Serial data recieved help
Aug 10 2011 2:52 AM
in my first program i am recieving serial data from com 4 using this program:
#region Namespace Inclusions
using System;
using System.IO.Ports;
using System.Windows.Forms;
using System.Threading;
#endregion
namespace SerialPortExample
{
class SerialPortProgram
{
// Create the serial port with basic settings
private SerialPort port = new SerialPort("COM4", 9600, Parity.None, 8, StopBits.One);
[STAThread]
static void Main(string[] args)
{
// Instatiate this class
new SerialPortProgram();
}
private SerialPortProgram()
{
//Console.WriteLine("Incoming Data:");
// Attach a method to be called when there
// is data waiting in the port's buffer
port.DataReceived += new
SerialDataReceivedEventHandler(port_DataReceived);
// Begin communications
port.Open();
// Enter an application loop to keep this thread alive
Application.Run();
}
private void port_DataReceived(object sender,
SerialDataReceivedEventArgs e)
{
// Show all the incoming data in the port's buffer
string data = port.ReadExisting();
//Console.WriteLine(data);
Thread.Sleep(200);
System.IO.File.WriteAllText("C://Users//intel//Documents//Visual Studio 2010//Projects//ConsoleApplication4//serialdata2.txt", data);
Thread.Sleep(200);
// System.Diagnostics.Process.Start("C:\\Users\\intel\\Documents\\Visual Studio 2010\\Projects\\ConsoleApplication5\\ConsoleApplication5\\bin\\Debug\\ConsoleApplication5.exe");
port.Close();
Application.Exit();
}
}
}
then in my second program i am sending this data to com1 using this program:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO.Ports;
using System.Threading;
namespace cConsoleAppMonitorServoCompletion
{
class Program
{
static SerialPort _serialPort;
static void Main(string[] args)
{
// try
// {
_serialPort = new SerialPort("COM1",115200,Parity.None,8,StopBits.One);
//_serialPort.PortName = "COM1";
//_serialPort.BaudRate =
_serialPort.Open();
string data = System.IO.File.ReadAllText("C://Users//intel//Documents//Visual Studio 2010//Projects//ConsoleApplication4//serialdata2.txt");
// Console.Write(data == "45");
//oreach (char c in "#3 P1546 \r") Console.Write("{0:X2} ", (int)c);
//hread.Sleep(200000);
// foreach (char c in data) Console.Write("{0:X2} ", (int)c);
// Thread.Sleep(200000);
data= data.Substring(0, data.Length - 0) + "\r";
//string data2 = "#3 P1500 \r";
//Console.WriteLine(data2 == data);
//data.ToString();
//Thread.Sleep(200);
// StringComparison(data,"#3 P1500 \r");
// string data=System.IO.File.ReadAllText
_serialPort.Write(data);
// Console.WriteLine("#0 P500 \r");
//string output;
// output = "";
//Example: "Q <cr>"
// This will return a "." if the previous move is complete, or a "+" if it is still in progress.
/* while (!(output == ".")) //loop until you get back a period
{
_serialPort.Write("Q \r");
output = _serialPort.ReadExisting();
Console.WriteLine(output);
Thread.Sleep(10);
}*/
Thread.Sleep(100);
_serialPort.Close();
// }
// catch (TimeoutException) { }
}
}
}
now when i am running program one by one myself they are working fine but i want to run them in continuous loop that is for(i=0;i<10,i++)
