Yes, I Changed My Mind: Using SquareLine Studio and LVGL Now!

Yes, for many years I refused to use LVGL and SquareLine Studio, but now I have finally learned how to use them, and I like them very much. I am planning to make a series of tutorials about them because it seems this topic is interesting to many people.
My oldest sponsor, PCBWay www.pcbway.com/, will have a birthday soon. We have collaborated for more than four years, and I am always satisfied with their service and products.

[@dfn808]

Looking forward to your SquareLine Studio tutorials 👍

[@nthdesign]

I originally found your channel when I needed help getting started with my T-Display S3 Long. I really appreciate your tutorials and narration style. Can’t wait to watch your SquareLine Studio tutorials!

[@VolosProjects]

Glad to help! Thank you:

[@TheTechRandom]

Can't wait for the tutorials. Your videos always inspire new project ideas!

[@VolosProjects]

Glad you like them!

[@jasonwhite2775]

My man! Good job. I can't wait till for the tutorials. Like I suggested before, please make tutorials where the screen controls some thing like a motor, rpm or relay. Or receives sensor input to display like RPM, temps. and so forth. Your videos are very informative and super inspirational! Thank you for doing what you do.

[@VolosProjects]

Thank you man. I will try.

[@sandrarocha2436]

Yes please! If it is possible add the data record in a SD Card 😊 and/or a web interface. Thank you!

[@doc.scythas]

It's awesome to see this channel growing in subscribers. I love seeing all the gadgets Volos comes up with.

[@VolosProjects]

More to come! Thank you :)

[@tubeDude48]

It's impressive how much you can cram into a display! 👍

[@AMPProf]

Yep even useless blinks and numbers from Scifi

[@SparkofMagic]

Good idea for video series! Thank you.

[@squarelinestudio]

Thank you very much! Great and informative video. Keep up the good work! :)

[@henrybecker2842]

Thank you for telling us about this. I intend to give it a try

[@timbiddulph]

This is the series I was hoping you would make! T-Display S3 AMOLED is a great unit that I would like to use for my project. Thanks!

[@VolosProjects]

Glad it was helpful! Thank you:

[@Tony770jr]

I have looked at SquareLine Studio in the past, but I didn't have a UI project in mind. Some of the tutorials getting the ESP32 with touch display seemed complicated so I decided to hold off. If you can make a decent tutorial, it might help me with a future project. Thanks!

[@christianschmitz2301]

Great explanation as usual. The ESP32 Cheap Yellow Display Board - CYD (ESP32-2432S028R) would be great as target for your totorial.

[@Pele_79]

Thanks for all the great videos, I found your channel from the ones for the M5 Stick/Stack. A tutorial for using the "Cheap Yellow Display" for Squareline Studio would be great, and for me personally with it being aimed towards MicroPython.

[@0miker0]

Great video and I look forward to seeing more on Squareline. To answer your questions, it would be great to stick to one or two generic, easy to get boards with a touchscreen. Anything from lilygo at a good price would work well. For tutorials, things like assigning a function to a button or assigning the rtc chip to the time on the screen would be great.

[@VolosProjects]

Sounds good! Yes i will try to avoid expensive boards. Tnx Mike

[@weimingfeng2284]

More t-display-long examples and tutorials would be very appreciated ❤

[@Thomas-A159]

Thanks for sharing Volo 👍👍 I have installed the SquareLine Studio and tried a few things on my ESP32 board with 2.4” TFT - under Arduino. It works great - looking forward to more projects from you 😉

[@michealmorrow1481]

Which board did you use? I have a T4S3 that I would like to be able to design for. Totally lost how to do that at this time.

[@Thomas-A159]

@@michealmorrow1481 I developed this board myself.

[@MHTSAPAS]

About time! I wanted to show you how to use SquareLine a while back. I've never been one for making and editing videos however and got too frustrated in the process. I guess I'm getting old(er). My coding is nowhere near your level and my biggest issue with SquareLine was that I could spend an hour or a few making great ui's but they never worked once uploaded. Everything was there but touching the screen or clicking buttons never really done more. I thought I would have to edit the code also which after looking at it, was an absolute nightmare. I guess now you will teach me. If you had any idea just how much I have learned from your videos you would be astonished. I have a full lab with everything one would need equipment and component wise. I'm stocked to the teeth with dozens of micro controllers, More LilyGo boards than a normal person could ever need and missing the knowledge hehe. I'm getting there though. Thanks again!

[@VolosProjects]

Tnx man, i glad you learned lot, i hope you will more. Me to, room full of controlers and board. Sometimes is hard to decide what to use.

