如何使用串口将信息从 kinect 发送到 arduino？

Question

我一直在摆弄 Kinect SDK 和 arduino，并在网上寻找一种将信息从 Kinect 传递到 arduino 的方法。我只是想传递一些非常简单的信息（即，如果 kinect 识别手势，arduino 会这样做），我发现人们在谈论使用串口来做到这一点。我查看了文档和人们的代码，但我对 C# 很陌生，并不真正了解串行端口的工作原理。我有适用于 Windows v1 的 Kinect，并且正在尝试将信息传递给 botboarduino。如果有人能解释如何设置串口，将不胜感激！

附言。我一直在 Visual Studio 2015 社区为 Kinect 工作，在 Arduino IDE 为 arduino 工作。

Answer 1

有点明显，我知道，但首先使用来自 System.IO.Ports 命名空间的 SerialPort 组件。

Answer 2

示例部分：https://msdn.microsoft.com/en-us/library/system.io.ports.serialport(v=vs.110).aspx MSDN 页面提供了启动串行端口和解析数据所需的所有功能。您当然需要打开您的串行端口，在 Arduino 端设置正确的奇偶校验，以接收您想要发送和处理的所需数据 - 但这样的例子已经足够多了。

Mike 提供的示例应该给出一个大致的布局，但至于在您的程序中设置串行端口，您很可能会遵守9600 8N1。

这是 9600 8N1 的初始串行端口设置示例（这些是针对使用 Boost 库的 C++，但应该清楚您需要设置什么）：

port.set_option(asio::serial_port_base::baud_rate(9600));
port.set_option(asio::serial_port_base::character_size(8));
port.set_option(asio::serial_port_base::flow_control(asio::serial_port_base::flow_control::none));
port.set_option(asio::serial_port_base::parity(asio::serial_port_base::parity::none));
port.set_option(asio::serial_port_base::stop_bits(asio::serial_port_base::stop_bits::one));

当我过去设置它时，我唯一需要确保的是 Arduino 上的波特率与上述设置相匹配，否则其余的似乎是默认设置。不过，我不能保证你的情况。

您需要写入 Arduino 所连接的串口。 Windows 将串口视为文件，所以要写入串口，请使用此类（我使用的是 VS2013，但它应该也适用于 VS2015）：

标头（命名为 SerialClass.h）：

#ifndef SERIALCLASS_H_INCLUDED
#define SERIALCLASS_H_INCLUDED

#define ARDUINO_WAIT_TIME 2000

#include <windows.h>
#include <stdio.h>
#include <stdlib.h>

class Serial
{
private:
    //Serial comm handler
    HANDLE hSerial;
    //Connection status
    bool connected;
    //Get various information about the connection
    COMSTAT status;
    //Keep track of last error
    DWORD errors;

public:
    //Initialize Serial communication with the given COM port
    Serial(char *portName);
    //Close the connection
    ~Serial();
    //Read data in a buffer, if nbChar is greater than the
    //maximum number of bytes available, it will return only the
    //bytes available. The function return -1 when nothing could
    //be read, the number of bytes actually read.
    int ReadData(char *buffer, unsigned int nbChar);
    //Writes data from a buffer through the Serial connection
    //return true on success.
    bool WriteData(char *buffer, unsigned int nbChar);
    //Check if we are actually connected
    bool IsConnected();


};

#endif // SERIALCLASS_H_INCLUDED

CPP 文件（名为 SerialClass.cpp）：

#include "SerialClass.h"
#include<iostream>
Serial::Serial(char *portName)
{
    //We're not yet connected
    this->connected = false;

    //Try to connect to the given port throuh CreateFile
    this->hSerial = CreateFile(portName,
        GENERIC_READ | GENERIC_WRITE,
        0,
        NULL,
        OPEN_EXISTING,
        FILE_ATTRIBUTE_NORMAL,
        NULL);

    //Check if the connection was successfull
    if (this->hSerial == INVALID_HANDLE_VALUE)
    {
        //If not success full display an Error
        if (GetLastError() == ERROR_FILE_NOT_FOUND){

