- PS/2 to USB keyboard converter
- ==============================
-
- This firmware converts PS/2 keyboard protocol to USB.
-
-
- Demostration build
- ------------------
- In this demo build, you can try several layouts,
- mouse keys and USB NKRO.
-
- Special keys:
- Magic+0: Qwerty with mouse keys(default)
- Magic+1: Qwerty
- Magic+2: Colemak
- Magic+3: Dvorak
- Magic+4: Workman
- Magic+N: toggles NKRO/6KRO(6KRO by default)
- Magic+Esc: sends Power Event
- where Magic=(LShift+RShift) or (LControl+RShift)
-
- Keybinds:
- Fn0+(hjkl): Mouse key move(vi cursor)
- Fn0+(yuio): Mouse wheel(left,down,up,right)
- Fn0+space: Mouse button1
- Fn0+(mnb): Mouse buttons(1,2,3)
- Fn0+(zxc): Media control(Volup, Voldown, Mute)
- Fn1+(hjkl): Cursor move(vi cursor)
- Fn1+(nm,.): Cursor move(Home,PageDown,PageUp,End)
-
- Fn2+(esdf): Mouse key move(invert T cursor)
- Fn2+(qwrt): Mouse wheel(left,down,up,right)
- Fn2+space: Mouse button1
- Fn2+(,./): Media control(Volup, Voldown, Mute)
- where Fn0=;, Fn1=/, Fn2=a
-
-
- Features
- --------
- Mouse keys
- You can emulates mouse move and button click using keyboard.
- System/Media control
- You can sends Power event, Volume down/up and Mute.
- USB NKRO(actually 120KRO+8Modifiers)
- You can tolggles NKRO/6KRO.(Not tested on Mac.)
- Keymap customization
- You can customize keymaps easily by editing source code.
-
-
- Build for Teensy
- ----------------
- 0. Connect PS/2 keyboard to Teensy by 4 lines(Vcc, GND, Data, Clock).
- 1. Define following macros for PS/2 connection in config_pjrc.h:
- PS2_DATA_PORT
- PS2_DATA_PIN
- PS2_DATA_DDR
- PS2_DATA_BIT
- PS2_CLOCK_PORT
- PS2_CLOCK_PIN
- PS2_CLOCK_DDR
- PS2_CLOCK_BIT
- 2. Edit Makefile for build options and MCU setting.
- 2. make
- 3. program Teensy.
- http://www.pjrc.com/teensy/loader.html
-
-
- Build for V-USB
- ---------------
- 0. Build V-USB controller board and connect PS/2 keyboard.
- 1. Define macros in config_vusb.h if needed.
- 2. Edit Makefile.vusb for build options and MCU setting.
- 3. make -f Makefile.vusb
- 4. program your V-USB controller.

- Keymap
- ------
- You can change a keymap by editing code of keymap.c like following.
- How to define the keymap is probably obvious. You can find key
- symbols in usb_keycodes.h.
- If you want to define more than one keymap, see hhkb/keymap.c and
- macway/keymap.c as examples. To define keymap(layer) switching may
- needs a bit of your effort at this time.
