用LabVIEW設計一個串列埠攝像頭拍照程式
用LabVIEW設計一個串列埠攝像頭拍照程式我幫你搞定~原創,
//建立一個串列埠通訊
SerialPort CurrentPort = null;
CurrentPort = new SerialPort();
CurrentPort。ReadBufferSize = 128;
CurrentPort。PortName = comName; //埠號
CurrentPort。BaudRate = bandRate; //位元率
CurrentPort。Parity =parity;//奇偶校驗
CurrentPort。StopBits = stop;//停止位
CurrentPort。DataBits = databit;//資料位
CurrentPort。ReadTimeout = 1000; //讀超時,即在1000內未讀到資料就引起超時異常
//繫結資料接收事件,因為傳送是被動的,所以你無法主動去獲取別人傳送的程式碼,只能透過這個事件來處理
CurrentPort。DataReceived += Sp_DataReceived;
CurrentPort。Open();
定義一個變數 byte[] receiveStr;
//繫結的事件處理函式
private static void Sp_DataReceived(object sender, System。IO。Ports。SerialDataReceivedEventArgs e)
{
SerialPort sp = sender as SerialPort;
if (sp == null)
return;
byte[] readBuffer = new byte[sp。ReadBufferSize];
sp。Read(readBuffer, 0, readBuffer。Length);
//賦值
receiveStr=readBuffer;//當然你可以透過轉換將byte[]轉換為字串。
