Please join me on my journey of creating a digital dashboard for an electric motorcycle. I will post all my findings and progress here, and hopefully, the last video in the series will be the motorcycle with the new display. You can read more about the motorcycle here - devs.bike/page...
Currently, the motorcycle uses a segment display and shows only basic information. The plan is to replace it with a full-color LCD panel, make it better looking and perhaps show more details.
As a first step, I´m evaluating possible displays for the motorcycle. Since Arduino is not capable enough to drive a full-color LCD (and I don´t have time to learn new microcontrollers), my safest bet is to use an "intelligent display". There are two requirements - it has to fit into the current enclosure, so the size needs to be around 4.3", and it has to be sunlight readable - i.e., to have a brightness of at least 800nits. There are 4 displays that meet the criteria:
Display Visions - www.lcd-module...
DWIN - s.click.aliexp...
Stone - s.click.aliexp...
4D - 4dsystems.com....
Nextion Display - s.click.aliexp...
Unfortunately, the 4D Display is out of stock and will not be available in the next 5 or 6 months. Since this project needs to be finished sooner, this display is already out of consideration.
There is one more Intelligent Display brand - Nextion. The Nextion display is very easy to use and one of my favorite displays, but unfortunately, the brightness is only around 300 nits. So it´s definitely not sunlight readable. I´m still including it in this video since, again, it´s probably the easiest to use, and someone might find it suitable for some projects.
If you have any questions, please put those down in the comment section, and I will try to answer those there or in the following video.
Thank you very much for watching my videos, and I hope to see you soon! Good luck with your projects.
Do you like the video? Please consider buying me a coffee ☕, thank you! www.buymeacoffee.com/upir
Excited to watch this process. Thank you.
Thank you for your comment, hopefully it will be a ride 🙂
Everything about this is Beautiful. Congrats and thank you for sharing this moment in history with us. This is super neat!
Thank you for such a nice comment, I really appreciate it!
Lo seguiremos. Bonito proyecto. Un saludo desde España
Thank you, stay tuned!
Oh heck yeaaah, I'm so looking forward to this project and your guidance for anyone to follow along 💪🏽😎
Awesome! Thank you!
Awesome ! can't wait......cheers.
That’s great to hear, thank you!
I've made some car gauges, can't wait to see what's coming.
Cool! Do you have something to show? I would love to see it.
So cool. Really looking forward to more episodes of this series. Thanks.
Thank you, that´s great to hear! Stay tuned and I will try to record a second part soon...
I started watching your videos, cause I am developing a custom dash for a motorcycle, haha. Looking forward to future episodes.
That´s great to hear! Do you have any example of what you are working on? I would be very interested to see it!
@@upir_upir it’s a very simple speedo, just the speed numbers and odometer. But it’s working as a heads up display, so needs to be a custom font so I can invert it. I’ve recently decided to use a ESP32 TFT display, so I’ll make it a bit fancier.
Sounds very interesting! Do you have any photos of the project?
Can't wait for the next videos!
That´s great to hear! :)
Increíble proyecto, que ganas de ver como progresa y en que podemos aprender.
Thank you!
Some of these HMI boards use displays with non-square pixel pitch. Worth checking the datasheets for the particular panel component used. This I found to my cost when circular guages appeared annoyingly oval. Unacceptable if you are a bit OCD. I've tried a few panels with LVGL and have found that the biggest culprits are 4.3" 800x480 types with the ST7701S or similar RGB interface. All the 5" models were perfect.
Thank you for your comment, I have learned this lesson the hard way - the Nextion 7-inch display has non-square pixels to the point that it´s very visible, you don´t have to have OCD. So it´s sitting here on the shelf and will most likely never be used for any project :/ From that time, I always check the datasheets.
@@upir_upir OK, I'm glad someone else has seen this and finds it a problem - if you search the issue it seems that nobody has noticed or nobody minds. The big question is: why would a manufacturer build a display with a pixel pitch other than square? If the display is designed purely for video playback then I do understand (new old stock perhaps) as there are some standard aspect ratios to be catered for and respected but the days of doing that with hardware are really long gone. Thankfully, any circular display - such as the popular 2.1" IPS ST7701s is guaranteed to be good (it would look pretty stupid otherwise). The also popular 4" square ST7701s 480x480 is almost square pitch but not quite 0.146 : 0.149
It grinds my gears but I'm not sure others notice it.