[@kurtsu]

For your tutorials, please use the CYD, Cheap Yellow Display. ESP32, touch screen are the important parts, but it is easy to find, flexible, and cheap.

[@jeffschroeder4805]

Code generators like SquareLine Studio simplify things but if you are implementing code that you don't develop and understand, you might as well buy rather than make your own projects. Getting there is most of the fun. I love your channel.

[@MaxSMoke777]

Amen!

[@VolosProjects]

yes, i agree. But belive me sqare line is just part of work. There is still lots of coding to conect evrything and to make something functional.

[@alxsouza]

I would love to see you using the S3-Long

[@Zeloverevolution]

Nice video. For most of my projects, running my own code to draw the screen gives me the flexibility I need. But if I find I don't need as much control for a future project. I'll certainly give this a go.

[@VolosProjects]

Yes, i totaly agree. I love to have complete control, i all depends on project

[@eduardofelippone4582]

I would like to see how to use SquareLine studio to program a LilyGo T-Display and PlatformIO under Visual Studio Code. I have tried to design some basic things using this software, but I got a little confused when I had to export and manually copy some libraries to my project (maybe I did not understand correctly what to do). About the project, anything simple to show the basic steps to start a project from scratch and upload it to the board. That would be much appreciated. Thanks and congratulations for what you do.

[@vzerodonuts7949]

Would be awesome, i also tried me with an esp32 s3 round display an wanted to connect it with my phone to display music Navigation and weather on the small screen but dont know where to start :/ …. At least i found this amazing Channel

[@RWB123]

I would find Squareline tutorials very useful. It's something there are not very many of and the software is advanced so watching somebody show off how to do stuff would be beneficial for sure.

[@iot_cdp]

Maybe starting with the popular ILI9341 Touch screen display? Thanks for sharing!

[@Zortan12]

love your vids

[@mrmomos6755]

Looking great as always! Any Chance you could revisit the lilygo T-display S3 long with squareline? I believe nick posted a working lvgl odometer example but I for one have had alot of black screens trying to adapt it myself... Cheers

[@clifforddw]

Be great to see how to interface with non touch boards too. Using a combination of a rotary encoder and the two buttons on the T-Display S3 OLED would be great.

[@reedreamer9518]

I have not used Square Line Studio yet, but I did a few projects using Nextion's display programmer thing. It does have some nice speed advantages in both development and execution, but the major drawback is the hassle of uploading the new code to the display each time I make an edit. The Nextion code has to be uploaded either via SD card or I eventually installed a switch so that the display is either connected to the MCU or the programmer. So how are you uploading the display code with these Square Line displays?

[@joebauer49]

I'm learning and need an end-to-end example of a simple T4S3 SquareLine project, from start to working display. The problem is tft_espi doesn't support it, especially for the Arduino IDE. I don't want to learn IDF right now. Thanks for considering my request.

[@edriobranco]

Nice video! Make videos showing how to upload code for various esp32 board models.

[@sulcusulnaris]

I currently see the biggest problem in the compiler. There are now quite a few DIY projects that can no longer be reproduced because they require very specific libraries and specific compiler versions. If something is wrong, you get error messages that you can't do anything with.

[@lohikarhu734]

Yes, I tried a couple of projects, and I couldn't figure out which version of wifi library, or some others, too... The ESP32 space has become a bit "cluttered", a bit "wild West".... I'm poking around with Rust, and probably try to use ST's IDE, and it looks like NXP and Infineon are trying to get good infrastructure in place, too

[@michealmorrow1481]

While you are on the learning curve, I would surely like to see an end-to-end from start of project to working display for a simple T4S3 SquareLine project. The trouble, so far, is that it is not supported by tft_espi. And, specifically for the Arduino IDE. I can't see going through the learning curve for IDF. Thanks for considering this request.

[@nishad2m8]

Like always, nice video 🤗. pls try to explain how to handle libraries, as I think it will help people with less programming knowledge like me. 😇

[@albie2sharples]

This is great i like square line studios but always have trouble linking widget values to real time data a video on that would be great

[@Spa3tan-ai-content]

amazing just starting out can you do tut on ESP32 Display

[@mgobluevictor]

Which variant of the LilyGO T-Display are you using? That link has a dropdown with many options (V1, V2, touch, black shell, etc)...

[@AksamDar]

I would say use two boards for new tutorial series. Both regular Lilygo T-Display S3 as well as the touch version. If thats not possible than may be the touch version only

[@philletourneau]

It would be great to use the LilyGo AMOLED device, as I don't think there's a predefined template in Squareline for it.

