Nextion+Arduino Tutorial #4 Custom Gauge And Play Video

[@syedminhazuddinrizvi3068]

Finally something to install in my car.. I always wanted a digital display instead my analog gauge.. thanks..

[@RuiSjm]

Very good job! Thanks a lot, i liked the "no nextion library" in sketch, very simple and clean!!

[@alicamping24]

Gauge how segmentation and to extract your background picture?I would appreciate it if you know if there is how? photoshop...?

[@interlinkknight]

I made it in Photoshop and PowerPoint, but I don't recommend it because it's not an ideal software for that

[@AntenorMoriniJunior]

Well, how cool is your initiative, I have an old car with a carburetor and I would like to implement it in its instruments, where there is already a digital clock display, basic functions of an on-board computer and include temperature, oil pressure or quantity of fuel. I studied electronics about 20 years ago and I know that with Arduino I can implement it, but I'm not in the business, maybe with the material that I made available, thank you very much !!

[@laurencemunro]

Well done, I am not sure I am prepared to make the effort, but you thought outside the box! If only there was an easier way to get this done... Good job!!!

[@leonamor8662]

Very nice video, how did you manage to make the images change depending on the received value inside the NEXTION editor ?

[@interlinkknight]

It's simple. The nextion editor has a variable and then I run a timer (loop) that runs a piece of code that puts the correct image depending on the value of the variable. If you open my project, you'll see

Nice. Is there a way to refresh a needle ONLY if it's value has changed else not update needle? Then it would not flicker.

[@interlinkknight]

Yes, that's totally possible. Actually in my example file from my first video I did that for the gauge: kzbin.info/www/bejne/rXq6qYaCi6Z0h6c Even though that minimize the flickering, it doesn't prevent it completely. Eventually when the gauge refreshes, it does sometime flicker.

Technically you could try it on the basic version, but you would probably see it more lagy, with less FPS.

[@talhayousuf4599]

Thanks sir, one thing I must ask : How did you make those so many images for the gage with needle. Is there any way to produce those interpolated images?

[@interlinkknight]

Powerpoint. But i would suggest something like Photoshop

[@Gastex75]

fantastic example and approach, just a question about memory... I have similar approach and similar ttf file size, but on my 3,2 screen uploader said: file is too large. memory it seems to be 4mb, but file is 20! What is my mistake? Do you have some suggestion? thanks in advance

[@Gastex75]

ok, I saw the spec of your display, and ok, your model has 32mb probably, I have 5" display also and probably this will be ok.

[@interlinkknight]

Yes, the 3.2" enhanced display has 16MB of flash memory. I have the 3.5" enhanced so it has 32MB. You own the 5" enhanced display? Why are you talking about the 3.2"? Or do you have both?

[@Gastex75]

I am working to make some test on 'little' 3.2 basic and I am waiting from ITEAD 5" enhanced display... so I am working now with 4mb.... and 2/3 pages fill the memory.... I have a gauge based on RPM bars.... And I think that is not possible to load all images in 32mb, because images allocation is 10mb, but ttf compiled module will be 96mb (it uses RAW image format) :-) so I am working to draw the bars... it seems to work on 3.2, I will see on 5".... thanks for your support

Ok. Good luck

You can put multiple gauges in any part of the display. You are limited by the flash memory, though.

​@@interlinkknight hello. Did you mean flash memory of microcontroller? I want to make small animation with Basic Nextion.Where to store pictures?

[@MrCiuffoly]

I would like to use this method to create a vu-meter for hi-end audio systems but which is the time to load the background image ?

[@interlinkknight]

Depends on the resolusion of the display and it has to be enhance version. Mine is 3.5 inch and you can see in the video that it loads the images really fast.

[@mattnsac]

Do you have and example of this code without a delay? I have come to find that your examples work better than using Nextions library, but using delay while reading actual RPM, MPH or KPH is a problem as a 20 mSec delay is a compounding problem. Im wondering if this should be used with millis() instead of delay?

[@interlinkknight]

You mean the small delay on the arduino loop? I put it because the nextion display doesn't like when arduino sends data too often. I suppose you could create a millis delay to send data less often. But let me tell you, I have used rpm sensors before and never had a problem with delays. Use interrupt pins.

[@DJDevon3]

If it supports alpha transparency then create images of only the needle. That way you aren’t redrawing the entire display just the needle. Could save apu power to be used elsewhere. 😁

[@interlinkknight]

I said it doesn't support transparent images.

refresh the gauge only when the value changes

Yes, it will flicker no matter what you do. I did my gauge with powerpoint and photoshop. I am not very good with graphic design so I can't give you advice about that.

