- Migrated from websockets to aiohttp for unified HTTP/WebSocket server
- Added REST endpoints: /api/pattern, /api/parameters, /api/state, /api/tempo/reset
- Implemented color palette API with 8-slot system and selected colors
- First selected color (index 0) is used as primary RGB for patterns
- All operations now available via simple HTTP requests (no WebSocket needed)
- Added comprehensive documentation: FRONTEND_API.md, COLOR_PALETTE_API.md
- Added test scripts: test_rest_api.sh, test_color_patterns.py
- Updated test/test_control_server.py for new /ws WebSocket path
- Configuration persistence via lighting_config.json
- Pattern parameters (n1-n4, brightness, delay) controllable via API
- WebSocket still available at /ws for legacy support
- Add CONTROL_SERVER_HOST environment variable (default: 0.0.0.0)
- Server now binds to all interfaces by default for external access
- Update .env and .env.example with new host configuration
- Allows UI clients to connect from other machines on the network
- Add python-dotenv support to control_server.py and sound.py
- Load TRANSPORT from environment variable (default: spi)
- Load AUDIO_INPUT_DEVICE from environment variable (default: 7)
- Load all port configurations from environment variables
- Update .env.example with comprehensive configuration options
- Create .env file with sensible defaults for Pi
- Transport, sound device, and network settings now configurable via .env
- Add n4 parameter to control server, LED bar receiver, and test script
- Create segmented_movement pattern with alternating forward/backward movement
- Pattern supports n1 (segment length), n2 (spacing), n3 (forward speed), n4 (backward speed)
- Fix test script to send all messages instead of just the first one
- Add segmented_movement to patterns_needing_params for proper parameter transmission
- Pattern intelligently handles all cases: alternating, forward-only, backward-only, or static
- Implements repeating segments with configurable spacing across LED strip
- Create UI client (src/ui_client.py) with MIDI controller integration
- Create control server (src/control_server.py) with lighting logic
- Implement WebSocket protocol between UI and control server
- Add startup script (start_lighting_controller.py) for all components
- Update Pipfile with new scripts for separated architecture
- Add comprehensive documentation (README_SEPARATED.md)
- Fix LED connection stability with heartbeat mechanism
- Fix UI knob display and button highlighting
- Maintain backward compatibility with existing MIDI mappings
