# knx_stack_tpuart

`knx_stack_tpuart` is the Flutter adapter that bridges `knx_stack` to TPUART serial hardware.

## Status

This is the initial implementation slice. The package already exposes runtime compatibility reporting and a raw serial-byte transport. The TPUART state machine, reset flow, ACK handling, and cEMI adaptation will be layered on top of this transport in later slices.

## Platform compatibility

- macOS: supported.
- Linux: supported.
- Windows: supported.
- Android: conditional. The adapter package is present, but Android-specific validation still needs real-device coverage.
- iOS: unsupported.
- Web: unsupported.

## Usage

```dart
import 'package:knx_stack_tpuart/knx_stack_tpuart.dart';

Future<void> main() async {
  final support = KnxTpUartSupport.current();
  final serialSupport = support.supportFor(KnxFeature.tpuartTransport);

  if (!serialSupport.isSupported) {
    throw UnsupportedError(serialSupport.summary);
  }

  final transport = KnxTpUartTransport(portName: '/dev/ttyUSB0');
  await transport.connect();
  await transport.disconnect();
}
```
