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
|
||||
This firmware converts PS/2 keyboard protocol to USB and for now supports only Scan Code Set 2.
|
||||
|
||||
|
||||
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.)
|
||||
You can tolggles NKRO feature.
|
||||
|
||||
Keymap customization
|
||||
You can customize keymaps easily by editing source code.
|
||||
You can customize keymaps easily by editing source code. See keymap.c.
|
||||
|
||||
|
||||
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.
|
||||
Build Converter
|
||||
---------------
|
||||
0. Connect PS/2 keyboard into Teensy with 4 lines(Vcc, GND, Data, Clock).
|
||||
By default Clock is on PF0 and Data on PF1.
|
||||
You can change this pin configuration by editing config_pjrc.h.
|
||||
In this photo Vcc is yellow, GND is green, Data is red and Clock is black.

|
||||
|
||||
|
||||
Build Frimware
|
||||
--------------
|
||||
1. Edit Makefile for build options and MCU setting.
|
||||
Use 'atmega32u4' for Teensy 2.0 or 'at90usb1286' for Teensy++ 2.0.
|
||||
2. make
|
||||
3. program Teensy.
|
||||
Just type 'make' in a terminal.
|
||||
3. program with Teensy Loader.
|
||||

|
||||
|
||||
|
||||
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.
|
||||
Demonstration of Features
|
||||
-------------------------
|
||||
In default configuration, you can try several keymaps, mousekeys and USB NKRO.
|
||||
Use following magic key combinations to enable some features.
|
||||
|
||||
keymaps and NKRO:
|
||||
Magic+0: Qwerty with mousekeys(default)
|
||||
Magic+1: Qwerty without mousekeys
|
||||
Magic+2: Colemak
|
||||
Magic+3: Dvorak
|
||||
Magic+4: Workman
|
||||
Magic+N: toggles NKRO/6KRO(6KRO by default)
|
||||
Magic+Esc: sends Power Event(Power button)
|
||||
|
||||

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.
