MSP Protocol in PHP
===================

[](#msp-protocol-in-php)

A PHP implementation of the MSP (serial multiwii) protocol

Usage
-----

[](#usage)

Complete device communication is handled by CommunicationService, which gets a SerialInterface injected.

```
    use Volantus\MSPProtocol\Src\Protocol\CommunicationService;
    use Volantus\MSPProtocol\Src\Protocol\Request\MotorStatus as MotorStatusRequest;
    use Volantus\MSPProtocol\Src\Protocol\Response\MotorStatus as MotorStatusResponse;
    use Volantus\MSPProtocol\Src\Serial\SerialInterface;

    $serialInterface = new SerialInterface('/dev/ttyUSB0', 115200);
    $service = new CommunicationService($serialInterface);

    /** @var MotorStatusResponse $response */
    $response = $service->send(new MotorStatusRequest());

    // Status of the first motor (Value between 1000 and 2000)
    $response->getStatuses()[0];
```

Requests/Response
-----------------

[](#requestsresponse)

> The current request/response implementation set is not complete yet. Especially custom packages from Clean-/Betaflight are missing. Contributors are highly welcome.

All request and responses are encapsulated into objects, which includes interpretation logic about their respective payload structure.

- Request namespace: Volantus\\MSPProtocol\\Src\\Protocol\\Request
- Response namespace: Volantus\\MSPProtocol\\Src\\Protocol\\Response

For a complete list of available (orginal MultiWii) packages please consult the [official documentation](http://www.multiwii.com/wiki/index.php?title=Multiwii_Serial_Protocol).
