C＃程序使用COM端口/使用USB串行COM端口與xbee模塊通信

Question

我正在使用usb串行COM端口來發送和接收數據的ac＃程序。 該組件是XBEE模塊，我想要訪問但我寫的代碼不會檢測到我的計算機上的任何串行端口。 任何能幫助我糾正錯誤的人。

using System.IO.Ports;

namespace WindowsFormsApplication3
{
    public partial class Test : Form
    {
        private StringBuilder receivedData = new StringBuilder();

        public Test()
        {
            InitializeComponent();
        }

        private void Test_Load(object sender, EventArgs e)
        {
            Array ports = System.IO.Ports.SerialPort.GetPortNames();
            for (int x = 0; x <= ports.Length; comboBox1.Items.Add(ports.GetValue(x))) ;
            timer1.Start();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            serialPort1.PortName = comboBox1.Text;
            if (!serialPort1.IsOpen)
            {
                serialPort1.Open();
            }
        }

        private void button2_Click(object sender, EventArgs e)
        {
            if (serialPort1.IsOpen)
            {
                serialPort1.Close();
            }
        }

        private void Test_FormClosing(object sender, FormClosingEventArgs e)
        {
            if (serialPort1.IsOpen)
            {
                serialPort1.Close();
            }
        }

        private void button3_Click(object sender, EventArgs e)
        {
            if (serialPort1.IsOpen)
            {
                serialPort1.Write(textBox2.Text + "\n\r");
            }
        }

        private void serialPort1_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
        {
            receivedData.Append(serialPort1.ReadExisting());
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            textBox1.Text = receivedData.ToString();
        }
    }
}

您需要在串行端口上設置正確的參數以匹配設備的設置。 你安裝了XCTU嗎？ 記下“搜索設備”對話框中的設置 - 假設它確實找到了您的設備！

對我來說，我發現我實際上只需要設置波特率：

var serialPort = new SerialPort(portName);
serialPort.BaudRate = 115200;
serialPort.Open();
// win!
