Steps 2-7: LDF loading, signal editing, Rx display, connection, BabyLIN backend, scheduler
Step 2 - LDF Loading:
- ldfparser integration (Python) / custom regex parser (C++)
- QTreeWidget with expandable signal rows, merged Value column
- Hex/Dec toggle, FreeFormat schedule entries, auto-reload
- Baud rate auto-detection from LDF
Step 3 - Signal Editing:
- Bit packing/unpacking (signal value ↔ frame bytes)
- ReadOnlyColumnDelegate for per-column editability
- Value clamping to signal width, recursion guard
Step 4 - Rx Panel:
- receive_rx_frame() API with timestamp, signal unpacking
- Change highlighting (yellow), auto-scroll toggle, clear button
- Dashboard view (in-place update per frame_id)
Step 5 - Connection Panel:
- ConnectionManager with state machine (Disconnected/Connecting/Connected/Error)
- Port scanning (pyserial / QSerialPort), connect/disconnect with UI mapping
Step 6 - BabyLIN Backend:
- BabyLinBackend wrapping Lipowsky BabyLIN_library.py DLL
- Mock mode for macOS/CI, device scan, SDF loading, signal access
- Frame callbacks, raw command access
Step 7 - Master Scheduler:
- QTimer-based schedule execution with start/stop/pause
- Frame sent callback with visual highlighting
- Mock Rx simulation, manual send, global rate override
