Qml.Net VS frt

Or QML.Net

QML.Net seems to be the best of the bunch for this right now.

It looks like there are actually qml bindings for mono but not sure how active they are developed...still probably the closest you get if you want to stuck with .net

You might try QML.Net. That's a Qt library for C#, which (in theory) should play nice with LXDE in Raspbian. In theory. YMMV.

BLUF: Does anyone have some experience with qmlnet?

Instead, write your project as if you're targeting Linux. If you need a GUI, use QML.Net. It's a C# binding for QT. To access USB, try LibUsbDotNet.

Since you're specifically looking for a replacement for a desktop UI framework, I would look into QML.Net. It works across Windows and Linux (and even MacOS X) by using the Qt framework under the hood.

And there's Qml.Net if qml/qt is more what you want.

another option is to use godot and use a this to target arm cpus https://github.com/efornara/frt

To point you in a direction, Efornara made FRT which was originally meant for Raspberry Pis, but can basically run on any linux arm device now. You can download the binaries and try that, the link is in the description, but you can also build your own templates if you know how to and understand using Docker.

I made a quick test project with a scrolling news ticker and clock. I've exported it with both "the" unofficial Godot Engine for the Raspberry Pi and FRT templates. Both have a similar result: when Godot is scalled to full screen, the frame rate for this controls-only (2D) project is < 20 FPS.

Godot works well on Raspberry pi 4 and other OPENGL ES-supported ARM-devices thanks to Godot FRT export-templates. Check here: https://github.com/efornara/frt I've have tested on a RG351V-handheld. See video here: https://twitter.com/NilskiLabs/status/1593590541622681602?s=20 This is Godot 3.5.2, but support for Godot 4.0 is currently in experimental-phase

FRT by efornara is the repository that explains how the bins are compiled. He also has some compiled bins that you can download and try instead of mine.

You can make godot games and run them on the raspberry pi just fine! At least 2D is working very well and 3D is also working but not feature-complete. Take a look at https://github.com/efornara/frt if you want to run godot games on the pi. I am currently working on a simple 2D RTS specifically made for the Pi Zero 2 and the performance is really good so far. :)

Is this it? And yes, I forgot about TIC-80! I haven't tried that one at all, but it looks very cool.

There are still pending issues, but the basics are there. See: https://github.com/efornara/frt/issues/39

I'm using the Godot game engine mainly. To compile for the RG351, I'm using this export template: https://github.com/efornara/frt
