An (Not Portable But Small) Ergonomic Split Keyboard.

Keyboard Maintainer: [hsgw](https://github.com/hsgw/)   [twitter](https://twitter.com/hsgw)  
Hardware Supported: Pro Micro  
Hardware Availability & Repository: [https://github.com/hsgw/ergoinu](https://github.com/hsgw/ergoinu)  

Make example for this keyboard (after setting up your build environment):

    make ergoinu:default

    (or)

    make ergoinu:default_jis


See [build environment setup](https://docs.qmk.fm/build_environment_setup.html) then the [make instructions](https://docs.qmk.fm/make_instructions.html) for more information.

#     automatically to create a 32-bit value in your source code.
#
#     This will be an integer division of F_USB below, as it is sourced by
#     F_USB after it has run through any CPU prescalers. Note that this value
#     does not *change* the processor frequency - it should merely be updated to

#     differ from F_CPU if prescaling is used on the latter, and is required as the
#     raw input clock is fed directly to the PLL sections of the AVR for high speed
#     clock generation for the USB and other AVR subsections. Do NOT tack on a 'UL'
#     at the end, this will be done automatically to create a 32-bit value in your