            //Print Error if neccessary
            printf("ERROR: Handle was not attached. Reason: %s not available.\n", portName);

        }
        else if (GetLastError() == ERROR_ACCESS_DENIED)
        {
            printf("It is this!!!!");

        }
        else
        {
            printf("ERROR!!!");
            DWORD error = GetLastError();
            std::cout << error;
        }
    }
    else
    {
        //If connected we try to set the comm parameters
        DCB dcbSerialParams = { 0 };

        //Try to get the current
        if (!GetCommState(this->hSerial, &dcbSerialParams))
        {
            //If impossible, show an error
            printf("failed to get current serial parameters!");
        }
        else
        {
            //Define serial connection parameters for the arduino board
            dcbSerialParams.BaudRate = CBR_9600;
            dcbSerialParams.ByteSize = 8;
            dcbSerialParams.StopBits = ONESTOPBIT;
            dcbSerialParams.Parity = NOPARITY;
            //Setting the DTR to Control_Enable ensures that the Arduino is properly
            //reset upon establishing a connection
            dcbSerialParams.fDtrControl = DTR_CONTROL_ENABLE;

            //Set the parameters and check for their proper application
            if (!SetCommState(hSerial, &dcbSerialParams))
            {
                printf("ALERT: Could not set Serial Port parameters");
            }
            else
            {
                //If everything went fine we're connected
                this->connected = true;
                //Flush any remaining characters in the buffers 
                PurgeComm(this->hSerial, PURGE_RXCLEAR | PURGE_TXCLEAR);
                //We wait 2s as the arduino board will be reseting
                Sleep(ARDUINO_WAIT_TIME);
            }
        }
    }

}

Serial::~Serial()
{
    //Check if we are connected before trying to disconnect
    if (this->connected)
    {
        //We're no longer connected
        this->connected = false;
        //Close the serial handler
        CloseHandle(this->hSerial);
    }
}

int Serial::ReadData(char *buffer, unsigned int nbChar)
{
    //Number of bytes we'll have read
    DWORD bytesRead;
    //Number of bytes we'll really ask to read
    unsigned int toRead;

    //Use the ClearCommError function to get status info on the Serial port
    ClearCommError(this->hSerial, &this->errors, &this->status);

    //Check if there is something to read
    if (this->status.cbInQue>0)
    {
        //If there is we check if there is enough data to read the required number
        //of characters, if not we'll read only the available characters to prevent
        //locking of the application.
        if (this->status.cbInQue>nbChar)
        {
            toRead = nbChar;
        }
        else
        {
            toRead = this->status.cbInQue;
        }

        //Try to read the require number of chars, and return the number of read bytes on success
        if (ReadFile(this->hSerial, buffer, toRead, &bytesRead, NULL) && bytesRead != 0)
        {
            return bytesRead;
        }

    }

    //If nothing has been read, or that an error was detected return -1
    return -1;

}


bool Serial::WriteData(char *buffer, unsigned int nbChar)
{
    DWORD bytesSend;

    //Try to write the buffer on the Serial port
    if (!WriteFile(this->hSerial, (void *)buffer, nbChar, &bytesSend, 0))
    {
        //In case it don't work get comm error and return false
        ClearCommError(this->hSerial, &this->errors, &this->status);

        return false;
    }
    else
        return true;
}

bool Serial::IsConnected()
{
    //Simply return the connection status
    return this->connected;
}

使用示例（将文本写入序列）：

Serial Arduino = Serial("COM3"); //My Arduino is at COM3 - change it for yours!
if (Arduino.IsConnected() == false)  //Checks if it connected
{
    std::cout << "Your Arduino isn't connected!" << std::endl;
    std::cin.ignore();
    return 1;
}
Arduino.WriteData("This is sent data"); //Sends "This is sent data" to the Serial which Arduino is connected to!

Arduino 应该从 Serial 读取数据（使用 Serial 类）。

请注意，您的 Arduino 必须通过 USB 连接到笔记本电脑（不是 Wifi）才能正常工作。 . .