I've also found (in my experience) that any display which uses the 16/18 bit MCU parallel interface with integrated frame buffer is usually precisely square px and I think the reason is that these panels are targeted at computer graphics applications using host draw functions whereas the much cheaper but great quality RGB parallel displays which require an external frame buffer are historically associated with video playback where screen geometry is mailable via software.
@@nikthefix8918 Truth be told, I probably do have OCD :)) But I see your point, it drives me crazy seeing non-square pixels. I believe you assumption is correct, all the intelligent display manufacturers are sourcing the actual display panels from various places, and since they mainly look at the price, unfortunately sometime the pixels are not perfect squares. However, what surprises me even more is that people are using those displays and not really care that square is a rectangle and circle is oval. Horrible!! :))
Very nice channel! We've met at ew23, at Proculus Tech booth :) Hope to see more videos about smart displays!
Thank you for your comment, Marcio! Yep, more videos are coming soon :)
Good luck pak!
Thank you!
this looks great!
Thank you!
Looking forward to the next part! It deals with rendering itself?
Yes it does! That´s the whole point of "intelligent" displays - you don´t have to worry about the rendering, so you can controll it with some cheap and slow microcontroller like arduino..
It would really awesome if you make tutorial on MIPI DSI display and External DRAM as frame buffer someday.
Interfacing MIPI DPI displays is on my to-do list for sure, but there is a looot of things there :) Hopefully sometime in the future.
I am also developing a graphical display for electric motorcycles but for much smaller bikes like surron, I mainly used ESP32 development board with displays which are good enough for development but they also suffer from brightness problems, my solution was that I changed the display on the development board, I thought since it uses the same interface(rgb565) it should work and it kinda did but there were crealy problems with horizontal sync since I can change horizontal sync frequency in code it shouldn't be a problem but in Nextion I don't know if this is possible.
Nice design, cheers from Brno :)
This sounds very interesting, thank you for your comment. Do you have any examples of your work? I would surely love to see it. I agree that most displays suffer from low brightness, I don´t think you can easily replace Nextion display panels with a different ones because of the problems you have mentioned - the timing might be different and it would not work properly. The displays from Display Visions have a great brightness, but they are not cheap.
@@upir_upir Yes, I have It's called R.OS vesc display on endless-sphere everything is documented there I don't know why YT kept deleting my replies so switched to my college account
Hi Upir, I love this video, but have I missed your follow up video? I wish to make a similar display for an aircraft, but I don't have your skills, so I am hoping that you can show me the way. Cheers, Tom
Hi Tom, you haven´t missed it - I just haven´t recorded it yet. There are some technical issues with the project. That said, please feel free to send me an e-mail and I can give you at least some guidance.
Your last screen from Stone has the disadvantage that the colours change with viewing angle. But is this really a problem when the gauge will always be viewed from the rider's position so the angle will hardly change?
You are right, but I just hate TN screens. If you put the TN screen next to the IPS screen, the difference is just obvious without the need to change the viewing angle. The IPS screen has richer colors and it´s nicer to look at. Of course the OLED screen would be even better, but I haven´t yet found intelligent displays using those.
Lol, my guess was that your requirement was to be able to drive it with an Arduino! Kinda missed the boat there, but also bang on :)
You were not completelly off, since Arduino will most likely be used :)
So did I miss it or is there no next video? Want to know how the project turned out.
You haven´t missed it, the second video is not out yet - there were multiple delays with this project, but hopefully now things are moving in the right direction. I should have some update soon.
Excelent project, Years ago, I started a similar project for a car, selected and played a lot with the Nextion display until I figured out, it will not work properly in day light, from then, I just put the project aside after buy some brighter displays but not "inteligent" (wich allows beautiful graphics and fast response but at a higher prece point), still not played with them. interested in see, how your project evolves.
grretings from Italy😊
Thank you for your comment! Your project sounds very interesting, is there perhaps something more that you can share about it / photos / more details? Unfortunatelly the Nextion displays are very easy to use, but the display quality is not so great. Which is a shame, otherwise, it would be my preffered display to use.
@@upir_upir yeah, the Nextion is very easy to use, I communicate directly with it using simple serial commands and not their library wich was at the time, hard to understand and bulky. For indoor projects, I think is a good and cheap solution for anyone without high knowledge of programming like me. I do not have uploaded anything of my projects inline, but if you need some info I can provide to you. My project was based in a 4.3" Nexen extended version, developed the graphics and code in their IDE simulator, only after a year, I bought the real display with a couple of 2.8" wich I developed a dedicated PCB to hook back the display board. Was an interesting project, but never finished. Was based in atmega328P, all the filtering necessary to cope with the automotive enviroment in the power supply, a pair of NTC temperature sensor with all the filtering and pullup resistors, 3 analog inputs filtered, a RPM signal process circuit and some output pins trough a darlington (ULN2003), all that in a 2 layer Board and parts only in one of them (back in the 2.8" display, with the 4.3" just played a bit using a simple arduino simulating data trought the serial), that was a good challenge, but, only to figure out, the nextions displays are only for indoor use.
Now I have a couple of Chrystalfontz high bright ips displays but they are not intelligent, the 2.4" is SPI and the 4.3" is command in RGB mode(wich need a bunch of IO pins) I think, but not played yet any of them, in this case, I need to create a full new PCB, allocate parts in 2 layers (or do 2 boards) and place FCC connectors for the display and the touch, code everything... The 328P is not powerful enought to do with the graphics I get with the Nextion, and for many reasons plus these, the new project is abandonned. Hope this year can start it again. If I can help with info, don't esitate to ask, I will be happy to help you. Cheers
@@hiperformance71 Thank you for your very detailed answer, too bad you haven´t recorded anything, I´m sure there would be many people interested in your project, even when it´s not finished. Have you considered switching to some different intelligent display, like the DWIN ones? Those are very similar to Nextion, but they have high-brightness IPS screens that look great. They also run faster compared to Nextion, and they also use the serial protocol to communicate with microcontroller. That way, you can possibly still keep your old setup and only exchange the displays? Let me know if you would be interested in cooperation on this project. I would be happy to help with the display side of things...
Love it. I found this after watching your other OLED gauge video. Commercial options do not work for me. Either features are limited or the cost is not affordable. I have thought too much about the screen- I'll keep investigating a way to utilize a smart phone as you get an incredibly nice, weather resistant and high nits screen that is not otherwise available. Keep sharing your work please!
Thank you! What are your trying to achieve with your project? Trusting of Smart phones is surely an interesting option.
@@upir_upir I thought about it far too much and made it way too complex. I'm now just using realdash on my phone. And am going to use an arduino Every board to take the analogue and digital inputs from the bike, convert them to can and send to the phone via OTG usb. Could use Bluetooth but I like the idea of a wired connection more (it needs a power connection anyway). Will use opto isolators on all inputs to Arduino and a bare bones ROM on the phone to run in the background. Still lots of things to work out but the phone was too good to pass up as the basis for a dash. It even auto adjusts for brightness! Basically everything you could want is already there!!:-D
@@nathanchalecki4842 Sounds very interesting. Do you have any photos of your project/setup? Thank you!
@@upir_upir not as interesting as yours! There is not much to see with mine, most of my time has been spent getting the realdash serial Data to flow between my phone and the Arduino, and figuring out the can frames etc. Pretty steep learning curve. I can flash indicators etc on my screen by pushing an arduino button so that's a good bit of progress for me.
@@upir_upirokay, I have had to quash the phone idea. Boot times are obviously terrible and android just doesn't reliably support automatic start of applications on charge power, etc. 😢 It works like garbage, basically. The display visions screens look great, I'm looking at those now. A decent weather proof enclosure is the hardest part of the whole thing so their glass cover and flange is a great system
are you making this for one bike or you bring this to production!?
Hopefully for production, but at the same time, it will most likely be just a few bikes. It´s hand made and they don´t plan to produce too many of those bikes..
