======================================
VB 6.0 是使用MSCOMM元件(我比較常用~因為幾乎用拉的省很多時間)
C++ 則是用Createfile涵式Readfile涵式WriteFile涵式
一般打Google打Createfile就會有很多相關資訊
如果要用免費的軟體C++可以考慮Dev-C ++
如果想用有圖形介面又免費的可以考慮
Microsoft Visual Studio 2008 Express 版 SP1
http://www.microsoft.com/zh-tw/download/details.aspx?id=20682
裡面有VB.NET跟C#可以用的說
VB.NET開啟Com Port的方法(VB.NET寫法幾乎跟C#都是大同小異)
VB.NET 開打Com的範例
Imports System.IO.Ports
Imports System.Threading
Imports System.Text
Public Class Form1 Public myPort As New System.IO.Ports.SerialPort
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click '設定參數
With myPort
.BaudRate = 9600
.DataBits = 8
.Parity = Parity.None
.StopBits = StopBits.One
.PortName = "COM3"
'.ReadTimeout = 1000
.Encoding = System.Text.Encoding.ASCII
.ReadTimeout = 1000
End With
Dim read_word As String
read_word = ""
Try myPort.Open() '開啟
Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Dim InStr As String
InStr = ""
Try
myPort.ReadTimeout = 1000
InStr = myPort.ReadExisting()
If InStr.Length = 0 Then
Exit Sub
Else
TextBox2.Text += InStr
TextBox2.Text += "ok"
End If
Catch ex As Exception
MessageBox.Show("讀取錯誤:" + ex.ToString, "錯誤通知", MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
End Try
然後參考馬達跟超音波的範例: http://cellbots.googlecode.com/svn-history/r15/trunk/android/Mindstorms_NXT/src/com/googlecode/cellbots/nxt/NxtConnectionService.java 你會看到 public int setMotor(String srcApp, int motor, int power) { =>馬達 public int setUltraSonicSensor(String srcApp, int port) { =>超音波
