Serial Monitor

The Serial Monitor page shows a live log of activity from the Amidala firmware. It's the browser equivalent of a serial terminal — useful for debugging without needing a USB cable.
The monitor displays two types of output:
| Type | Description |
|---|---|
| Outgoing serial | Every string sent out the primary serial port, shown as it is transmitted. Lets you verify that button actions, delimiter substitution, and EOL settings are working correctly. |
| System log | Firmware events: controller connect/disconnect, OTA upload progress, dome state changes, errors. |
Log entries are colour-coded by type (info, warning, error).
- Auto-scroll — the view scrolls to the latest entry automatically. Click the log area to pause auto-scroll; it resumes when you scroll back to the bottom.
- Clear — removes all current entries from the display (does not affect the firmware).
- Filter — type text in the filter box to show only matching lines. Useful when looking for a specific command in a busy log.
- Use the Serial Monitor to verify a newly configured serial string before assigning it to a button. Go to Droid Control, send the string manually, and confirm what appears in the monitor.
- If a button action isn't sending what you expect, check the monitor for the raw output to spot delimiter or EOL issues.