I'm thinking about the same project for honda cbr650r but as additional display. I have a question. How will you communicate with the bike? CAN or ELM327 (bluetooth)?
Sounds like a great project. What are you trying to display? Is there something that is not displayed on the built-in screen? I think we will go with CAN, since everything is very close together, there is probably no need to use bluetooth..
@@upir_upir My plan is to create a system similar to Android Auto. I aim to display the accurate cool temperature and a steering control interface (eg/ cardo intercom, music, etc). I plan to utilize the ESP32 or STM32 microcontroller, MicroPython programming language, and the LVGL library for the ui interface.
Please make a video on types of displays compatible with Arduino including the use of laptop monitors or screens
Arduino is too slow to drive color displays directly at a reasonable speed- like the mentioned laptop monitors. So the best approach for Arduino is to use the intelligent display, as mentioned in the video. I do plan to record another video with more details about how to interface those displays.
Hi, I needed help on how to create an animation for a speedometer in Nextion. Or where can I find the finished project
This particular project is not finished yet, but since this a commercial project, it will not be published for others to use. Also, I´m not using Nextion for this project. That said, I have a few other videos using Nextion displays, please check those for a better understanding on how those things are done. Good luck with yout project!
please , make video or share resources
about the making of gauge for theh speed
Yep, that’s exactly my plan.
Hey! Any updates? We're urging for news 😅
I wish I could say I have some updates, but it´s on hold. I will try to keep it moving and post some progress soon..
Sounds great! I'm doing a custom speedometer for my electric Chinese Vespa and the current situation is just like yours, trying to find a 3.5 inch screen with at least 800 nits. And I also want it to show turn by turn directions from my Google Maps. Not much progress besides the main interface so far. I have a working prototype with a 16*2 screen.
Hope that won't destroy itself in bad weather conditions, moisure is bitch to deal with
We will see, hopefully it will last at least a few rides :) Do you have any ideas how to make it weather/moisture-proof?
@@upir_upir Not a clue. I'd imagine sealing it but then you have to make sure you don't get any moisure inside or else screen might fog. I'd test it before you make more than one-off, in bike the worst case is whole screen getting splashed by water... for entire drive
I also remember Tesla getting into problems because they used consumer-grade screens that were not rated for the amount of heat in the car and failed. But those intelligent screens might be fine for that, the Nextion appear to be rated all the way to 70 C and even to 90% humidity.
Sealed case with transparent front and some conformal coating *might* be enough, just need to care on how you're getting cable in so the water can't seep into it
I'm sure you figure it out (or might just get lucky and start with design that just does it fine) but be sure to do some a bit more extreme testing before making more than one unit (I assume your "friend that makes electic bikes" will want to make more than just this one off)
Also one fast MCU *might* be just fast enough to drive LCD on its own with simple UI if you want to save a bit $, but that's probably much more work than those "intelligent" LCDs
Very interesting project. Is there a follow up video?
Not yet.. there are some technical problems, but hopefully I will be able to finish it one day.
@@upir_upir Sad to hear. I have the same project right now. What problems do you mean?
very nice project! do you have updates on this one?
Thank you, but this project is on hold for now. I hope it will be finished one day..
@@upir_upir would want to give my scooter a similar display , too, but has an option for a gps speedometer🙂. I'll wait for you tutorials👌
Have you heard about the ESP32 TouchDown? ;)
Not until now :) It looks interesting, but unfortunatelly I haven´t found any additional details about the used screen. I don´t think it would be sunlight readable :/
Any progress on this project? I'm also looking to create a CAN display. Thanks!
Unfortunately not much of a progress, but I hope to get back to it again. Are you developing it for a car or a bike?
@@upir_upir I am working on converting an old Baja SAE car to electric. I'd like to put together a display/arduino setup that can read the CAN messages from a Sevcon motor controller to display things like battery voltage, speed, motor/battery temperature, etc. This project seems like almost a perfect parallel!
