### Advanced Setup
For production use, you can set up the web interface as a systemd service:
1. **Create a service file:**
```bash
sudo nano /etc/systemd/system/ledmatrix-web.service
```
2. **Add the following content:**
```ini
[Unit]
Description=LED Matrix Web Interface V2
After=network.target
[Service]
Type=simple
User=pi
WorkingDirectory=/home/pi/LEDMatrix
ExecStart=/usr/bin/python3 /home/pi/LEDMatrix/start_web_v2.py
Restart=always
RestartSec=10
[Install]
WantedBy=multi-user.target
```
3. **Enable and start the service:**
```bash
sudo systemctl enable ledmatrix-web
sudo systemctl start ledmatrix-web
```
## Usage Guide
### Getting Started
1. **Connect to your display:**
- The interface will automatically attempt to connect to your LED matrix
- Check the connection status indicator in the bottom-right corner
2. **Monitor your system:**
- View real-time system stats in the header
- Check service status and performance metrics in the Overview tab
3. **Control your display:**
- Use the Start/Stop buttons to control display operation
- Take screenshots for documentation or troubleshooting
### Using the Display Editor
1. **Enter Editor Mode:**
- Click the "Enter Editor" button to pause normal display operation
- The display will switch to editor mode, allowing you to customize layouts
2. **Add Elements:**
- Drag elements from the palette onto the display preview
- Elements will appear where you drop them
- Click on elements to select and edit their properties
3. **Customize Elements:**
- Use the Properties panel to adjust position, color, text, and other settings
- Changes are reflected in real-time on the display
4. **Save Your Layout:**
- Click "Save Layout" to store your custom design
- Layouts are saved locally and can be reloaded later
### Element Types
#### Text Elements
- **Static text:** Display fixed text with custom positioning and colors
- **Data-driven text:** Display dynamic data using template variables
- **Clock elements:** Show current time with customizable formats
#### Visual Elements
- **Weather icons:** Display weather conditions with various icon styles
- **Rectangles:** Create borders, backgrounds, or decorative elements
- **Lines:** Add separators or decorative lines
#### Advanced Elements
- **Data text:** Connect to live data sources (weather, stocks, etc.)
- **Template text:** Use variables like `{weather.temperature}` in text
### Configuration Management
#### Display Settings
- **Brightness:** Adjust LED brightness (1-100%)
- **Schedule:** Set automatic on/off times
- **Hardware settings:** Configure matrix dimensions and timing
#### System Management
- **Service control:** Start, stop, or restart the LED matrix service
- **System updates:** Pull latest code from git repository
- **Log viewing:** Access system logs for troubleshooting
- **System reboot:** Safely restart the system
## API Reference
The web interface provides a REST API for programmatic control:
### Display Control
- `POST /api/display/start` - Start the display
- `POST /api/display/stop` - Stop the display
- `GET /api/display/current` - Get current display image
### Editor Mode
- `POST /api/editor/toggle` - Toggle editor mode
- `POST /api/editor/preview` - Update preview with layout
### Configuration
- `POST /api/config/save` - Save configuration changes
- `GET /api/system/status` - Get system status
### System Actions
- `POST /api/system/action` - Execute system actions
## Customization
### Creating Custom Layouts
Layouts are stored as JSON files with the following structure:
```json
{
"layout_name": {
"elements": [
{
"type": "text",
"x": 10,
"y": 10,
"properties": {
"text": "Hello World",
"color": [255, 255, 255],
"font_size": "normal"
}
}
],
"description": "Layout description",
"created": "2024-01-01T00:00:00",
"modified": "2024-01-01T00:00:00"
}
}
```
### Adding Custom Element Types
You can extend the layout manager to support custom element types:
1. **Add the element type to the palette** in `templates/index_v2.html`
2. **Implement the rendering logic** in `src/layout_manager.py`
3. **Update the properties panel** to support element-specific settings
### Theming
The interface uses CSS custom properties for easy theming. Modify the `:root` section in the HTML template to change colors:
```css
:root {
--primary-color: #2c3e50;
--secondary-color: #3498db;
--accent-color: #e74c3c;
/* ... more color variables */
}
```
## Troubleshooting
### Common Issues
1. **Connection Failed:**
- Check that the LED matrix hardware is properly connected
- Verify that the display service is running
- Check firewall settings on port 5001
2. **Editor Mode Not Working:**
- Ensure you have proper permissions to control the display
- Check that the display manager is properly initialized
- Review logs for error messages
3. **Performance Issues:**
- Monitor system resources in the Overview tab
- Reduce display update frequency if needed
- Check for memory leaks in long-running sessions
### Getting Help
1. **Check the logs:**
- Use the "View Logs" button in the System tab
- Check `/tmp/web_interface_v2.log` for detailed error messages
2. **System status:**
- Monitor the system stats for resource usage
- Check service status indicators
3. **Debug mode:**
- Set `debug=True` in `web_interface_v2.py` for detailed error messages
- Use browser developer tools to check for JavaScript errors
## Performance Considerations
### Raspberry Pi Optimization
The interface is designed to be lightweight and efficient for Raspberry Pi:
- **Minimal resource usage:** Uses efficient WebSocket connections
- **Optimized image processing:** Scales images appropriately for web display
- **Caching:** Reduces unnecessary API calls and processing
- **Background processing:** Offloads heavy operations to background threads
### Network Optimization
- **Compressed data transfer:** Uses efficient binary protocols where possible
- **Selective updates:** Only sends changed data to reduce bandwidth
- **Connection management:** Automatic reconnection on network issues
## Security Considerations
- **Local network only:** Interface is designed for local network access
- **Sudo permissions:** Some system operations require sudo access
- **File permissions:** Ensure proper permissions on configuration files
- **Firewall:** Consider firewall rules for port 5001
## Future Enhancements
Planned features for future releases:
- **Multi-user support** with role-based permissions
- **Plugin system** for custom element types
- **Animation support** for dynamic layouts
- **Mobile app** companion
- **Cloud sync** for layout sharing
- **Advanced scheduling** with conditional logic
- **Integration APIs** for smart home systems
