如何发送int从arduino到c＃在PC上

Question

我试图设计一个程序在C＃中，与Arduino板进行通信。这个程序应该接收来自Arduino的整数数据并显示与该值相关的内容。

我唯一需要的是C＃和Arduino Uno中的代码，以便从arduino发送一个值（int）到pc（笔记本电脑集成蓝牙）上的c＃。

问我是否需要我的程序代码。

我已经完成了C＃程序，让我知道它是否正确。

因为我不完全相信你想要的东西对Arduino的侧做，也是因为有许多方法来发送数据，我将解释C＃串口端给你。与Arduino进行通信的最简单方法可能是通过RS-232端口（或者在您的情况下串行端口蓝牙适配器加密狗）。

首先，你要打开一个串口与你的Arduino通过RS-232 Arduino的板应该建立在交流，我已经先行一步，并写了一个简单的程序来读取数据串口下面...

/// <summary> 
/// Read data from Arduino until user presses key. 
/// </summary> 
/// <param name="args">Arguments to the program (we do not take any).</param> 
static void Main(string[] args) 
{ 
    SerialPort port; 

    // first, create a new serial-port 
    port = new SerialPort(); 

    // configure the settings to match the Arduino board 
    // below i've just used some of the most common settings 
    // to get the point across 
    port.BaudRate = 9600; 
    port.DataBits = 8; 
    port.StopBits = StopBits.One; 
    port.Parity = Parity.None; 

    // you'll have to figure out what your actual COM name is 
    // for this example I'll just use COM 11 
    port.PortName = "COM11"; 

    // subscribe to when the data is coming from the port 
    port.DataReceived += Port_DataReceived; 

    // open up communications with the port 
    port.Open(); 

    // continue to receive data until user presses key 
    Console.ReadKey(); 

    // close access to the port when finished 
    port.Close(); 
} 

你需要做的另一件事是创建订户（实际上打印数据的方法）。我已经为你做了下面的...

/// <summary> 
/// Methods for handling the incoming data from Arduino. 
/// </summary> 
/// <param name="sender">The port that's getting data from Arduino.</param> 
/// <param name="e">When the new data comes in.</param> 
private static void Port_DataReceived(object sender, SerialDataReceivedEventArgs e) 
{ 
    SerialPort port; 
    string data = string.Empty; 

    // get a reference to the port that's sending the data 
    port = (SerialPort)sender; 

    // read the data from the port 
    data = port.ReadExisting(); 

    // print Arduino data to the screen 
    Console.WriteLine(data); 
}