Can you make some video tutorials with raspberry-pi and displays❤
Raspberry PI is on my to-do list for quite a long time, and I hope to get to that soon, since I already have a stack of PI laying around :)
@@upir_upir wow...❤
so whatever came of this project, i cant seem to find any other videos on it
Sadly, there is no second part - yet. This project is progressing very slowly, but I will record a video once I have any new findings.
@@upir_upir in that case, I know you have the GPS speedometer tutorial, but have you looked into using a hall effect switch and a magnet mounted to the wheel to get a wheel rpm and some basic maths to get that to read out Kph/Mph? I'm trying to do something similar with a bike, to eventually translate it to my own motorcycle. But I am big idiot so progress is only a little faster than molasses in an arctic winter
Hey! How did you change the number with the speedometer. Will you tell me?for dwin dgus.
You need 10 images of digits, that´s all. I might cover this in the future tutorial.
@@upir_upir how did you do the layering. I use icon animation for the circular progress bar but when I trying to put the changing number animation on the top of that I can't see any number animation on the virtual screen but I can see the circular progress bar in virtual screen.. The circular bar is working. But the number animation is not showing. Any suggestions?
Thx so much man if u show how to drive nextion with arduino, i find it so difficult i gave up because there’s so few documentation and help for this niche display… if u could get it to print values from a sensor or something like that, i’d by really thankful man. Awesome project btw
Thank you for your comment, I do plan to record video with Nextion display soon. What kind of sensor are you planning to use/ do you have any specific project in mind?
@@upir_upir i didn’t have a specific project in mind (or i did actually, it was a smart plant project where the nextion would display the soil humidity) but reading any variable and displaying it on nextion in general is what i struggled with
Is there any possibility to use it on DEVS Type 6 bike? Is it reason why you make it?
Yes, that´s the reason, and hopefully it will be announced soon (=this week)
What are your plans about weather resistance? Isn't touch function kinda useless in a bike? Or do you intend to be Bluetooth compatible, giving android auto/carplay function of sorts?
The display will be sealed, we will see if that´s enough or not.. I don´t know if the touch will be used or not, and if so, than only for some simple settings liks the screen brightness. The thing is that except for the DWIN displays, all the other brands always include touchscreen, whether you use it or not.
Are those displays rated for automotive? Are you considering as requirement e.g. bigger temperature range and especially vibration resistance?
They should be all rated for industrial usage, so hopefully it will be enough. I’m not too worried about the temperature range, as you will most likely not drive a bike when it’s freezing cold, but as for the vibration, we will see…
I REALLY look forward to this project because I was looking to develop something very similar for my car. I want to convert the analog instrument cluster in my car to a digital one.
One question: how do you intend to protect the screen from the weather and other environmental elements?
That´s great to hear, do you share any details about your project somewhere? I would be quite interested to see more.
I would mainly work on the graphics, my hope is that the screen protection would be done by the bike manufacturer. I will still share the details once I know more.. .
@@upir_upir I haven't really started properly working on the project, so there are no details to share at the moment. Now it seems I will be following in your footsteps.
hello friends, we have developed something similar to this, we have made the display of the Mazda rx7 car digital, if you want to see it, you can contact us.
Could you post a link to your project? I would be surely interested to see it
@@upir_upir If you send me your contact address, I will help you.
Where's your update :-)
Well, about that... it takes little bit more time than expected, but I hope to have an update soon..
I was just emulating elm327 wifi on a esp8266 just 2 days ago
Cool! Was that for some specific project?
This nexion displays?
They work with vector graphics?
You can use vector graphics with Nextion display if you convert it first to font file, however, it´s oftentimes much easier to just use bitmap grapics instead.. What are you trying to achieve?
@@upir_upir I need animated manys graphics primitives in real time(without delays) - for very precise devices.
In that case, Nextion displays are probably not the best option.
@@upir_upir Nexion display like "framework" for rapidly DIY.
I think need use separetely chip MCU + display.
Yes, nextion is great for fast prototyping. For your case, non-intelligent display would work better.
I want to be like you im intresetd
Thank you, I’m glad you are interested. I hope to record another part of this video series soon..
I use your gauge coltroller lesson with nodemcu...it is amazing thanks man...❤
E motorcycle!
Yep 😀 are you planning to get some?
