> Kirei is a keyboard library that you feed inputs to (which keys are pressed) and get outputs from (HID reports) ... It's not just a keyboard firmware
In what scenarios might one want to use it?
I agree that the wording is confusing. It's obviously targeting the custom keyboard hobbyists.
But for a sample. Looks like this is what would sit on your custom keyboard and translate your key presses to something the OS you are plugged in to can use. It’s firmware.
Things like the glove80 and Voyager are pretty popular custom keyboards.
