无法在Raspberry Pi 2上打开Arduino的串口 [英] Can't open serial port to Arduino on Raspberry Pi 2

问题描述

我为IoT（5/12版本）安装了Windows，并尝试使用Arduino设备打开串行连接。它使用Raspbian很好地连接，但是我遇到了Windows的问题。

我在功能中添加了以下内容：

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

以下代码用于尝试打开端口：

 Log（" GetDeviceSelector .."）; 
 var aqsFilter = SerialDevice.GetDeviceSelector（）; 
 
 Log（"Getting dev infos .."）; 
 var deviceInfos = await DeviceInformation.FindAllAsync（aqsFilter）; 
 Log（" Found" + deviceInfos.Count）; 
 
 if（deviceInfos.Count == 0）
 {
 this.Log（" No serial port found"）; 
返回null; 
} 
 
日志（"获取第一个设备信息..."）; 
 var firstDeviceInfo = deviceInfos.First（）; 
 Log（"Trying device"+ firstDeviceInfo）; 
 
 Log（"Opening serial port .."）; 
返回等待SerialDevice.FromIdAsync（firstDeviceInfo.Id）; 

从SerialDevice.FromIdAsync返回的串口为空，而DeviceInfo正确填写并且看起来不错。有什么我想念的吗？

解决方案

我相信它是SerialDevice类中的一个错误。我有同样的问题，但是来自通用Windows程序。

这是我开始的主题：

I installed Windows for IoT (5/12 build) and am trying to open a serial connection with an Arduino device. It connects fine using Raspbian, but I'm running into problems with Windows.

I added the following to the capabilities:

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

The following code is used to try to open the port:

Log("GetDeviceSelector..");
var aqsFilter = SerialDevice.GetDeviceSelector();

Log("Getting dev infos..");
var deviceInfos = await DeviceInformation.FindAllAsync(aqsFilter);
Log("Found " + deviceInfos.Count);

if(deviceInfos.Count == 0)
{
    this.Log("No serial port found");
    return null;
}

Log("Get first deviceinfo..");
var firstDeviceInfo = deviceInfos.First();
Log("Trying device " + firstDeviceInfo);

Log("Opening serial port..");
return await SerialDevice.FromIdAsync(firstDeviceInfo.Id);

The serial port returned from SerialDevice.FromIdAsync is null while the DeviceInfo is filled in properly and looks good. Is there something I'm missing?

解决方案

I believe its a bug in the SerialDevice Class. I have the same issue but from a Universal Windows Program.

Here's the thread that I started:
