Some time ago I’ve bought a used NCR-80. Everything was just as described and I’ve spent some time getting VIA to work but after some time I’ve managed to upload my custom layout to the keyboard. For some reason, the keyboard has reverted to the default layout or some other layout e.g pressing the enter button types the backslash and the right alt is winkey.
Does anyone have a clue what might have caused the change?
I’m also struggling to find the tutorial that has helped me get VIA to work in the first place.
This is the only one I seem to be able to find and I doesn’t work for me as there’s no “file” button for me thus I cannot upload the json file. I’m using Windows 11
There are two files in question here. The VIA firmware (.hex) file allows VIA to run on the keyboard. The layout (.json) file allows the VIA app to see the layout, which allows you to reassign the key bindings.
First, you’ll need the .hex file which enables VIA to run on the keyboard (don’t know if you have solder or hotswap version). Once the proper firmware is installed, the keyboard should be working with the default key assignments.
The VIA .hex firmware files are available for download from the VIA website at:
Search for NCR-80 shows me the hotswap and solderable versions are there:
Once you download the proper .hex file, you will need to connect the keyboard and flash the file to it with QMK Toolbox Program.
Secondly, in order to reprogram the keyboard you’ll need the .json file mentioned in the instructions loaded into the “draft definition” in the design tab. This is the file that explains to VIA how to program your keyboard. If you click on the link, you’ll get the raw .json file open in google drive. You’ll need to hit the download button and save it to your computer.
What happens when you start VIA? Do you see anything at all or do you just get the “Searching For Devices…” message?
Do you have a “Design” Tab?
If so, clicking on the “Load Definition” button or dragging and dropping the .json file is the same as clicking on “File” in Step 1 of the original istructions (or as I mentioned a few paragraphs up)
You can use the downloaded VIA app or the newest version which is the VIA web app
Hope that helps. Let us know if you are still having trouble.
I find that I have to manually load the .json file if configuring an NCR-80 in VIA.
It’s important to select the right one for your NCR-80, hotswap or soldered.
I get “Seatching for devices…” and enabled the option to see the “Design” tab in settings.
After I’ve bought the keyboard I’ve flashed it with QMK and whatnot and was able to edit the layout freely but out of nowhere It’s changed layouts. Luckily I’ve all the files I have used while setting up the keyboard:
Do you think I need to flash the board all over again or can I just load the json file to the “Draft Definition”? Thanks for the answers!
That’s what I get once i load the definition from json, what is the next step? There’s still no option to configure the layout after loading the definition.
Just reflash it with the VIA hex. You can use the one in that folder or the one from the VIA website. Make you you flash the hotswap version of that’s what you have
I have the solder version of PCB but i don’t know why the instructions told me to do it with hotswap. Maybe things have changed from when I have done it last time
Alright. Thanks for the help. I’ll give you an update once I get round to doing it
