复盆子pi Windows IoT Arduino USB通信

此代码允许PC通过USB与Arduino通信。 Arduino上的USB不是真正的USB。它是连续的。

http://arduino.cc/playground/Csharp/SerialCommsCSharp .

只需将您的Arduino连接到树莓PI的USB端口之一。

此方法将尝试找到一个连接的Arduino,并向串行端口写入内容。

    private async void ConnectToArduino()
    {
        //Enumerate devices.
        var devices = DeviceInformation.FindAllAsync(SerialDevice.GetDeviceSelector()).AsTask();
        devices.Wait();

        //This will probably get you the connected arduino. (You can also use vendor id to be more accurate).
        var serialDevice = devices.Result.FirstOrDefault(x => x.Name == "USB Serial Device");

        if (serialDevice != null)
        {
            Debug.WriteLine("Found Arduino: " + serialDevice.Name + " " + serialDevice.Id);

            // Create a serial port.
            var serialPort = await SerialDevice.FromIdAsync(serialDevice.Id);
            serialPort.WriteTimeout = TimeSpan.FromMilliseconds(1000);
            serialPort.ReadTimeout = TimeSpan.FromMilliseconds(1000);
            serialPort.BaudRate = 9600;
            serialPort.Parity = SerialParity.None;
            serialPort.StopBits = SerialStopBitCount.One;
            serialPort.DataBits = 8;

            //Write to serial port.
            DataWriter writer = new DataWriter(serialPort.OutputStream);
            writer.WriteString("Hello World!");
            await writer.StoreAsync();

            //Done.
            writer.DetachStream();
        }
        else
        {
            Debug.WriteLine("Arduino not found!");
        }
    }

将以下功能添加到包中。appxmanifest文件。

  <Capabilities>
    <DeviceCapability Name="bluetooth" />
    <DeviceCapability Name="serialcommunication">
      <Device Id="any">
        <Function Type="name:serialPort" />
      </Device>
    </DeviceCapability>
  </Capabilities>

此外,请查看此项目,了解如何使用Firmata协议在Windows IoT Core上轻松控制来自复盆子PI的Arduino。 我试过了,效果很好!

问题是在win-iot上没有检测到Arduino,因此无法进行串行通信,因为从物联网的角度来看,没有串行端口。 任何经过测试的解决方案,可以在windows iot上正确检测Arduino,我们将不胜感激。
