cLvgl: add template to run lvgl widget demo

[EDGEMTech-GabrielC]

Provides a template to run LVGL widget demo.

Please I have a question. Right now, the template is almost ready. The only last problem I have is that I must embed in a way LVGL repository. I don't think it is a good idea to embed it in the repository and I'd like to know the best way to get this library available to build the application. Any idea ?

[andreriesco]

Hello @EDGEMTech-GabrielC, one way you could do this is by adding a script that downloads/prepares this repo in the workspace, and than add it's path on the installDepsScrips of the .conf/deps.json file, similar to what is done here in the Mono template

Hey @EDGEMTech-GabrielC I addressed some of the comments above on https://github.com/microhobby/vscode-torizon-templates/tree/add-cLvgl-template , so take a look if these make sense for you, if yes please add the commits on your branch, or give me the access to push it to your repo. Thanks!

[EDGEMTech-GabrielC]

I pushed the changes you mentioned, I also gave you access to the repository if you want to change something else.

Hello @EDGEMTech-GabrielC ,
I tried to run the Local AMD64, which runs the project for local debugging on my host PC, but got the following error:

Error: cannot open framebuffer device: Permission denied

As the template uses framebuffer, should it be able to have local debugging?

[EDGEMTech-GabrielC]

Hello @andreriesco,
As the objective is to provide a plugin to help starting with the boards (many great tutorials are made to run LVGL locally), we decided to remove the Local AMD64. A local debugging should not be available.

@andreriesco this LGTM

Already applied

Actually needs some small fixes and bumps of tags. I will add the commits with the fixes

Could we accept this and then you open a new MR with these small fixes?

[andreriesco]

I think it's better to wait for the Torizon 7 to be merged into dev before merging this one, to make it available on Torizon 7

Ok then.

[kisvegabor]

Can you tell what is the planned release date of Torizon 7?

[andreriesco]

Hello @kisvegabor,
Torizon 7 is already available for the OS part. About the IDE templates for Torizon 7, the PR is currently in development, but the release will be at most next month.

[kisvegabor]

Got it, thank you!

[andreriesco]

Hello @EDGEMTech-GabrielC @kisvegabor ,
I have tested it on Torizon OS 7 with the bumped tags and it's working both for arm32 and arm64.
However, I am having one last issue. I need to something printed on the Debug Console for the automated tests. I tried adding this line printf("Hello Torizon");, but it's not printing it to the Debug Console. Do you guys have an idea on what might be the issue?

[kisvegabor]

Great news!

@EDGEMTech-GabrielC can comment on it in January.

[kisvegabor]

Gabriel just told me that maybe just a \n is missing: printf("Hello Torizon\n"); and/or please try adding fflush(stdout);

[andreriesco]

Nice, now it worked, thanks!

@andreriesco I replaced the LVGL asset. The previous one had a poor quality. Now that the template is completed, is there anything missing from our side to merge it on the main branch ?

[andreriesco]

Nice, thanks @EDGEMTech-GabrielC,
On your side everything is ok. On our side, I have some commits with small fixes and bumps to Torizon 7 on locally on my computer, and then when the Torizon 7 MR is merged into dev I will rebase it and push this commits
