Alternative Controller for HHKB
|
||
|
|
===============================
|
||
|
|
|
||
|
|
Feature
|
||
|
|
-------
|
||
|
|
- Mouse Keys
|
||
|
|
- NKRO on USB
|
||
|
|
- Keymap Layers
|
||
|
|
|
||
|
|
|
||
|
|
Customize Keymap
|
||
|
|
----------------
|
||
|
|
see keymap.c.
|
||
|
|
|
||
|
|
|

|
Build for 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, USB_EXTRA_ENABLE, USB_NKRO_ENABLE
|
||
|
|
3. Build hex file.
|
||
|
|
$ make
|
||
|
|
4. Program MCU.
|
||
|
|
$ make program
|
||
|
|
|
||
|
|
|
||
|
|
Build for 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, USB_EXTRA_ENABLE, USB_NKRO_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.
