- 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

- Implement SPI devices in dts files for all devices
- Removed `tt::hal::spi` HAL and its configurations
- Fix for devicetree generator "boolean" support
- Remove unused custom locks in all `DisplayDevice` implementations
- Fixed some bugs with devices
- Updated XPT2046 driver
- Fix for `WifiEsp` deadlock
- Export a lot of new `math.h` symbols with `tt_init.cpp`
- Created `SpiDeviceLock` in `TactilityCore` as a wrapper for kernel SPI locking
- Improved `TactilityKernel` SPI driver.
* **Documentation**
* Added new C coding style guide detailing naming conventions for files, directories, macros, constants, variables, functions, and type definitions with illustrative examples.
* Updated C++ coding style documentation with clarifications on C naming conventions and header directory organization patterns.
* **Refactor**
* Updated header include paths throughout the codebase to use lowercase naming conventions consistently.
* **New Features**
* Time and delay utilities added (ticks, ms, µs); SD card now uses an expansion-header CS pin; HTTP downloads warn when run on the GUI task and yield to avoid blocking.
* **Bug Fixes / Reliability**
* Many hard-crash paths converted to guarded checks to reduce abrupt termination and improve stability.
* **Tests**
* Unit tests added to validate time and delay accuracy.
* **Chores**
* License header and build/macro updates.
- `TT_LOG_*` macros are replaced by `Logger` via `#include<Tactility/Logger.h>`
- Changed default timezone to Europe/Amsterdam
- Fix for logic bug in unPhone hardware
- Fix for init/deinit in DRV2605 driver
- Other fixes
- Removed optimization that broke unPhone (disabled the moving of heap-related functions to flash)
- `DisplayDevice` improvements related `DisplayDriver`
- Replaced incorrect usage of `spiBusHandle` with `spiHostDevice` in all SPI display devices
- Disabled `DisplayDriver` support for RGB displays for now
- Updated `GraphicsDemo` project for the above changes
- TactilityC improvements:
- created `tt_hal_device_find()`
- created `tt_hal_display_*`
- created `tt_hal_touch_*`
- created `tt_lvgl_*`
- export `tt_app_*` calls
- Refactored `TouchDevice`: it can now start/stop LVGL separately, and it has an optional `TouchDriver` interface
- Refactored `DisplayDevice`: it can now start/stop LVGL separately, and it has an optional `DisplayDriver` interface
- Updated all boards and drivers for above changes
- LVGL can now be stopped and (re)started on the fly
- Fixed issues with restarting Gui and Statusbar services
- Refactored `Gui` service to be class and renamed `Gui` to `GuiService`
- Fixed `Statusbar` service: forgot to deregister one of the icons
- Updated `esp_lcd_st7701` to v1.1.3
- `lv_textarea_create()` now automatically registers the hardware keyboard hooks (by wrapping the function)
- Fixed and updated `tactility.py`
- Cleanup of a lot of code
- `BootInitLvglBegin` and `BootInitLvglEnd` are replaced by `LvglStarted` and `LvglStopped`.
- Introduced `tt::service::State` which is accessible via `tt::service::getState()` (and internally via `ServiceInstance`)
- Started replacing `#define TAG` with `constexpr auto TAG = "..";`
