Framework’s Via implementation is standard.
The Via electron wrapper app does work. But you do need to load the Framework draft definition. I had some trouble getting the app to detect a keyboard reliably the other day, but no problem today. The draft definitions are found here github.com/FrameworkComputer/qmk_firmware/tree/v0.2.9/keyboards/framework/kle
Download the file(s) that correspond to your module layout.
via_ansi_design.json
via_iso_design.json
via_jis_design.json
via_macropad_design.json
via_numpad_design.json
Which keyboard layout do you need? ANSI, ISO or JIS
ANSI (American) layout. Note the shape of the enter key.
ISO layout. British is shown, but this layout is valid for many languages.
JIS (Japanese) layout.
In the Via electron wrapper app, go to the Design tab (paintbrush icon), click the Load button, then select your draft definition design file. If you don’t have a Design tab, go to Settings (gear icon) to enable it.
If you have multiple modules and multiple design files loaded, as I do in the screenshot, use the Shown Keyboard Definition dropdown to select which is active.
Do note that the Via electron wrapper app is like a self-contained web browser. And it won’t load without internet access.