Start by using my example files for my 1st video tutorial. When that works, you could give my custom gauge a try.

Hello, I tried Your example files and it works very well. After i tried to write a code with your examples, and i would like to show the temperature on the display (it is not work). If i go on the serial monitor from arduino, i see the temperature but not on the display. I hope You can help me.. #include "Nextion.h" #include NexNumber n0 = NexNumber(0, 2, "n0"); double Thermistor(int RawADC) { double Temp; Temp = log(10000.0*((1024.0/RawADC-1))); Temp = 1 / (0.001129148 + (0.000234125 + (0.0000000876741 * Temp * Temp ))* Temp ); Temp = Temp - 273.15; //Temp = (Temp * 9.0)/ 5.0 + 32.0; return Temp; } void setup() { // put your setup code here, to run once: nexInit(); Serial.begin(9600); dbSerialPrintln("setup done"); } void loop() { int val; double temp; val=analogRead(0); temp=Thermistor(val); Serial2.print("n0.val="); //serial2 = because my display is on serial2 Serial2.print(temp); Serial2.write(0xff); Serial2.write(0xff); Serial2.write(0xff); delay(1000); Serial.print("Temperature = "); Serial.print(temp); Serial.println(" C"); delay(1000); }

[@interlinkknight]

Looks like you forgot to initiate Serial2.begin(9600). You started Serial for debugging, but not Serial2. You need Serial2 too. Why are you using the nextion library? You should delete everything there about the nextion display, except the following: void setup() { Serial2.begin(9600); } void loop() { Serial2.print("n0.val="); //serial2 = because my display is on serial2 Serial2.print(temp); Serial2.write(0xff); Serial2.write(0xff); Serial2.write(0xff); }

very good!!! im having trouble when loading the .hmi file u provide from the description, the nextion editor says wrong resource, can u help me please.. thank u

[@bramSDASCL1759]

sorry, i guess because im using the basic version, not the enhanced version :(

[@interlinkknight]

Yeah, you need the enhance version because it uses a lot of memory

[@JerkerDahlblom]

So those gauges are onboard, what about sending bitmaps to the Arduino and show them that way? PC => Bitmap => Arduino => Nextion using USB Bulk Transfer. Is this feasible at 40fps? I have never done anything Arduino related but I am looking for hardware to do a project for flight sim gauges.

[@interlinkknight]

That's not possible. The nextion display can only receive commands, values and text. All the images, layout and text boxes and everything should be already on the nextion display, created with the nextion editor. If you have a flight simulator and want another screen for gauges, I think is better that you add a normal computer monitor (small) and show the gauges there, driven directly by the computer and the simulator itself.

[@JerkerDahlblom]

Dang.. Well I'll keep looking more other alternatives. Thanks for you help!

[@rampy4963]

Is there an automated way of producing a series of gauge pics? I've made a gauge in Inkscape using the SVG format, however it is very time consuming moving the needle/dial each and every time then exporting the pic.

[@interlinkknight]

Sorry but I don't know a way to automatically produce the images. I spend a lot of hours to create mine.

[@rampy4963]

Thanks. I just tried it on a non-enhanced 3.5inch display. It still flickers noticeably. I think the enhanced version is the way to go.

[@rampy4963]

It still is a big improvement.

[@interlinkknight]

Yeah, that's what I thought. Keep in mind that not all of the enhanced versions have the faster CPU. Only the 3.5" and up have the faster CPU. I bought the 3.5" enhanced version for that reason. A faster CPU is important, in my opinion. What if you use smaller images for the gauge? That helps with the speed/flickering? Thanks for sharing the results of your test. It's good to know.

[@rampy4963]

I might write a program that allows you to hook in on the ID of the needle in the SVG file, then automatically rotates it and exports each individual image.

[@jamest.5001]

wouldn't it be possible to make a speedo and other gauges? maybe use 3 screens . have the tachometer and speedo on one each. then fuel level. oil psi. h2o temp. and volts and or amps on a single large display. or would all the gauges on a single display take to much memory? great video I love the idea of creating custom gauges. especially with the graphics .. PS I'm a total newb. but I'm learning every day.

