- Add RGBW LED type support alongside existing RGB LEDs
- Implement 4-channel RGBW data transmission (R,G,B,W bytes)
- Add RGBW visual preview with half-color, half-white gradient display
- Fix RGB color calibration bug in publisher (was not being applied)
- Create comprehensive hardware communication protocol documentation
- Support mixed RGB/RGBW LED strips on same display
- Add W channel color temperature adjustment in white balance page
- Hardware acts as simple UDP-to-WS2812 bridge without type distinction
- Fix integer underflow panic in LED color publisher by adding bounds checking
- Reduce screenshot capture frequency from 15 FPS to 5 FPS for better CPU performance
- Reduce WebSocket force-send frequency from 200ms to 500ms
- Fix WebSocket resource leak by properly cleaning up streams when connections end
- Add proper stream lifecycle management with is_running flag checks
- Ensure background tasks exit when streams are stopped
This resolves the issue where CPU usage remained above 100% after visiting
the LED strip configuration page, even when navigating to other pages.
- Add comprehensive expandable help section in normal mode with detailed instructions
- Include usage recommendations, adjustment tips, and comparison methods
- Add simplified tooltip in fullscreen mode for quick reference
- Improve user guidance for LED strip color calibration process
- Maintain dual-mode functionality (normal/fullscreen) with appropriate help content
- Reduced image processing time from 7-8 seconds to 340-420ms (15-20x improvement)
- Optimized BGRA->RGBA conversion with unsafe pointer operations and batch processing
- Changed image resize filter from Lanczos3 to Nearest for maximum speed
- Reduced target resolution from 400x225 to 320x180 for better performance
- Reduced JPEG quality from 75 to 50 for faster compression
- Fixed force-send mechanism timing from 500ms to 200ms intervals
- Improved frame rate from 0 FPS to ~2.5 FPS
- Cleaned up extensive debug logging and performance instrumentation
- Removed unused imports and variables to reduce compiler warnings
- Add LED strip visualization around display previews
- Show real-time color status for each LED pixel
- Support multi-display LED strip configurations
- Use elegant 16px thin LED strip design
- Real-time LED color sync via WebSocket
- Responsive layout with display scaling support
- Fix LED color publisher: uncomment display_colors_tx.send() to enable LED color events
- Replace rust_swift_screencapture with screen-capture-kit for better macOS compatibility
- Add bounds checking in LED color processing to prevent array index errors
- Update screenshot manager to use CGDisplay as fallback implementation
- Fix frontend screenshot URL protocol to use ambient-light://
- Add debug logging for LED color events in frontend
- Remove debug logs that were added for troubleshooting
- Update dependencies and remove CMake-dependent paho-mqtt temporarily
This resolves the issue where LED color events were not being sent to the frontend,
enabling real-time LED color visualization in the UI.
