According to Arduino's official guide, the Giga R1 works with LVGL. I think it *should* also work with SquareLine & other programs: docs.arduino.cc/tutorials/giga-display-shield/lvgl-guide/

It should work with the ESP32, but please double-check for your exact board or MCU.

Yes, you have many options! Some that come to my mind from the top of my head include using an external EEPROM chip or module (nerdhut.de/2019/01/17/eeprom-arduino/), using an SD card module, sending the data to a server, or storing the values in a hard-coded string in source code (read-only, e.g., config values).

Thanks for your comment! You can find the download link to the project files in the video description. I'm sorry but I can't give you the exported Arduino code, as I uninstalled SquareLine Studio a while ago and I don't want to go through the entire download and installation process.

I'm not entirely sure about that. I think SquareLine and LVGL are mainly intended for use on embedded platforms. However, SquareLine just sent out a newsletter yesterday in which they announced that they want to change the underlying library, so PC support may be a thing soon. Either way, I think there are much better options for making GUIs for PCs. The exact choice depends on your programming language and OS, but Qt would a good point to start for C/C++ and Python.

I'm sorry but I don't have a complete list of devices this setup will work with. However, if you're using an ESP8266, ESP32, or RP2040 then your chances are good. You'll just have to make sure that LVGL supports the display and that you know how to configure the pins in the user config header file.

Hi, thanks for your comment! You#re right, the UI is much slower on the Arduino. I think it's due to how limited the Arduino's processor is. Using a faster device (maybe an ES32 or better) could greatly improve responsiveness. However, that's just a theory, and I haven't tested it. It might also boil down to LVGL. But I think a faster processor will likely improve things

thanks for replying, ill give it a go on an esp32 and let you what I come up with 😊

Hi! Yes, you can. It should work even better with the ESP32 as you should more readily find the necessary configuration files for the MCU. You can use similar commands for handling events (or even the same code if your ESP32 is Arduino-compatible)

Danke dir! Viel Spaß und Erfolg bei deinen Projekten :)

Hi, I always used the most recent version available at that time. I think that must've been 1.3.1 and 1.3.2, respectively.

Thanks for the honest feedback -- I'll see how I can improve the audio in the future!

I had no problem?

​I have just rewatched this on my phone and there was no issue with volume, it seems that only on my laptop and pc is the volume low? I have no issues with any other videos so 🤷‍♂️😅

Hi! This sounds like you'd like to use the LV_EVENT_VALUE_CHANGED event type instead. The CLICK event I used in the video only fires once when you click the slider. You can learn more about both types here: docs.lvgl.io/8/overview/event.html. Please refer to this page if you're looking for an example: docs.lvgl.io/8/widgets/core/slider.html. The first example (simple slider) seems to perfectly match what you're trying to do. I hope this helps! 😊

I also recently uploaded a video where I show the process of linking events to Arduino code: czcams.com/video/PTKjjDPNIdM/video.html

Thanks, I got it working! Really great tutorial series! Incredibly helpful.👍

You can watch the next part here: czcams.com/video/PTKjjDPNIdM/video.html

That is indeed a very valid point! I wanted to make a second part for so long that covers exactly that but I unfortunately never got around to doing it. But from my first experiments it seems relatively easy to accomplish.

Thank you for your kind words -- I'm glad you found the video helpful!

Hi, I'm glad you found the video helpful! Unfortunately, I don't know where you can find a more detailed guide for your board, as finding detailed information on Squareline Studio can get tricky. In addition, many guides quickly become obsolete due to software updates and such. However, the official documentation may contain details for your particular case. Other than that, I suggest asking in some device-specific forums, such as Reddit.

Thanks, I'm glad you found it helpful! :)

Also same thing happened opening your project file

Hi! I'm sorry to hear you're experiencing issues with SquareLine Studio. Unfortunately, I can't assist you with this problem. However, you could try reinstalling the app or writing an email to the SquareLine developers. Unfortunately, the program has quite a few bugs, and this seems like one of them. Either way, good luck with resolving your problem, and feel free to share the solution with us if you have any luck!

Yes, unfortunately. But still a fun program to check out and it has lots of potential when taken care of properly

I too hope to revisit the project at some point in the future!

Hi, I uploaded the project files from the video here: drive.google.com/file/d/1gZ9KizC_inpwgpT0fNuDgBczL9yIJtd3/view?usp=sharing -- I hope you can just download them and open them in SquareLine, but I'm actually not sure whether it will work

@@nerdhut Thanks!I finally have it loading...but i don't know why is super slow the transition and the coordinates are swiped on the Y axis...BHA

I've fixed forcing to set the values from the calibration project. Can you explain me how to manage files between the ui.ino and the other .c files? I'm now a developer, with all in the .ino file is way simpler to do for me :(

@@FrankP83 Hi, I'm not sure whether I got your question right, but the external .c and .h files are just how libraries work. They help keep your custom code files slimmer by extracting common functionality into external files so you don't have to add them to every project. At first, it might look way simpler to have everything in one file but keeping these things separated comes with more benefits in the long run.

@@nerdhut Thanks NerdHut!Last night i've understood how use external vars/methods in .h and .c files!Now i'm trying to go forward!However i've now an issue with the SD initialization...my display isn't parallel, is an ILI9488, and i want to use the SD behind the screen, but if i initialize display and SD, the display turns white and the ESP32s3 start a bootloop ...do you know how to solve it? I can't wait to start exporting all my project from Arduino2 to ESP32s3...

Thank you! I appreciate your kind words :)

Oh, I didn't know that. Thanks for sharing! Is there any undocumented workaround or known fix? I have experienced a similar behavior with some Arduino boards. But with those, you could always force them into bootloader mode. Doing so would typically fix upload problems.

@@nerdhut I searched but it seems complicated and poorly documented. I do not know how to do. It would first be necessary to recover the recognition of the XIAO by the device manager. I think the bootloader or Arduino IDE I use in my case are not robust.

@@michelfrance75 Huh, that's an interesting problem. I might look into these issues myself once I have more time.

They have a fix for this.
