- Heavily modified, not compatible with McHCK images - Uses 4k of Flash (rather than 3k) - LED turns on when in firmware flash mode - Changed the USB IDs - Added CMake build system - Updated linker script to be closer to what is used for the rest of the projects - Removed a lot of unnecessary code - Added a license header to each file (using the same license as the McHCK had) - Updated the USB Vendor, Product and Serial strings - Using the Kiibohd initialization sequence rather than the McHCK one - Using Kiibohd interrupt vector table and other misc mk20dx setup
