Thanks for the video and it helps me a lot decide which product I should go with.
Great. If you need help getting the display working, let me know.
hello mate!! first of all thanks for the tutorials.. just one question it seems that the enhanced has better components from the basic .. would you trust the same both of these or is the enhanced more trustworthy ? thank you in advance
in reliability, they both are the same. I only prefer the enhanced when has a faster CPU, in the models from 3.5" and up.
@@interlinkknight thanks :)
Hello, I wonder if I could use the sdcard slot for other purposes, e.g. for storing data from the Arduino etc. Or is it only for booting the .tft file?
regards
Michael
Sadly the SD card is only for uploading the project file.
Thanks, it is a pitty!
thanks a lot for this video!
I am glad it was useful for you.
Hello there, thanks for the tutorials they are awesome. I could never have worked out my own projects without your tutorials.
Can you please tell me how you got your fonts to look so clean, The nextion fonts are terrible. I have been doing index array off images for my numbers but its would be too time consuming to do all the coding for letters.
If I could get a cleaner looking font from the generator it would be much easier and nicer to look at.
Kind Regards, Paul.
After I made the videos, I realize the font generator takes the fonts from your system. I mean, it takes the fonts that you have on your computer. Install better fonts to your OS.
At min. 1:00 how you have created the indicator’s rotation? Thanks

I have a 3.5" display. When I use the waveform element to plot data from my Arduino UNO, it plots the data slowly. Can we do anything to increase the speed of plotting of waveform, something like tweaking the baud rate or something???
Yeah, increasing the baud does help, but make sure to send data directly without using the library.
Thank you so much!!! Yeah....I usually send data directly using Serial.print() function.....:)
im working on building a digital read out for my lathe and later my mill. can this run the incremental encoders. will be 2 on the lathe and 3 on the mill, and spindle speed encoder. or do i need a seperate micro controler to do the reading and the nextion as display? would like some functions like doing some calculations, abselute positioning. set points and so on.
It can work, but I would do all that in arduino and then just send the values to the display
Sir , any difference in programming the basic and enhanced using Arduino or any microcontroller like esp32 ?
no difference
@@interlinkknight sir, how did you ppay video on the lcd, because as i can see there is no such option to add video in tge software?
Please pay attention to what I say in the video. It's a bunch of images, not a real video
How about Durability? will it work for a project that I'm working on?, at an industrial level?
To be honest, I don't know
complimenti per il video!!!
ho acquistato uno schermo nextion modello "K", dopo aver letto le istruzioni sul sito nextion non riesco a leggere l'orologio, ho provato con "settim.val=rtc6" e "rtc6=3" ma non mi da risultati!!!
potrebbe darmi una mano a risolvere questo problema???
Grazie
What the "K" means?
grazie per la sua attenzione,
la serie "K" è "NX8048K070 Enhanced" che ha l'orologio incorporato, nelle istruzioni nextion ho trovato questo, ma purtroppo, dopo vari tentativi non sono riuscito a far scrivere nessun dato rtc0 = 2017, rtc1 = 8, rtc2 = 28,
rtc3 = 16, rtc4 = 50, rtc5 = 36, n0.val = rtc6
Nextion RTC:
rtc0 è compreso tra il 2000 e il 2099, rtc1 è compreso tra 1 e 12 mesi, rtc2 è compreso tra 1 e 31
giorni , rtc3 è tra le ore 0 e 23, rtc4 è compreso tra 0 e 59, rtc5 è tra 0 e 59 e
rtc6 è tra giorno e settimana 0 e 6 (domenica = 0, sabato = 6)
rtc6 è di sola lettura e calcolato da RTC quando la data è valida.
Un dubbio, ho usato casselle "number" per ora, minuti, secondi, giorni e anno mentre per settimana e misi una casella di testo con i vari "if e else" , L'editor non mi da errore ma quando carico il programma sul display non va!!!!
Did you tried my example on this video?: th-cam.com/video/7Dkn3t_jjN8/w-d-xo.html
hello, maybe is little old video but i just start idea with this display, but one big question is, can you power by battery? so that you have on pictures and no cables? just battery and scrolling from page to page...
Thank you for info
Of course. It needs 5V
@@interlinkknight this i found that Nexton recomend 5V 500mh but is hard to found small battery like for phone 5V and 3.7V are more common but this will not work... Any suggestion, i was looking first on Aliexpress
That's never a problem, man. Use a buck converter, or boost converter or a voltage regulator to get a steady 5V.
Is there any difference about the touch glass quality?
No
Is this possible to replace the displays in those? Is this standard 40 pin connector?
I have no idea
thanx for your video,so i have a quastion , i wanna connect tow nextion with arduino uno for the same data (rx tx arduino with rx tx nextion1 and rx tx nextion2) it is possible or not? thanx
Yes, it's possible. But if you need to receive data from any of the display, then it might be a little complicated. So if you only need to send data to the displays, then don't connect the blue cables (TX on the display) to anything.
InterlinkKnight. Thanx my friend
I am here to help.
Hi Buddy,
As usual nice video. I am in a project wherein i am trying to communicate between two nodemcu. One of the nodemcu(A) is connected with Nextion display thru' TX RX pins and this nodemcu acts as a station , the other nodemcu(B) acts as a AP/server . The objective being a button pressed on Nextion display connected to nodemcu A should wirelessly switch on an led connected to nodemcu B. i have created the sketch , but need someone to check it as it does not seem to work, can u help me out?
