t.m.k. Keyboard Firmware
========================
http://github.com/tmk/tmk_keyboard

This is keyboard firmware for AVR USB MCUs or Teensy/Teensy++.
http://www.pjrc.com/teensy

The project is heavily based on PJRC USB Keyboard/Mouse Example and
owes a debt to preceding keyboard firmware projects.

This firmware is used in following projects:
HHKB mod:   http://geekhack.org/showwiki.php?title=Island:12047
Macway mod: http://geekhack.org/showwiki.php?title=Island:11930


Features
--------
Mouse key
    control mouse cursor from keyboard.
System Control Key
    Power Down, Sleep, Wake Up & USB Remote Wake up
Media Control Key
    Volume Down/Up, Mute
USB NKRO
    send 120 keys(+ 8 modifiers) at most simultaneously.
PS/2 mouse support
    integrate PS/2 mouse(TrackPoint) into keyboard as composite device.


Limitations
-----------


Build
-----
To compile needs AVR GCC, AVR Libc and GNU make.
You can use WinAVR on Windows.  http://winavr.sourceforge.net/

$ cd <target> (hhkb or macway currently)
$ make

The firmware will be compiled as a file tmk_<target>.hex.


Build your own firmware
-----------------------
Copying exsistent target(macway) is easy way.
1. Copy contens of macway/ to your own target directory.
2. Edit Makefile. See next section.
3. Edit config.h. See next section.
4. Edit matrix.c. You will need to fix followings at least.
     matrix_init()
     matrix_scan()
     read_col()
     unselect_rows()
     select_row()
5. Edit keymap.c. NOTE: It is not final design and a bit messy.
   You will need to fix followings at least.
     KEYMAP
     fn_layer[]
     fn_keycode[]
     keymaps[]
6. Build.

If you have a build error like following, comment out "--relax" option in Makefile.common.
    (.vectors+0x30): relocation truncated to fit: R_AVR_13_PCREL against symbol `__vector_12'


Build Options
-------------
<target>/Makefile:
1. Set target name for your firmware.
     TARGET = tmk_<target>
2. Choose a MCU and its frequency.
     MCU = atmega32u4       # Teensy 2.0
     #MCU = at90usb1286      # Teensy++ 2.0
     F_CPU = 16000000
3. Choose optional modules as needed. Comment out to disable optional modules.
     MOUSEKEY_ENABLE = yes	# Mouse keys
     PS2_MOUSE_ENABLE = yes	# PS/2 mouse(TrackPoint) support
     USB_EXTRA_ENABLE = yes	# Enhanced feature for Windows(Audio control and System control)
     USB_NKRO_ENABLE = yes	# USB Nkey Rollover

<target>/config.h:
1. USB vendor/product ID and device description
     #define VENDOR_ID       0xFEED
     #define PRODUCT_ID      0xBEEF
     /* device description */
     #define MANUFACTURER    t.m.k.
     #define PRODUCT         Macway mod
     #define DESCRIPTION     t.m.k. keyboard firmware for Macway mod
2. Keyboard matrix configuration
     #define MATRIX_ROWS 8
     #define MATRIX_COLS 8
     #define MATRIX_HAS_GHOST
3. Mouse keys configuration if needed.
4. PS/2 mouse configuration if needed.


Debuging & Rescue
-----------------
Use PJRC's hid_listen.exe to see debug messages.
Press right Control + Shift + Alt + GUI + H to debug menu. 

Pressing any 3 keys when connected enables debug output.
Pressing any 4 keys when connected makes bootloader comes up.