[@interlinkknight]

My project with the gauge I show on the video uses 20MB of flash memory. The maximum memory available is 32MB, and there is no model with more memory than that. You could do something like you describe, but with smaller gauges in a display no bigger than 3.5". Or just use the included gauges that you can add on the nextion editor. They flicker, but if you refresh them only when there is a new value to show, they flicker a lot less. But at least you can add as many gauges as you want without worrying about running out of memory. Maybe you could do the tachometer and speedometer with custom gauges, but both smaller than mine. And the rest you could use the traditional gauges or progress bars. You would have to test.

[@TheMcSebi]

Unfortunately the only way of displaying two (and not more than two) gauges over each other is to use method 1 for the first, and method 2 for the second gauge....

[@interlinkknight]

Your comment makes me happy. Thanks for sharing. Is nice to see I could help. The image format is not that relevant. I try adding different formats into the nextion editor and the used space was the same. Apparently gets converted into whatever format they use, no matter what image format you put. Are you going to create your own gauge? If you do, which image editor are you going to use?

[@reneeberty]

Exactly, they seem to be using BMP, but they says png is coming soon, I can image how transparency will add realism to the future designs. I am actually designing my gauge background pastern on Photoshop then needles or progress bars will be animated using your example. So Helpful..

[@interlinkknight]

Let's see if they can really make that work with transparency. It would be cool indeed. Good luck with your project and if you get it to work, maybe upload a short video and share it with me please.

[@reneeberty]

Sure . let me ask you this do you think an arduino mega can handle 2 nextion display?... I'm kind of crazy beginner... We could exchange ideas by mail if you want..

[@interlinkknight]

I've never used an arduino mega using multiple serial ports at the same time, but I don't see why it should be a problem, especially if you are only sending data to the displays. If you need to receive data like using touch-screen buttons, then might cause some issues. You would have to try. Worst case scenario you could use two arduinos, one for each display, and put a connection line between arduinos, with something like I2C. Or maybe two displays could share the same serial port? I don't know. You can email me my-user name/youtube-channel-name at gmail.com or click the contact button on my website.

The format is png, but I have the problem also with bmp.

@@interlinkknight dont work cant open arduino say but i find the file thanks. i want to ask you something. if i dont want to work gauge with potentiometer but with my can bus. the example is that. include #include int data; char buffer[456]; void setup() { Serial.begin(9600); Serial.println("CAN-Bus Test"); if(Canbus.init(CANSPEED_500)) { Serial.println("CAN Init ok"); } else { Serial.println("Fail init CAN"); } delay(1000); } void loop() { Canbus.ecu_req(ENGINE_RPM, buffer); Serial.println(buffer); Serial.print(""); delay(10); } the code show me the value with buffer how to do work this buffer with nextio gauge?

[@interlinkknight]

Sorry but I can't help further than this. I have no idea where that code came from. I only can help with my code

[@Sodwmistis]

@@interlinkknight at your code i have problem. i dont find how to work your gauge with out potentiometer. the value from the potentiometer i give him from serial port and not from analogRead. thanks and sorry about my question and for my english :D

[@interlinkknight]

I don't know how to do that so I can't help

[@franciscocasas2082]

So useful, congrats. BTW do you know how to place some other object over a picture pe in this case the gauge, because I tried but at first image update disappear the other objects, I need to do a timer like this one cdn-images-1.medium.com/max/1600/1*Y2La3-gXvH_8xWOcRG_HwQ.png (in progress section).

[@interlinkknight]

Sorry but that's not really possible. One "rule" for making nextion projects is never overlap objects. The moment you update an object, is going to hide the other object. It will flicker. The only way to maybe do this is by dividing the background image in sections to leave an empty space in the middle, but this is time consuming and make things more complicated.

InterlinkKnight thanks I'll take it on mind

[@jxlin9680]

Why can mov?

[@aldinmarchetti]

Gracias! excelente aporte.

[@interlinkknight]

De nada.

[@Industry-insider]

I bought the display only for the program to refuse to make a tft file wtf

[@interlinkknight]

?

[@Industry-insider]

InterlinkKnight nvm I didn’t see that it had a compiling error

[@nguyenvansi2912]

How to play video Sir ?

[@interlinkknight]

I explained exactly that on the video. Please pay attention.

[@nguyenvansi2912]

Thanks Sir. I will pay more attention.

[@jpkruger6333]

Very clever

[@Ahmadnaweed786]

the problem with this method is that those images need to go int the flash memory which will take lots of space. liked your video but not a good solution.

[@jenniferdelrosario6643]

Very good job idol

[@rampy4963]
