Refactored Bluetooth support to make adding new Bluetooth modules
easier in the future.
* Remove `OUT_BLE` key from QMK's keymap. `OUT_BT` is all we need now
as there's no difference anymore.
* Made BLUETOOTH_ENABLE build option legacy as not to break existing
keymaps (Falls back to existing EZ Key support if on)
* Removed `ADAFRUIT_BLE_ENABLE` build option
* Created new build option `BLUETOOTH` with module option (Currently
`AdafruitEZKey` & `AdafruitBLE`)
* Moved all LUFA bluetooth key/mouse events under `BLUETOOTH_ENABLE`
ifdef with selected modules output.
The previous two options were COL2ROW, ROW2COL; this adds CUSTOM_MATRIX
to disable the built-in matrix scanning code.
Most notably, this obviates the need to set MATRIX_ROW_PINS or
MATRIX_COL_PINS.
since the keycode for a tap dance process gets process only after the
TAPPING_TERM timeout, you really only have ONESHOT_TIMEOUT -
TAPPING_TERM time to tap or double tap on the key. This fix save the
oneshot_mods into the action.state structure and applies the mods with
the keycode when it's registered. It also unregisters the mod when the
the tap dance process gets reset.
Scenario:
Locking the KC_LSHIFT, and then using a tap dance key that registers a
S(KC_9) will unregister the KC_LSHIFT.
The tap dance or any keycode that is registered should not have the
side effect of cancelling a locked moditifier. We should be using a
similar logic as the TMK codes in tmk_core/comman/action.c:158.
A macro key can now be easily set to act as a modifier on hold, and
press a shifted key when tapped. Or to switch layers when held, and
again press a shifted key when tapped.
Various other helper defines have been created which send macros when
the key is pressed, released and tapped, cleaning up the
action_get_macro function inside keymap definitions.
The layer switching macros require a GCC extension - 'compound
statements enclosed within parentheses'. The use of this extension is
already present within the macro subsystem of this project, so its use
in this commit should not cause any additional issues.
MACRO_NONE had to be cast to a (macro_t*) to suppress compiler
warnings within some tapping macros.
