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. | |||
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. | |||
You can customize keymaps easily by editing source code. See keymap.c. | |||
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. | |||
http://img17.imageshack.us/img17/7243/201101181933.jpg | |||
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. | |||
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. | |||

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+Esc: sends Power Event(Power button) | |||
where Magic=(LShift+RShift) or (LControl+RShift) | |||
Fn layer function: | |||
Fn0+(hjkl): Mousekey move(vi cursor like) | |||
Fn0+(yuio): Mouse wheel(left,down,up,right) | |||
Fn0+space: Mouse left button | |||
Fn0+(mnb): Mouse buttons(m=left, n=right, b=middle) | |||
Fn0+(zxc): Media control(Volup, Voldown, Mute) | |||
Fn1+(hjkl): Cursor move(vi cursor like) | |||
Fn1+(nm,.): Cursor move(Home,PageDown,PageUp,End) | |||
where Fn0=;, Fn1=/ | |||
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. | |||

V-USB Support | |||
============= | |||
You can also use this converter on ATmega(168/328) with V-USB instead of Teensy. | |||
The converter on V-USB lacks some features for now: USB NKRO and System/Media control. | |||
To build a firmware use Makefile.vusb instead of Makefile. | |||
