or the EEPRPM/GPIO from a microcontroller?
If you look instrustion set at www.itead.cc/wiki/Nextion_Instruction_Set all command set given
e.g.
dim=50 (to set brightness 50%)
from arduino with nextion library i used command myNextion.sendCommand("dim=50"); //tested by me
like wise
for rtc setting commands are
rtc0, year;
rtc1, month;
rtc2, day;
rtc3, hour;
rtc4, min;
rtc5, second;
Thanks. I'll try it out.
Thank you for the video. I am might going to use the display for my egg incubator.
Sounds like an interesting interesting project.

Hi Andreas,
Your videos are really informative, any update about setting up time in the RTC clock? I have bought extended one.
No. But I did not check. I have to do it in the next weeks...
You can set the RTC clock in the Debug section of Nextion Editor. The dropdown menu 'Operations' will show Nextion Device RTC Calibration. Make sure to select 'Nextion Device' in the 'Send command to:' menu. The display has to be connected. Hope that helps

Can you use the io's of the display for sensors? Like remperature sensor? Or a sonar to turn the display on when you come close?
You always have to have this functionality in a microprocessor. The display is not very intelligent...

I noticed you were pressing on those displays - aren't the new ones capacitive?
Mine are still resistive. I think, they did not change the display, just the controllers (in the bigger models)
could you please send me backup file of this HMI
it's look attractive
Are all Nextion TFT Touch displays are resistive touch screen ?
I am not as specialist in this, so I do not know
Hello. Is the HDMI display compatible with 8 bit PIC microcontrollers?
It uses 9600 serial connection. So, if you controller can do this, it should be ok. But you have to write your own code/library, I think
By default like many other serial ports it is set to 9600 baud. But the Nextion supports up to 115200. Remember that you have have to set this speed at both the microcontroller and the display for it to work properly.
I use the Nextion display (also enhanced version, the more powerful processor and more memory are a good trade for a little higher price than the basic model) with several micro controller (Atmel Tiny and Mega controllers). As long you have an uart (serial connection) available, you're good to go.
Using the Nextion editor you can design all the screens. Commands like 'page 1' can also be send from the controller. It's not that difficult to communicate from the controller with the display. The Nextion editor also has a debug option. The only thing you're controller has to do, is sending the exact same commands (statements) to the display. I only use the 'low-level' instruction set and not any Nextion wrappers. If you're able to program a PIC controller, than this instruction set should pose no issues for you.
Remember that you're controller is not responsible for rendering the display. It does mean you're application is a bit fragmented. The UI part is done with the Nextion editor and the compiled code (firmware) is uploaded to the nextion by SD card. The controller code is in my case written in C++ using Atmel Studio (free Visual Studio based IDE) and uploaded to the controller via avrdude..
Note that this display does NOT have an HDMI connection which is the main reason why even a simply entry PIC controller can drive the application behind the user interface.
RTC can be set by sending the 6 date/time components (year, month, day, hour (24h), minute and second as rtc0, rtc1, etc.
To set the current date/time: (don't forget the tripple 0xff code to 'execute' the statement)
rtc0=2017
rtc1=12
rtc2=18
rtc3=0
rtc4=10
rtc5=38
Reading a RTC date component can be done using "t1.txt=rtc0" to write the current year to a textbox.
The only thing I write to the display EEPROM is my application version. If the EEPROM version is not available or older than the current application version, it will start the app-init part and the user can enter the current date/time and some other settings.
I hope that in a future update, it is possible to flash the display firmware using the UART interface which would make it easier to keep the controller and display code in sync..
Andreas du bisch der hammer!
Danke!
Out of the box one would expect to see an example for a menu type to use with that gpio module. It will also only be useful for high/low type io, no digital sensor comms or analog reading, thus no direct sensors can be connected with the current libraries - really very limited... This really limits the usefulness of the gpio functionality itead tries to add, and combined with poor documentation and old libraries, I am afraid this product will be a bit of a disappointment - waiting 5 weeks for delivery down in South Africa already :(
They are quite creative. I like the new Sonoff and also the extremely small 8285 board. Their problem is just the software side. I hope, they can fix it. I think, a guy who has the specifications can adapt the existing library in a few hours and write a decent example app in a few days. Shouldn't be impossible...
Could I use asian fonts like japanese, korean font in the international version of the display ?
No, both languages are not yet available. They plan to include them, if they see a market in these countries.
how much input voltage for the 7" size ?
All Nextions use 5 volt
thanks
You are welcome
Hallo Herr Spiess,
Haben Sie das Display noch?
Mir ist ein IC auf der Platine abgebrannt und ich kann nicht ablesen was da drauf stand. Der Support will nicht helfen und sagt nicht um was es sich handelt.
Könnten Sie mir dabei helfen? Es handelt sich um das Bauteil "U4" und befindet sich in der Nähe des weißen Steckers und hat 6 Pins. Ich konnte nur was mit "6HD" ablesen, aber ich finde nichts darüber.
Eventuell sind Sie in der Lage mir zu helfen.
DAnke!
LG

Bei meinem 7" Enhanced steht IL 6EP drauf. Es müsste eigentlich ein Switching Converter sein. Allerdings habe ich auf die Schnelle keinen gefundengefunden.
Vielen Dank für die Information!
Interesting.
is it in built node mcu esp8266 ?
You can use them also with an ESP32, if you want
@@AndreasSpiess where i have to add esp8266 in dipaly board,is there any provosion for permanent position fixed in nextion enhanced display board..
How long did it take to ship?
I do not remember. Usually about 20 days
You was tapping on the screen to "change time" as the display was asking to "enter password".. Password is 1234 (see it at the bottom of the screen) good display tho
I do no more remember :-(
those leads kept coming so close to shorting.
