With the binding referenced to as uint8_t the keymap would be incorrect if more than 256 positions were in use, going to a uint16_t gives large enough headroom to not have to worry
When building for ZMK Studio, we can use the constant stock keymap
for init of the in-memory keymap, to avoid duplicate flash usage
for the keymap from the devicetree.
* To avoid tons of migration, extra flash writes, etc, we keep
the keymaps and settings using a key position index that's tied
to the stock layout, and at runtime mapping key positions as
needed.
* More fine grained status reporting when saving changes. Needed to we
can notify the client if we've got errors saving settings due to
running out of space, etc.
* Return the max layer name lenght in the keymap payload, for the UI to
leverage.
* Add keymap API for getting/setting a bindings
in keymap layers.
* Add layer move support via intemediary ordering array.
* Add settings storage for keymap changes.
* 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.
Note there was one place where a non-strict prototype was actually being used
with an argument, in `zmk_hog_init`. In this case, the actual argument type was
added instead.
Added BEHAVIOR_DT_DEFINE() and BEHAVIOR_DT_INST_DEFINE(), which work
exactly like the DEVICE_*_DEFINE() macros, except they also register the
device as a behavior by adding a pointer to it to a memory section.
Added zmk_behavior_get_binding(), which works like device_get_binding()
except that it only searches the devices that have been registered as
behaviors. This ensures that behaviors cannot have name collisions with
other devices defined by the SoC, which will be important when we remove
the label property from behaviors so they are given their node names.
As an added benefit, this is faster since it searches a smaller list.
Some basic benchmark code I wrote indicates it takes 30-70% as long,
depending on where the behavior is in the list and whether the name
string is an exact pointer match.
From now on, behaviors should use BEHAVIOR_*_DEFINe() instead of
DEVICE_*_DEFINE(), and any code that looks up a behavior by name should
use zmk_behavior_get_binding() instead of device_get_binding().
Changed the property used to define a layer name for displays from
"label" (which affects other things in Zephyr and is deprecated) to
"display-name". (It cannot be named simply "name", because that has
special meaning in newer versions of the devicetree compiler.)
"label" is still supported as a fallback, so no changes need to be made
to existing keymaps.
Changed all code (except for layer names) which used the label property
to use DEVICE_DT_NAME() instead, which uses the label if set or falls
back to the full node name. This matches how Zephyr determines the node
names used with device_get_binding() and allows us to start removing the
deprecated label property from things.
* Refactor sensor events to include channel data,
necessary for prop split encoders, and avoiding duplicate calls,
to fetch channel data twice, etc.
* More consistent behavior driver API.
* Allow setting triggers per resolution at the behavior level optionally.
* Add new sensor behaviors that either take full bindings
add definition, or accept parameters when bound in the
keymap.
* Remove existing hard-coded key press sensor behavior
and instead leverage new generic sensor behaviors to
achieve the same functionality.

Extended the virtual key position system from combos so that each sensor
also gets a virtual key position. This allows sensor behaviors to use
the behavior queue API.
* 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
* Fire an event w/ layer number, state, and timestamp
when a layer is activated/deactivated.
* Add `zmk_keymap_highest_layer_active()` query.
