Alternative Controller for HHKB
===============================
Feature
-------
- Mouse Keys
- NKRO on USB(PJRC Tennsy only)
- Keymap Layers
Customize Keymap
----------------
see keymap.c.
Build
=====
PJRC Teensy
-----------
0. Edit matrix.c.
adjust scan code to your pin configuration.(see doc/HHKB.txt for pinouts)
1. Define macros in config_pjrc.h.(Optional)
VENDOR_ID, PRODUCT_ID and string descriptor.
IS_COMMAND
2. Edit Makefile for MCU setting and build options.
MCU, F_CPU
MOUSEKEY_ENABLE, EXTRAKEY_ENABLE, NKRO_ENABLE
3. Build hex file.
$ make -f Makefile.pjrc
4. Program MCU.
$ make -f Makefile.pjrc program
V-USB
-----
0. Edit matrix.c and usbconfig.h.
adjust scan code to your pin configuration.(see doc/HHKB.txt for pinouts)
define macros for V-USB in usbconfig.h.
1. Define macros in config_vusb.h.(Optional)
IS_COMMAND
2. Edit Makefile.vusb for MCU setting and build options.
MCU, F_CPU
MOUSEKEY_ENABLE, EXTRAKEY_ENABLE
3. Build hex file.
$ make -f Makefile.vusb
4. Program MCU.
$ make -f Makefile.vusb program
Using a bootloader to program for convenience is recommended.
Once program this V-USB bootloader at first, you can program MCU without
extra programmer. You should have reset switch to start up as bootloader
mode in this case.
