* Move to local/stack allocated event API that doesn't require
dynamic allocation/freeing.
* Disable heap, we no longer use alloc/free unless using LVGL.
* Tons of refactors all over to account for the new event approach.
Before this change, if a matrix position was not present in the transform,
various incorrect behaviors would happen:
1) In some cases out-of-bounds accesses:
Note that the size of the`transform[]` array does not necessarily match
the size of the matrix. So for example if key position
(ZMK_MATRIX_COLS-1, ZMK_MATRIX_ROWS-1) is not present in the transform,
but ends up being pressed, then the array will be accessed beyond its
size, and any data could be returned.
2) In other cases the 0th position in the keymap will be used because
the `transform[]` array is initialized to all zeros.
* Move away from DT_LABEL.
* Move to DEVICE_DT_GET for non-behavior device access.
* Move various drivers to `gpio_spec_dt` and `DT` related macros.
* Remove mcp23017 while at it, since better upstream driver is
available.
* GATT characteristic allowing passng data + behavior
label to invoke the behavior on the peripheral side.
* Behaviors have a locality setting to specify where they run.
* Build reset/power/RGB on peripheral.
* Make it easier to use *just* event payloads by defining the data,
and then having event manager macros generate "wrapper structs"
* Improve is_*/cast_* APIs to hide details of full event struct.
* Create `zmk_event_t` typedef to pass to event handlers.
* Bring event names inline w/ consistent `zmk_` prefix.
Aligns *.h and *.c to underscore naming convention.
These were kept (with warnings) for backwards compatibility with external boards/shields:
- kscan-mock.h
- matrix-transform.h
They should be removed in the future.
PR: #523
* Add timestamps to position events and behaviors.
- Take original event timestamps into consideration so nested tap-holds have proper timing.
- Add position and timestamp to keycode state changed event so the one-shot behavior can properly identify other keypresses and timings.
- Add timestamp to position events received from peripheral
* reduce number of arguments to behaviors
* Add initial event manager implementation,
roughly mimicking Nordic's API.
* Add `position_state_changed` and
`keycode_state_changed` events.
* Hook up HID and keymap to new events
instead of using behaviour global event
crazy.
