-ADB to USB keyboard converter
-=============================
-This firmware converts ADB keyboard protocol to USB.
-You can use PJRC Teensy for this converter, though, other USB AVR(ATMega32U4, AT90USB64/128 or etc) should work.
-But binary size is about 10KB or more it doesn't fit into 8K flash like ATMega8U2.
-
-Discuss: http://geekhack.org/showwiki.php?title=Island:14290
-
-
-
-README FIRST
-------------
-https://github.com/tmk/tmk_keyboard
-https://github.com/tmk/tmk_keyboard/tree/master/converter/adb_usb
-
-Also check these when you are in trouble.
-
-https://github.com/tmk/tmk_keyboard/wiki
-https://github.com/tmk/tmk_keyboard/labels/NOTE
-
-
-Wiring
-------
-Connect ADB pins to controller just by 3 lines(Vcc, GND, Data). By default Data line uses port PD0.
-
-ADB female socket from the front:
-
-      ,--_--.
-     / o4 3o \      1: DATA
-    | o2   1o |     2: Power SW
-     -  ===  -      3: VCC
-      `-___-'       4: GND
-
-This converter uses AVR's internal pull-up, but it seems to be too weak, in particular when you want to use a long or coiled cable. The external pull-up resistor(1K-10K Ohm) on Data is strongly recommended.(It is almost must!)
-https://github.com/tmk/tmk_keyboard/wiki/FAQ#pull-up-resistor
-
-Pull-up resister:
-
-    Keyboard       Conveter
-                   ,------.
-    5V------+------|VCC   |
-            |      |      |
-           [R]     |      |
-            |      |      |
-    Signal--+------|PD0   |
-                   |      |
-    GND------------|GND   |
-                   `------'
-    R: 1K Ohm resistor
-
-
-Define following macros for ADB connection in config.h if you use other than port PD0.
-
-    ADB_PORT, ADB_PIN, ADB_DDR, ADB_DATA_BIT
-
-
-Build
------
-See doc/build.md. In short,
-
-    $ make clean
-    $ make
-
-You can select keymap(ansi is default) like this:
-
-    $ make KEYMAP=[ansi|iso|hasu]
-
-
-Keymap
-------
-You can change a keymap by editing code of keymap_[ansi|iso|hasu|yours].c.
-How to define the keymap is probably obvious. You can find key symbols in common/keycode.h. And see doc/keymap.md for more detail.
-
-
-Magic command
--------------
-To get help press `h` holding Magic key. Magic key is `Power key`.
-
-
-Locking CapsLock
-----------------
-Many of old ADB keyboards have mechanical push-lock switch for Capslock key and this converter supports the locking Capslock key by default. See README in top directory for more detail about this feature.
-https://github.com/tmk/tmk_keyboard/blob/master/README.md#mechanical-locking-support
-
-Also you may want to remove locking pin from the push-lock switch to use capslock as a normal momentary switch.
-
-
-Notes
------
-Not-extended ADB keyboards have no discrimination between right modifier and left one,
-you will always see left control even if you press right control key.
-Apple Extended Keyboard and Apple Extended Keyboard II can discriminate both side
-modifiers except for GUI key(Windows/Command).
-
-And most ADB keyboard has no diodes in its matrix so they are not NKRO,
-though ADB protocol itself supports it. See protocol/adb.c for more info.
-
-If keyboard has ISO layout you need to use ISO keymap with `make KEYMAP=iso`. With ANSI
-keymap you will suffer from swapped keys problem.
