🐦 @rjhilgefort's Corne KBD (CRKBD) Layout

My Corne KBD layout is inspired by my Planck Layout, but with some additional features. Namely, this layout has Linux support.

Features

Here's some highlights/features of the layout.

  • Ergonomic symbols layer.
  • Media and Numpad layer.
  • Planck-like extra tri-layer when holding the other two layers.
  • Supports Mac and Linux as 1st class citizens giving each a dedicated base layer and a media layer for each that matches media keys for each OS. The Linux default layer focuses on Ctrl instead of Super and vice versa for Mac. (When you set Linux as your base layer, the Linux media layer is what you shift into. Same for the Mac layer when that's the base)

Building And Flashing

Note, you'll see that most crkbd's recommend a target of avrdude because most kits come with a Pro Micro. I put a Elite-C on mine and thus the target is dfu. You can see this in the rules.mk as the BOOTLOADER configuration.

CLI

make crkbd:rjhilgefort:flash

Docker

util/docker_build.sh crkbd:rjhilgefort:flash