[@paulz8750]

Just a thought - might you get more views if you use a an older display like the LilyGo T-Display without touch for starters?

[@bobby9568]

Amazing! Can you please make a LVGL tutorial from scratch?

[@colingale]

there are also other Design UI apps out there to look at, EEZ and 4D Studio come to mind.

[@annettehanshaw8005]

Genial, esto me da una idea de por donde empezar a buscar, porque no tenía ni idea de como hacer la UI para el T-Display S# AMOLED.

The lack of a layout manager with LVGL still buggs me.

[@johnny14794]

i would love to learn to use SquareLine Studio. But would like to see a working clock with internet weather working for LillyGo displays, from touch to the non touch ones like the S3's, etc. I would pay for it as well. 🤑👍

[@tonynilsson3527]

Nice if you made a stock interface. Where you kan input stock symbols and have them flash green or red depending on if the stock goes up or down. Fetching stock information from Yahoo Finance.

Hi!. Thank you for this video. I didn’t know about SquareLine Studio, but It seems expensive. But I will try it like most of your proyects. Could you share the code of your TDisplay S4 shown in the video?

[@VolosProjects]

hello, thank you Sandra. I will share that project but i still work on it, it have some isues.

[@StevePrior]

Since you do these projects for customers I'm a bit surprised you still use the Arduino IDE and not Platformio. I switched a year ago and find the per project library management, multiple profiles per project, and editor features compelling. Can you comment on whether you've tried it and why you stay with Arduino IDE?

[@VolosProjects]

Yes i used it for more than year and than i switched back to Arduino Ide. Becouse i have more than 100 diferent board,, sometimes in week i do many diferent project with diferent boards .Arduino ide is fastest when i need switch from to another board. Also evry day i got tons mails from people who still have black screen. It is easiest for me to expain what they need to setup if we both use Arduino. Another reason is that i dont care about UI to much, in my life i made so many programs in notepad. Platform io is nice but at the end result is same. I have feelling that many people want to use platform IO becouse they heard it is better, but they shode care more about learning to code. It happens my all the time. I spend few hours to helps them to install and setup platform io and later i realized thet they are completly beginers. But this is same in every hoby, when i played guitar i wish i spend more time playing guitar. I spend most of time searcing which guitar is best.

[@BlondieSL]

That software to build screens/pages sure reminds me of the "Editor" for Nextion displays. It sure makes life easier. I use Nextion for 99% of my projects and what's cool, is I can design pages that are similar between projects, save those pages to the network, then just call them up as needed. Of course, I can then edit everything to match the current project. I wonder if this software works with an ESP32 WROOM and any display?? That would be so cool. If not, it's too bad that there's not some software similar to that which would work for an ESP32 WROOM (or other boards) and any display and still allow Arduino IDE coding. I'm not wanting to learn new code for some other board. LOL

[@VolosProjects]

It work with any esp32 board .Thank you.

[@BlondieSL]

@@VolosProjects But is the code going to be Arduino IDE code or some other code?

Now that squareline studio has decided to part ways with lvgl and develop it as independent UI software, you start using it😂

[@deadly_dave]

What about using the ESP32 Cheap Yellow Display Board (ESP32-2432S028R)

[@VolosProjects]

I am not sure CYD is good choice for this. Older esp32 ic and no PSRAM memory.

[@deadly_dave]

That's fair. Nevermind, I have one sitting here that I need to learn to use properly.

I've been enjoying following your channel - because you didn't use SquareLine Studio. It's unsuitable for Open Source projects, so I'm always looking for alternatives. So our roads will split here - I stop subscribing to your channel and will search for somebody else who works with true open source solutions.

[@percramer]

Lvgl stopped the cooperation with Squareline studio. It is better to start learning some of the alternatives

[@MaltWhiskey]

What are those alternatives?

aaand another subscription based app... no thanks...

[@RicardoRibeiro-dorcari]

To which app are you referring ? Lvgl is free

[@lohikarhu734]

Square line studio. It has a fairly limited free version, but, yes, subscriptions. .... Kind of bummed me out, too, but I think that ST has a bunch of graphic support in the last few months.

[@0miker0]

The free version is lets you do everything the paid version does but limits on five screen and fifty controls. This is more than enough for anyone.

[@VolosProjects]

I agreee mike, i never needed paid version. Now you can have 150 widgets in personal licence.

[@MaxSMoke777]

I feel very disappointed in you at this moment. I do want to know more about LVGL... but still disappointed. Your pure code interfaces were inspiring.
