vb串口调试软件 源码

VB串口调试软件的源码由VB语言编写，主要用于串口通信的调试和测试。以下是一个示例的代码：

Imports System.IO.Ports

Public Class MainForm

    Dim myPort As New SerialPort()

    Private Sub MainForm_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        ' 配置串口参数
        myPort.BaudRate = 9600
        myPort.Parity = Parity.None
        myPort.StopBits = StopBits.One
        myPort.DataBits = 8
        myPort.Handshake = Handshake.None

        ' 绑定串口数据接收事件
        AddHandler myPort.DataReceived, AddressOf DataReceivedHandler

        ' 打开串口
        Try
            myPort.Open()
        Catch ex As Exception
            MessageBox.Show("串口打开失败: " & ex.Message)
        End Try
    End Sub

    Private Sub btnSend_Click(sender As Object, e As EventArgs) Handles btnSend.Click
        ' 发送数据
        If myPort.IsOpen Then
            myPort.WriteLine(txtSend.Text)
        Else
            MessageBox.Show("串口未打开")
        End If
    End Sub

    Private Sub DataReceivedHandler(ByVal sender As Object, ByVal e As SerialDataReceivedEventArgs)
        ' 接收数据
        Dim sp As SerialPort = TryCast(sender, SerialPort)
        Dim data As String = sp.ReadLine()
        
        ' 在接收文本框中显示数据
        Me.Invoke(Sub() AppendToTextBox(data))
    End Sub

    Private Sub AppendToTextBox(text As String)
        txtReceive.AppendText(text & Environment.NewLine)
    End Sub

    Private Sub MainForm_FormClosing(sender As Object, e As FormClosingEventArgs) Handles MyBase.FormClosing
        ' 关闭串口
        If myPort.IsOpen Then
            myPort.Close()
        End If
    End Sub

End Class

以上代码展示了一个简单的VB串口调试软件的源码。该软件通过配置串口参数，打开串口，并支持发送和接收数据。在接收数据时，将接收到的数据显示在接收文本框中。通过该源码，可以自己编译并定制串口调试软件，以满足特定需求。
