Raspberry Pi Windows IoT Arduino USB通信

Question

I have an Arduino connected to my Raspberry Pi 2 via USB and Windows 10 IOT installed on it. I have made an universal app in Visual Studio and it works on the Pi. Which reference do i need to include so that i can communicate to the Arduino via USB?

Answer 1

This code allows PC to Arduino comms via USB. USB on an Arduino is not really USB. It is serial.

Just connect your Arduino to one of the Raspberry PI's USB ports.

This method will try to find a connected Arduino and write something to the serial port.

    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!");
        }
    }

Add the following capability to your Package.appxmanifest file.

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

Also, take a look at this project for using the Firmata protocol to easily control Arduino from Raspberry PI on Windows IoT Core. I have tried it and it works great!

Answer 3

The problem is the Arduino is not being detected on win iot so serial communication is impossible because no serial port exists from the iot point of view. Any tested solution to detecting Arduino correctly on windows iot would be very appreciated.
