- RLCD device.properties: DefaultDark (focus UI visible), fontSize 18
(+28% vs 14: small 10->14, default 14->18, large 18->24, icons 16->20/36->48)
- ST7305 driver: honor invertColor config (was ignored), call
esp_lcd_panel_invert_color after init
- DisplayDevice: add supportsInvertColor + set/get, and
supportsMonochromeThreshold/set/get (ST7305 only)
- EspLcdDisplay: implement invert via panelHandle, and mono threshold via
global g_mono_threshold shared with esp_lvgl_port
- DisplaySettings: new fields invertColor (default true to preserve current
inverted look) and monochromeThreshold (default 60 best for DefaultDark per
user testing, range 20-230)
- Lvgl.cpp: apply invert + threshold at boot from settings
- Display app: add Invert colors switch (if supportsInvertColor) + Mono
threshold slider with live preview and persistence
- esp_lvgl_port_disp.c (components override for hash mismatch): fix B/W
conversion
BEFORE: blue >16 only -> crushed colors, no gray handling
AFTER: proper luminance Y=0.299R+0.587G+0.114B with adjustable threshold
(default 60), no Bayer dithering dots. Crisp text on reflective
- Launcher/button/list wrappers reverted to stock DefaultDark (no white
focus hacks) per user request - focus UI now uses default outline which
survives luminance threshold
Verified on waveshare-esp32-s3-rlcd /dev/cu.usbmodem1101:
- Build 2877200 bytes, flash hash verified
- Invert toggle works, threshold slider live (60 best per test)
- Font bump visible, focus UI visible for button navigation
- No dithering dots

- UiDensity moved to lvgl-module
- Deleted tt_hal and tt_hal_gpio (breaks apps, but will fix those right after merging)
- Added I2C 8 bit register operations
- Added device.properties to simulator
- Improved Tab5 hardware init, implement audio
- Add README.md to kernel
**New Features**
* Runtime font accessors and new symbol fonts for text, launcher, statusbar, and shared icons.
* Added font height base setting to device.properties
* Text fonts now have 3 sizes: small, default, large
**Improvements**
* Renamed `UiScale` to `UiDensity`
* Statusbar, toolbar and many UI components now compute heights and spacing from fonts/density.
* SSD1306 initialization sequence refined for more stable startup.
* Multiple image assets replaced by symbol-font rendering.
* Many layout improvements related to density, font scaling and icon scaling
* Updated folder name capitalization for newer style
- Improved UI/UX of various WiFi apps to make it compatible with Cardputer.
- Improved UI/UX of Serial Console to make it compatible with Cardputer.
- Boot app now shows a smaller logo on Cardputer
- CrashDiagnostics app: Use different text if no touch screen is present
### Cardputer:
- Fix keyboard issue with up/down button conflict when selecting switch
- Fix backlight flickering
### UI improvements
- Removed a 3 pixel border that went around the entire desktop environment
- Improved system layout (GuiService)
- Statusbar: improved layout (mainly margin/padding)
- Toolbar: fixed margin/padding of all buttons, fixed alignment of all content
- Improved layout/UI of many apps
### Other
- Update LVGL to 9.3.0 official release (was dev version)
- Implement `UiScale` in `hal::Configuration`: small screens with no touch can now opt for a more optimized experience (e.g. Cardputer, Waveshare 1.47, Waveshare 1.3", etc.)
- Fix for Cardputer UART configuration and added I2C configuration
- Fix for software keyboard bug in Gui
- Removed deprecated fields from `hal::Configuration`
- Updated the simulator devices to use the new HAL config
- add `bool tt::hal::hasDevice(Device::Type)`
- Cleanup of `AppList` app code
- Improve `Gpio` app for small screen devices
- Added various ESP32 GCC wrappers to wrap LVGL functions (with manipulations for small screen devices)
- Moved `Launcher` assets to `assets/` subfolder
- Optimized `Toolbar` for small screen devices
- Stop showing `system/` partition in `FileBrowser` because it's read-only and not very useful. Created `config::SHOW_SYSTEM_PARTITION` to override this behaviour.
- Hide apps when their required hardware isn't available (I2C, UART, PowerDevice)
- Fix for `CYD-2432S032C` DPI setting
