  1. POHow do I use dataReceived event of the SerialPort Port Object in C#?
    text
    copied!<p>I am attempting to create a small application to collect data received from an external sensor attached to COM10. I have successfully created a small C# console object and application that opens the port and streams data to a file for a fixed period of time using a for-loop. </p> <p>I would like to convert this application to use the dataReceived event to stream instead. After reading the <a href="http://blogs.msdn.com/bclteam/archive/2006/10/10/Top-5-SerialPort-Tips-_5b00_Kim-Hamilton_5D00_.aspx" rel="nofollow noreferrer">Top 5 SerialPort Tips</a>, I still can't seem to it to work and don't know what I am missing. I rewrote the console application so that all the code is in Main and is pasted below. Can someone please help enlighten me as to why the event handler port_OnReceiveDatazz is not being called even though I know that there is data being sent to the port by the hardware?</p> <p>Thanks</p> <p>Azim</p> <p>PS: Thanks to <a href="https://stackoverflow.com/questions/466474/how-do-i-use-datareceived-event-of-the-serialport-port-object-in-c#466577">@Gabe</a>, <a href="https://stackoverflow.com/questions/466474/how-do-i-use-datareceived-event-of-the-serialport-port-object-in-c#466510">@Jason Down</a>, and <a href="https://stackoverflow.com/questions/466474/how-do-i-use-datareceived-event-of-the-serialport-port-object-in-c#466518">@abatishchev</a> for all the suggestions. I am stumped and can't seem to get the event handler to work. Perhaps it has something to do with the device. I can live with just reading the port in a thread and streaming the data straight to file.</p> <hr> <p><strong>Code</strong></p> <hr> <pre><code>namespace serialPortCollection { class Program { static void Main(string[] args) { const int bufSize = 2048; Byte[] buf = new Byte[bufSize]; //To store the received data. SerialPort sp = new SerialPort("COM10", 115200); sp.DataReceived += port_OnReceiveDatazz; // Add DataReceived Event Handler sp.Open(); sp.WriteLine("$"); //Command to start Data Stream // Wait for data or user input to continue. Console.ReadLine(); sp.WriteLine("!"); //Stop Data Stream Command sp.Close(); } // My Event Handler Method private static void port_OnReceiveDatazz(object sender, SerialDataReceivedEventArgs e) { SerialPort spL = (SerialPort) sender; const int bufSize = 12; Byte[] buf = new Byte[bufSize]; Console.WriteLine("DATA RECEIVED!"); Console.WriteLine(spL.Read(buf, 0, bufSize)); } } } </code></pre>
