使用 arduino模拟OBD车载诊断系统 对于车载诊断系统的学习有很大帮助(Using Arduino to simulate OBD on-board diagnostic system is very helpful for the study of on-board diagnostic system)

vxworks下bdb程序，包含连接数据库、插入、查找、删除等操作(bdb procedures under vxworks, including connecting to the database, insert, search, and delete)

利用VB寫的DirectShow看影片的源碼,利用Filter建置完成(Using VB to write to see the DirectShow video source, use Filter to build complete)

private void Connect_Click(object sender, System.EventArgs e)        {            //将光标置为等待状态            Cursor cr = Cursor.Current;            Cursor.Current = Cursors.WaitCursor;            String a ,b,c;              //用110端口新建POP3服务器连接            Server = new TcpClient(PopServer.Text, 110);            Status.Items.Clear();             try            {                //初始化                NetStrm = Server.GetStream();                RdStrm = new StreamReader(Server.GetStream());                Status.Items.Add(RdStrm.ReadLine());                 //登录服务器过程                Data = "USER " Username.Text CRLF;                szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());                NetStrm.Write(szData, 0, szData.Length);                Status.Items.Add(RdStrm.ReadLine());                 Data = "PASS " Password.Text CRLF;                szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());                NetStrm.Write(szData, 0, szData.Length);                Status.Items.Add(RdStrm.ReadLine());                 //向服务器发送STAT命令，从而取得邮箱的相关信息：邮件数量和大小                Data = "STAT" CRLF;                szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());                NetStrm.Write(szData, 0, szData.Length);                //Status.Items.Add(RdStrm.ReadLine());                 //改变按钮的状态                Connect.Enabled = false;                Disconnect.Enabled = true;                Retrieve.Enabled = true;                 //将光标置回原来状态                Cursor.Current = cr;             }            catch (InvalidOperationException err)            {                Status.Items.Add("Error: " err.ToString());            }        }

1 两路编码器输入通道 2 采用专用编码器计数芯片完成计数工作 3 与上位机串口通讯(1 two-way encoder input channel 2 using a dedicated encoder chip count as counting work 3 serial communication with the host computer)
