[null] Keyboard Firmwares

This repository includes keyboard firmwares built with my modified version of [tmk_core][tmk_core] keyboard library.

The latest source code is available here: http://github.com/tmk/tmk_keyboard

Firmwares

  • jis_110r - a custom 110-key JIS Filco Majestouch keyboard using AT90USB1286 microcontroller.

License

GPLv2 or later. Some protocol files are under Modified BSD License.

Third party libraries like LUFA, PJRC and V-USB have their own license respectively.

Build Firmware and Program Controller

See tmk_core/doc/build.md.

Change your keymap

See tmk_core/doc/keymap.md.

Magic Commands

To see help press Magic + H.

Magic key combination is LShift + RShift in many projects, but Power key on ADB converter. Magic keybind can be vary on each project, check config.h in project directory.

Following commands can be also executed with Magic + key. In console mode Magic keybind is not needed.

----- Command Help -----
c:      enter console mode
d:      toggle debug enable
x:      toggle matrix debug
k:      toggle keyboard debug
m:      toggle mouse debug
v:      print device version & info
t:      print timer count
s:      print status
e:	    print eeprom config
n:	    toggle NKRO
0/F10:  switch to Layer0
1/F1:   switch to Layer1
2/F2:   switch to Layer2
3/F3:   switch to Layer3
4/F4:   switch to Layer4
PScr:   power down/remote wake-up
Caps:   Lock Keyboard(Child Proof)
Paus:   jump to bootloader

Boot Magic Configuration - Virtual DIP Switch

Boot Magic are executed during boot up time. Press Magic key below then plug in keyboard cable. Note that you must use keys of Layer 0 as Magic keys. These settings are stored in EEPROM so that retain your configure over power cycles.

To avoid configuring accidentally additive salt key KC_SPACE also needs to be pressed along with the following configuration keys. The salt key is configurable in config.h. See tmk_core/common/bootmagic.h.

General

  • Skip reading EEPROM to start with default configuration(ESC)
  • Clear configuration stored in EEPROM to reset configuration(Backspace)

Bootloader

  • Kick up Bootloader(B)

Debug

  • Debug enable(D)
  • Debug matrix enable(D+X)
  • Debug keyboard enable(D+K)
  • Debug mouse enable(D+M)

Keymap

  • Swap Control and CapsLock(Left Control)
  • Change CapsLock to Control(Caps Lock)
  • Swap LeftAlt and Gui(Left Alt)
  • Swap RightAlt and Gui(Right Alt)
  • Disable Gui(Left Gui)
  • Swap Grave and Escape(Grave)
  • Swap BackSlash and BackSpace(Back Slash)
  • Enable NKRO on boot(N)

Default Layer

  • Set Default Layer to 0(0)
  • Set Default Layer to 1(1)
  • Set Default Layer to 2(2)
  • Set Default Layer to 3(3)
  • Set Default Layer to 4(4)
  • Set Default Layer to 5(5)
  • Set Default Layer to 6(6)
  • Set Default Layer to 7(7)

Mechanical Locking support

This feature makes it possible for you to use mechanical locking switch for CapsLock, NumLock or ScrollLock. To enable this feature define these macros in config.h and use KC_LCAP, KC_LN UM or KC_LSCR in keymap for locking key instead of normal KC_CAPS, KC_NLCK or KC_SLCK. Res ync option tries to keep switch state consistent with keyboard LED state.

#define LOCKING_SUPPORT_ENABLE
#define LOCKING_RESYNC_ENABLE

Start Your Own Project

  1. Add tmk_core into your repository using git submodule or git subtree.
  2. Copy files from tmk_keybaord or other project similar to yours
  3. Edit those files to support your keyboard.

See these as examples.

Debugging

Use PJRC's hid_listen to see debug messages. You can use xprintf() to display debug info, see tmk_core/common/xprintf.h.

Contribution

  • Report bugs in github Issues.
  • Pull requets are also welcomed.

Coding Style

  • Doesn't use Tab to indent, use 4-spaces instead.
