"""Tkinter GUI monitor for PyBusMonitor1553.
|
|
|
|
Minimal GUI with:
|
|
- Treeview showing registered messages (label, CW.raw, size)
|
|
- Text log for raw sent/received events
|
|
- Buttons: `Initialize`, `Start`, `Stop`, `Refresh`
|
|
|
|
This scaffold calls `pybusmonitor1553.core.connection_manager` for init/start/stop.
|
|
All code, comments and UI text are English.
