Hmm, not sure what causes this from the top of my head. You can join my discord server and explain to me exactly what you did. Maybe we can figure it out together :)

@@PhilippThalhammer To be honest, that would be incredible. I'm running into nothing but issues with literally every tutorial I go through. I'm beyond lost & quickly losing steam and wanting to give up on this yet again. When is generally best to be in the discord channel so that people are there?

The discord is still very new, so there are not many people on there generally 😅 I am from germany and thus usually avaliable between 1pm and midnight middle european time. Just write me a message in one of the help-channels and I‘ll see what we can do :)

Did you also not get it to work with this guide? 🤔

@@PhilippThalhammer Yes, but by default I used the latest version of the Arduino Library which uses very different code and will not compile. I could not find any guides for a v9.

What versions are you talking about? Squareline Studio? LVGL?

@@PhilippThalhammer LVGL - When you create a new project in Squareline and select Arduino project, it defaults to V9. So I installed LVGL v9 library in Arduino but there are vast differences between the code for v8 and v9

I see. I also experienced problems when I updated my libraries a couple of months after I did this project.

The pro version is free as well? I have to look into that 😄 Also shipping was 8 days for me with JLC and the cheapest option 🤔

@@PhilippThalhammer My order was on 07. June and today arrived the package from LCSC and the package from JLCPCB is still not here. I hope for delivery by the end of the week.

Thank you :)

? 😄

Glad it helped!

What do you mean by this? 😅 I already get the direction 🤔

Thanks for saying that. It means a lot :) Glad it helped. I absolutely know what you mean. It took me quite a while to figure this out because noone gave a proper explanation 😄

I'm subscribed to your channel keep creating ✌️

Maybe you should take the time and watch it then :) It is in fact not sponsored. About the „misleading title“, I can’t say much. I did not make it with the intend to be misleading 🤷🏻‍♂️ I would also expect that most people wouldn’t think of actually „making“ the PCB by hand, but rather planning them and letting them be manufactured. And regarding the last part about the shipping, I would really recommend watching the video before going into the comments to assume a bunch of stuff. Shipping was under 5$ for me and the PCB arrived within 8 days. You will also come to notice that I do not name any PCB manufacturers.

Feel free to keep polishing that crystal ball of yours while the rest of us enjoy the actual content 👍

Judging from his accent, he's german. So make ("machen") is often used broadly in foreign languages, even if he was referring to actually design(ing). That what happens if you don't use your mother tongue and its certainly not with bad intent.

Thanks, that's true :) Also: Is it that obvious that I am german? xD

@@PhilippThalhammer You aren't being particularly stealthy about that.

Haven't tried it yet. But I would assume yes, as Squareline Studio does support python (as far as I know) and Raspberry PIs can run python scripts just fine. Depending on what you are trying to do, it could be a little overkill to use a PI 5 however 😁 I just started my own discord-community. I would love to hear what you are making over there :)

@@PhilippThalhammer I am planning on using a pi 4 but don’t know what format file to use from SLS?(vsc with sdl or which format from SLS I need to pick for it to work) I am creating a GUI which would incorporate sensors that input values into scrollboxes

The eclipse SDL does support linux (see github.com/lvgl/lv_port_pc_eclipse ). So I guess it would be fine to install rasbian or something similar on your PI and run it there. However, thats just a guess. As I said I haven't tried it before 🤔

I‘m glad it helped! I know exactly what you mean 😄 I spent a lot of time on trying to figure out how everything works, because no one shared all necessary information. I was so frustrated by that, that once I made it work, I decided to do a tutorial on it 😄

There seems to be support for micropython within Squareline Studio, however I am not sure how everything works exactly. I have only tried out Arduino so far 🤔 Glad you like the video :)

I did not define it as a set pin, instead I just read it directly in the loop function at the end :) It is in line 117 where it says „analogRead(25)“

@PhilippThalhammer it makes sense now thank you.

This one does not. There are models with 4 Pins, that include a Vin I belive. When I started playing around with it, I assumed it would be working the same as a Potentiometer and connected 1 pin to ground, one to a GPIO and one to 3.3V. This resulted in me frying my microcontroller 😂

I also had a version that was using interrupts. However, that was causing issues with rest of the code I was using in my project 🤔 I settled for this approach, because its more „general purpose“, I think. Thank you for the comment though. I am also not all-knowing and would love to learn more about the topic :)

You might like to look at the STM32 encoder functions, which use 2 timers to do count and direction, with the ability to "chain" the encoder counter to another timer to get the pulse width of the transitions, to generate speed values...

Sounds interesting 🤔

Did you rename your asset in Squareline studio? This only works if you use the correct name. Maybe it could also be helpful to check out the GitHub repository I linked in the description. I have uploaded the example project there :)

@@PhilippThalhammer No I did not rename the asset. I downloaded your code from the GitHub and compiled it. It gives me this error: exit status 1 Compilation error: 'lv_draw_buf_t' does not name a type; did you mean 'lv_draw_ctx_t'?

Have you set you sketchbook-folder correctly in the Arduino IDE? Other than that I am not really sure what the problem seems to be. It looks like the library is not found correctly, and that normally happens when you dont relocate your sketchbook.

@@PhilippThalhammer OK, I will try this again and report to you. Thank you for the suggestion and help.

Thank you for the encouragement, This means a lot to me! I am planning to do more. Anything specific you would like to see?

Glad to hear that!

1. Das weiß der Aufruf, weil es oben deklariert wird ;) 2. Das Beschriften habe ich beim Aufnehmen vergessen, aber ich habe dafür Text eingeblendet um darauf hinzuweisen (siehe 1:49).

More tutorials? :) Initially I wasn’t going to, but seeing the response to this one kinda changed my mind 😂 I am currently working on one about rotary (ring) encoders, because there seems to be little to no resources about that. Maybe also a showcase on how to use them together with these round displays, as they go great together. Is there anything specific you would like to see? :)

@@PhilippThalhammer if you could also do one with cheaper and readily avaliable oled displays e.g these ili9341 displays it would be great

sorry tft displays

It should be very analogue with other tft displays, if you just follow the steps I outlined with this one. I don't really want to make another video about more or less the same topic 😅 Also the one I am using is about 7€😁 If you have problems feel free to ask though :) Maybe I will also create a discord server for stuff like this in the future 🤔

I haven’t tried doing more advanced stuff with squareline studio, as it does feel really janky and unfinished in my opinion, but I found it to be a shortcut for small projects. Would love to see the results if you try!

@@PhilippThalhammer sadly beside this there is no easy (doh!) way of programing the TFT screen

Yep, thats true… I mean you could go with LVGL from scratch, but I quickly lost motivation when I tried 😅

I think that might be an issue on your side 🤔 I just double checked on my PC and smartphone and its quite loud on both devices. Thank you for the suggestion anyways :)

@@PhilippThalhammerit‘s definitely an issue with this video. I also noticed it right away.

It is a bit quiet on my phone too

Thats wierd. I don’t understand why its not an issue on my devices then 🤔

Do you mean the volume on the video in total is low? Could you check with one of my other videos if the problem persists there as well? If thats no trouble for you of course.

Thank you! I appreciate it :)

Thanks man :) Means a lot.

I use "Things" :)

Thank you man. This means a lot :)
