- You can tolggles NKRO feature.
- Keymap customization
- 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.

- 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
- Just type 'make' in a terminal.
- 3. program with Teensy Loader.

- 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)
- 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.
- To define keymap layer switching may needs a bit of your effort at this time.