I can help only in the nextion aspect, but the wireless communication between two nodemcu (whatever that is) I have no idea. Try my sketch on my 2nd video tutorial and start from there. In that example I turn on the LED on pin 13 of arduino with a button on the display. It should help you. If you need more help about the display, email me.
hi , i have a requirement where i need to connect this display to a wireless controller like esp 8266 and make a chatting interface on nextion display that is able to send and recieve messages from firebase using internet http get and post requests , is this possible with esp8266 or do i have to integrate arduino or some power management supplement to manage stuff , and also can you suggest me if i shd go for basic or ehanced version of nextion , thanks!
I think it could be possible, but I don't have experience posting text with ES8266 on the internet. To me looks like a job for something more advanced like raspberry pi.
The basic version of the nextion display works just fine for that
One thing that annoys me about the standard nextion gauge is the flicker. Is the enhanced version any better ?
Just a bit better but not by much, because of the faster cpu. There's a trick where you write the gauge only when the value changes, which minimize the flickering.
Are you referring to only refreshing when the value changes ?
If so, you showed that, but there was still a lot of flicker. But I wasn't sure if the camera was contributing to the problem.
Yes, that's it. I don't think i showed that on this video, but anyway it does help a lot.
Hello,
I have a problem with the refresh speed of a Nextion screen where there is one gauge and one text field that are refreshed by an Arduino Uno board wich receive signals from an optical sensor wich count the RPMof a shaft. The gauge needle and the text diseappers at every serial transmission during the refresh of the screen. So they blink all the time. I tried 115200 bauds but it the same. The Nextion screen is supplied by 15W power supply (5V - 3A).
In your video at 0:59 , it is clear that there is no problem.
Do you know how to make the refresh quicker?
Maybe you overlapped the text box with the square of the gauge object?
Also, there is always some flickering with gauges. The only reason in my video I show a gauge not flickering is because that's a custom made gauge using images
@@interlinkknight Yes the text overlap the gauge. Thank you very much. I try right now to déplace the text.
You use image for each position of the needle? So it must be a lot of pictures, no? one fore each 0.5°?
In my custom gauge I have one image for each degree. I made it in PowerPoint but you could use something like Photoshop. I have that project available on my video about Arduino tachometer, if you want to see how I did it.
For the normal gauge included on the nextion display, it will always flicker but not too much. But remember to never overlap objects because that, as you saw, cause excessive flickering
@@interlinkknight Thank you very much. I use solidworks to design my gauge picture. And I put color with gimp. I used powerpoint too. But less accurate to draw the gauge picture.
That's great. Yeah, it doesn't matter what software you use to make the gauge. Good luck
is that reliable to use that in industrial place ,or it just for education and fun ?
I never put it in an industrial use so no idea
Question - I found nowhere the max refresh rate of that screen - I need 80Hz - possible or look for a different screen.
I don't think you can get that fast on this display. You need something more powerful like raspberry pi running a display by itself
@@interlinkknight Yeah - that might be what I'll hit - i see no other option except buy, assemble, test to limits then decide to lower refresh rate of move on - at least I'll have more hadrware to choose from : ) - BTW - gr8 comparison wideo - I msg you for help if that's ok when I get the screen. I looked at Arduino Portenta but that's budget overkill.
hello man,
i have a question. i have a nextion basic 7 inch screen. i got a project about nextion and i have to do a countdown timer. how can i do this. is it possible with a basic screen. please help me brother.
Of course it's possible. Did you tried my examples? Do they work?
@@interlinkknight I tried your all tutorials but i did not find a solution. I tried rtc codes but they are not working on basic models. Is there any code of countdown timer.? I want to do countdown timer on nextion editor so without arduino. Which your video can help me?
All nextion displays have timers and variables built-in. Try creating a simple timer with 1 variable and 1 timer. In the timer you can set to run every 1 second (1000 milliseconds) and in the code of the timer put something like var1.val=var1.val+1
That will increase the value of the variable by 1.
All this information is on my tutorials already.
@@interlinkknight thank you my brother. İ will try all. Accually i am a mechanical engineer so i dont have so much information about coding. Thank you so much.
Little by little you'll learn. Use my examples as guide, and take what you need. Pay attention on the code inside the timers in my examples. The code is similar to arduino.
Hello, does somoene know if it's possible to directly convert a HMI made for nextion enhanced to a HMI made for a nextion device of the same size but not enhanced?
in the nextion editor select your display
InterlinkKnight hello, thank you for your answer but i meant can I change my type of device even of i alread start to code on another type?
of course
wow, i bought the 3.2 inch version because it was the enhanced version.
though only the 48mhz version...
good brother amazing
mcu can connect old program display
could you make a video on hardware monitor using the nextion please.
I don't know what you mean
My appologies. I want to monitor my hardware i.e. cpu and gpu stuff. So grab the info from msi afterburner or something and display it on the nextion
That kind of thing is an arduino issue, not nextion display. I mean, I teach how to send data from arduino to the display and vice versa. How to get that information that you want is something that you need to figure out with arduino. Ones arduino gets the data that you want, sending it to the display is trivial. I don't know how to send that information (CPU, GPU, etc) to arduino.
I have seen several people doing it, they wasn't full tutorials. Im not that versed in arduino sketch. Are you willing to help and possibly learn it as well?
Sorry but I don't have that much free time, and I am in the middle of a few projects. I just can't spend time learning how to transfer that data from the computer to arduino. I am sure you can find what you are looking for on the web.
Thanks for the demo. Need to work on the English. The accent is pretty bad. Keep trying, and keep up the good work.
