从 arduino 接收和发送数据到 c#，反之亦然

Question

首先我昨天早上开始使用 c#，所以我为潜在的麻木问题道歉。

到目前为止，我编写了以下代码。我能够将数据从 c# 发送到 arduino，这似乎工作正常。现在我想同时通过serial.print从arduino接收数据并将其显示在一个框（ListBox？）中。怎么能把它添加到代码中？

感谢您提供任何意见、提示和想法。

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {

        public Form1()
        {
            InitializeComponent();
            stop.Enabled = false;
            left.Enabled = false;
            right.Enabled = false;
            up.Enabled = false;
            down.Enabled = false;
            string[] ports = SerialPort.GetPortNames();
            comboBox1.Items.AddRange(ports);

        }
        private void Form1_Load(object sender, EventArgs e)
        {


        }
        private void start_Click(object sender, EventArgs e)
        {


            if (comboBox1.SelectedIndex > -1)
            {
                string port = (string)comboBox1.SelectedItem;
                serialPort2.PortName = port; // "port";
                serialPort2.BaudRate = 9600;
                serialPort2.Open();
                if (serialPort2.IsOpen)
                {
                    start.Enabled = false;
                    stop.Enabled = true;
                    left.Enabled = true;
                    right.Enabled = true;
                    up.Enabled = true;
                    down.Enabled = true;
                }
            }
                else
                {
                    MessageBox.Show("Please connect the Arduino and select a Port");
                }

        }
        private void stop_Click(object sender, EventArgs e)
        {
            if (serialPort2.IsOpen)
            {
                serialPort2.Close();
                start.Enabled = true;
                stop.Enabled = false;
                left.Enabled = false;
                right.Enabled = false;
                up.Enabled = false;
                down.Enabled = false;
            }
        }
        private void up_Click(object sender, EventArgs e)
        {

            if (serialPort2.IsOpen)
            {
                serialPort2.WriteLine("1");
            }

        }

        private void left_Click(object sender, EventArgs e)
        {

            if (serialPort2.IsOpen)
            {
                serialPort2.WriteLine("4");
            }

        }

        private void right_Click(object sender, EventArgs e)
        {
            if (serialPort2.IsOpen)
            {
                serialPort2.WriteLine("2");
            }
        }

        private void down_Click(object sender, EventArgs e)
        {
            if (serialPort2.IsOpen)
            {
                serialPort2.WriteLine("3");
            }
        }

使用SolidSoils4Arduino，您可以同时读取和写入串行消息。 Solid.Arduino.IStringProtocol 支持异步读取字符串消息，Solid.Arduino.ArduinoSession 有一个StringReceived 事件，在收到消息时触发。

如果你正在寻找一个轻量级的解决方案，你可以看看 Sharer ：https://github.com/Rufus31415/Sharer

#include <Sharer.h>

// A simple function that sums an integer and a byte and return an integer
int Sum(int a, byte b) {
    return a + b;
}

// A simple function that return a^2
float Square(float a) {
    return a * a;
}

// Init Sharer and declare your function to share
void setup() {
    Sharer.init(115200); // Init Serial communication with 115200 bauds

    // Expose this function to Sharer : int Sum(int a, byte b) 
    Sharer_ShareFunction(int, Sum, int, a, byte, b);

    // Expose this function to Sharer : float Square(float a)
    Sharer_ShareFunction(float, Square, float, a);
}

// Run Sharer engine in the main Loop
void loop() {
    Sharer.run();
}

在您的 C# 应用程序中：

// Connect to Arduino board
var connection = new SharerConnection("COM3", 115200);
connection.Connect();

// Scan all functions shared
connection.RefreshFunctions();

// remote call function on Arduino and wait for the result
var result = connection.Call("Sum", 10, 12);

// Display the result
Console.WriteLine("Status : " + result.Status);
Console.WriteLine("Type : " + result.Type);
Console.WriteLine("Value : " + result.Value);

// Status : OK
// Type : int
// Value : 22

我和你一样，但我用的是电位器。
Pot 模拟输出通过 Serial 发送到 C#；并且 C# 应用程序会读取它。
唯一的区别是我使用了从 Arduino 读取的协议。
您的 Arduino 草图代码取决于您尝试发送和/或接收的内容。 我提供我的例子。我希望这会有所帮助。
