t.m.k. Keyboard Firmware
========================
This is keyboard firmware for Teensy(AVR USB MCU) and V-USB board.
source code repository:
http://github.com/tmk/tmk_keyboard
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
PS2 to USB: http://geekhack.org/showwiki.php?title=Island:14618
ADB to USB: http://geekhack.org/showwiki.php?title=Island:14290
The project is heavily based on PJRC USB Keyboard/Mouse Example and
owes a debt to preceding keyboard firmware projects.

Limitations
-----------
Files & Directories
-------------------
Target:
hhkb/ keyboard controller for PFU HHKB pro
macway/ keyboard controller for Macway mod
ps2_usb/ PS2 to USB keyboard converter
adb_usb/ ADB to USB keyboard converter
USB Protocol Stack:
pjrc/ PJRC USB stack
vusb/ V-USB USB stack
ps2.[ch] PS/2 protocol
adb.[ch] ADB protocol
Build
-----
To compile needs AVR GCC, AVR Libc and GNU make.
You can use WinAVR on Windows. http://winavr.sourceforge.net/
$ cd <target>
$ 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
EXTRAKEY_ENABLE = yes # Enhanced feature for Windows(Audio control and System control)
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 <COMMAND> + H to debug menu.
(see config.h for <COMMAND> key combination.)
Pressing any 3 keys when connected enables debug output.
Pressing any 4 keys when connected makes bootloader comes up.
