- 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.
