  21 0. Edit matrix.c.
  22     adjust scan code to your pin configuration.(see doc/HHKB.txt for pinouts)
  23 1. Define macros in config_pjrc.h.(Optional)
  24     VENDOR_ID, PRODUCT_ID and string descriptor.
  25     IS_COMMAND
  26 2. Edit Makefile for MCU setting and build options.
  27     MCU, F_CPU
  28     MOUSEKEY_ENABLE, EXTRAKEY_ENABLE, NKRO_ENABLE
  29 3. Build hex file.
  30     $ make -f Makefile.pjrc
  31 4. Program MCU.
  32     $  make -f Makefile.pjrc program

  37 0. Edit matrix.c and usbconfig.h.
  38     adjust scan code to your pin configuration.(see doc/HHKB.txt for pinouts)
  39     define macros for V-USB in usbconfig.h.
  40 1. Define macros in config_vusb.h.(Optional)
  41     IS_COMMAND
  42 2. Edit Makefile.vusb for MCU setting and build options.
  43     MCU, F_CPU
  44     MOUSEKEY_ENABLE, EXTRAKEY_ENABLE
  45 3. Build hex file.
  46     $ make -f Makefile.vusb
  47 4. Program MCU.
  48     $  make -f Makefile.vusb program
  49
  50     Using a bootloader to program for convenience is recommended.
  51     Once program this V-USB bootloader at first, you can program MCU without
  52     extra programmer. You should have reset switch to start up as bootloader
  53     mode in this case.
