cLvgl: add template to run lvgl widget demo #270
Conversation
|
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 ? |

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 |
- Update templates.json so that LVGL appears as a choice - Update tasks.json to fetch LVGL from github if needed - Simplify + cleanup CMakeLists.txt - hardcode to /dev/fb0 - Provide default configuration lv_conf.h - Update launch.json so that executable is debugged on the device

Here I think that would be better use the cgroups rules:
# Add device access rights through cgroup...
device_cgroup_rules:
# ... for tty
- "c 4:* rmw"
# ... for /dev/input devices
- "c 13:* rmw"
# ... for /dev/dri devices
- "c 226:* rmw"
- "c 199:* rmw"
# ... for /dev/fb0
- "c 29:* rmw"
and share the /dev:
volumes:
- type: bind
source: /dev
target: /dev

We do not use commontorizon/ images anymore, so here should be torizon/debian-croos-toolchain-${IMAGE_ARCH}:${CROSS_SDK_BASE_TAG}

This was smart, I liked it. I would only add the following:
"runOptions": {
"runOn": "folderOpen"
},so, the user will have the code completion from the beginning.

To have the code completion for the lib I need to add the following:
"${workspaceFolder}/lib/**",
"${workspaceFolder}/src/**",This make sense?

I would drop this one, because as this is using the framebuffer would not be good to mess up with the local desktop /dev/fb0, or there is an easy way to run it local with some "virtual display"?

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! |
Provides a template to run LVGL widget demo.
