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.





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.
