DTS modules (device modules) often have a single source file with an empty `struct Module`.
The module's yaml file now allows a `dts-only` boolean to be set, so the source file becomes optional.
`devicetree.yaml` is renamed everywhere to `module.yaml`
app-module:
- Implement `AppStartContext` to reduce amount of `app_start_` and `app_exec` functions: replace them with `app_start_with_context()`
- Add support for environment variables when starting apps
- Implement support for environment variables for apps
graphics-module:
- Add this new module
- Move font-module code into this module
- Implement pixel_buffer
apps:
- Terminal app: reduce memory usage by only buffering a single row of characters, and try to buffer in IRAM when possible. Implement new pixel_buffer.
- App List: Mark apps as favourite to pin them on top. Use touch or press "x" key.
- App List: Add toolbar button that shows alert dialog with info about using favourites

See PR for details: https://github.com/TactilityProject/Tactility/pull/655
- CL-32 features added:
- Hardware revision detection
- v0.3 and v0.4 keyboard
- v0.4 power supply
- Inlined epd library (was a module) and made changes to the device definition (don't do full update after 5 small updates)
- Statusbar: add support for inverted colors
- e-paper driver improvements and warning fixes
- Implemented gpio_controller_get_level()
- Keyboard support improvements (unicode for tca drivers)
- Added POSIX desktop support for SDK builds, application packaging, and integration testing.
- Added POSIX filesystem partitions and improved application path handling.
- Added simulator support for loading and running applications dynamically.
- Improved simulator task stack handling and display startup reliability.
- Improved simulator display scaling, resizing, high-DPI support, and pointer accuracy.
- Fixed LVGL timers and input polling on POSIX. (fixes simulator with Linux on some Intel graphics platforms)
- Standardized data paths across platforms.
- Logging now works via separate task: this allows apps to write to log without it affecting their stdout (for apps that output text as relevant date for other apps, like the File Selection app)
- Fixes for app stdio
- Standardized keyboard input using Unicode-based key codes across supported devices and the simulator. Keyboards don't emit `LV_KEY_*` anymore.
- Refactored lilygo encoder driver into a reusable GPIO rotary encoder driver (see `Drivers/gpio-encoder-module/`). Added more features to the config file.
- Improved LVGL keyboard device management, including duplicate prevention and reliable reconnects.
- LVGL file mutex now registers with lvgl start/stop
- Improved LVGL startup/shutdown stability and memory allocation reliability.
- Increased simulator LVGL memory capacity and improved USB device-class handling.
Added the newest variant to the tab5, St7121.
Fixed variant detection reliability
Fixed tab5 camera WHO_AM_I failing sometimes
Fixed tab5 keyboard live rotation on boot and after stopping/starting lvgl
shadow_framebuffer records what the panel is currently showing, but both
refresh paths updated it before the refresh was confirmed, so a failed
trigger or a BUSY timeout left it describing content that was never
displayed.
That misdescription compounds: the shadow is sent to the controller as
CMD_DATA_START_OLD, so the per-pixel transitions get computed from an
image the panel never held, and draw_bitmap() diffs against it, so a
region matching a wrong shadow is treated as clean and never repainted.
Both paths now commit only after wait_while_busy() confirms. refresh_full()
also sends new data straight from the render buffer, which drops a
full-framebuffer copy from the path.
Adds sub-GHz radio support to Tactility as a first-class kernel device type, plus a
driver for the Semtech SX1262. Continues the radio work discussed in #342, brought up to
the current kernel driver model (rather than the deprecated tt::hal layer the earlier
prototype targeted).
- Split up `gps-generic-module` into:
- `gps-generic-module` that contains only interfaces/configs/bindings (Apache license)
- `gps-meshtastic-module` that contains an implementation (GPL license)
- Update `LICENSE.md` for changes, but also added clarifications
- Added licenses to directories where they were missing
- Changed license of some test projects from GPL to Apache.
- Replaced device_find_\* usage by device_get_\* variants.
- Removed deprecated device_find_\* functions.
- Improved reliability of Bluetooth scanning, pairing, connection, and HID host lifecycle behavior, including peer auto-connect handling.
- Improved Bluetooth/USB status indicators and clarified “Eject failed” alerts with the affected mount path.
- Added generic GPS/GNSS support with device detection, configuration, and persistent settings.
- Improved device and module lifecycle management.
- Added flexible filesystem locking support for displays and storage.
- Improved display-idle and keyboard backlight handling.
- Updated architecture, driver, module, testing, and licensing documentation.
- Removed old HAL device and related code.
- Created kernel driver for T-Deck Max & Pro display (needs work, doesn't refresh reliably on T-Deck Pro)
- Created T-Deck Pro device implementation (incubating)
