#
# 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

# 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

Lightpad keypad firmware
======================
Korean custom keypad designed by Duck.
*Note that this is not the official firmware*
Supported models
----------------
All pcb options are supported.
Build
-----
Move to this directory then just run `make` like:
$ make -f Makefile.lufa
Bootloader
---------
The PCB is hardwired to run the bootloader if the key at the `top left` position is held down when connecting the keyboard.
It is still possible to use Boot Magic and Command to access the bootloader though.
