Added support for passkey display and passkey confirmation when
pairing. Passkey display is enabled automatically when a display is
enabled. Passkey confirm can be manually enabled if the keyboard has an
Enter key.
Updated the passkey entry code to require all 6 digits have been entered
before confirming and to support backspace to remove a digit.
Added a pairing screen for displays and refactored the display code to
allow for switching between multiple screens. The screens are now
initialized immediately instead of on the display work queue, because
widgets will read state from other files when they are initialized, and
this can only be done safely from the system queue. Blank on idle and
theme initialization are pulled out to separate files to simplify the
main file.
The pairing screen supports all three passkey modes:
- Passkey display just shows the passkey.
- Passkey confirm shows the passkey and an icon indicating that you
must press Enter to confirm.
- Passkey entry shows the current passkey entry state and shows an icon
indicating that you must press Enter to confirm once all 6 digits
have been entered. (If passkey display or confirm are supported, it
seems that Windows will always choose those over passkey entry, but
the pairing screen still supports this in case other OSes work
differently.)
Added configs for normal and large font sizes. The large font is used
for the passkey on the pairing screen on larger displays.
CONFIG_LV_FONT_DEFAULT is no longer used for the normal font size,
because setting a default value for it in display/Kconfig prevented
display shields from picking a more appropriate default.
Add CONFIG_ZMK_DISPLAY_INVERT Kconfig to invert colors
(black-on-white to white-on-black) on monochrome screens.
Currently applies only if CONFIG_LV_USE_THEME_MONO is selected,
which is the default unless user overrides it.
* 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.
* LV_ prefix from new LVGL official Kconfig now used.
* API changes for themes, container object removal, etc.
* Add our own Kconfig and code for theme default small font.
* Remove some hardcoded sizes.
* Add new Kconfig settingsx to allow selecting system or dedicated
work queue for performing UI updates.
* Allow UI updates to not block other system tasks when display is
updating, especially important for e-ink displays.
* 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.
