  16 Build for Teensy
  17 ----------------
  18 0. Edit matrix.c.
  19     adjust scan code to your pin configuration.(see doc/HHKB.txt for pinouts)
  20 1. Define macros in config_pjrc.h.(Optional)
  21     VENDOR_ID, PRODUCT_ID and string descriptor.
  22     IS_COMMAND
  23 2. Edit Makefile for MCU setting and build options.
  24     MCU, F_CPU
  25     MOUSEKEY_ENABLE, USB_EXTRA_ENABLE, USB_NKRO_ENABLE
  26 3. Build hex file.
  27     $ make
  28 4. Program MCU.
  29     $  make program

  32 Build for V-USB
  33 ---------------
  34 0. Edit matrix.c and usbconfig.h.
  35     adjust scan code to your pin configuration.(see doc/HHKB.txt for pinouts)
  36     define macros for V-USB in usbconfig.h.
  37 1. Define macros in config_vusb.h.(Optional)
  38     IS_COMMAND
  39 2. Edit Makefile.vusb for MCU setting and build options.
  40     MCU, F_CPU
  41     MOUSEKEY_ENABLE, USB_EXTRA_ENABLE, USB_NKRO_ENABLE
  42 3. Build hex file.
  43     $ make -f Makefile.vusb
  44 4. Program MCU.
  45     $  make -f Makefile.vusb program
  46
  47     Using a bootloader to program for convenience is recommended.
  48     Once program this V-USB bootloader at first, you can program MCU without
  49     extra programmer. You should have reset switch to start up as bootloader
  50     mode in this case.
