========================
http://github.com/tmk/tmk_keyboard
This is keyboard firmware for AVR USB MCUs or Teensy/Teensy++ 2.0.
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.
http://www.pjrc.com/teensy
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
Functions
---------
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
-----
Compiling sources need AVR GCC, AVR Libc and GNU make.(You can use WinAVR on Windows.)
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)
$ cd <target> (hhkb or macway currently)
$ make
http://winavr.sourceforge.net/
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
-------------
Makefile:
Comment out to disable the option
# USB NKey Rollover
USB_NKRO_ENABLE = yes
<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
# mouse keys
MOUSEKEY_ENABLE = yes
# PS/2 mouse support
PS2_MOUSE_ENABLE = yes
