Need to implement a timer in a console application RRS feed

  • Question

  • Hi everyone,

    I have the following code and it perfectly works to read from the serial port and receive data.

    However, I would like to read the port continuously and in a real time basis.

    So, I decide to use the timer, but I don't know how to proceed

    Thank you.

    using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO.Ports; //namespace containing SerialPort Class using System.Threading.Tasks; using System.Threading; using System.Timers; namespace Project { class Program { public static string RxedData; // String to store received data public static string Rtr = "\n"; public static string s1 = "AT"; public static SerialPort MyCOMPort = new SerialPort(); public static System.Timers.Timer timer = new System.Timers.Timer(); public static FAN t = new FAN(); public static Compressor C = new Compressor(); public static void Main(string[] args) { { //----------------------------------------------------------------------------------------- // COM port settings //----------------------------------------------------------------------------------------- MyCOMPort.PortName = "COM3"; // Name of the COM port MyCOMPort.BaudRate = 38400; // Baudrate = 38400bps MyCOMPort.Parity = Parity.None; // Parity bits = none MyCOMPort.DataBits = 8; // No of Data bits = 8 MyCOMPort.StopBits = StopBits.One; // No of Stop b MyCOMPort.NewLine = "\r\n"; // MyCOMPort.Handshake = Handshake.None; MyCOMPort.DtrEnable = true; MyCOMPort.RtsEnable = true; MyCOMPort.DataReceived += new SerialDataReceivedEventHandler(DataReceivedHandler); MyCOMPort.Open(); // Open the port //------------------------------------------------------------------------------------------ FAN.speed = 2000; // Functions' call // t.Set_FAN_SPEED(); // t.Stop_FAN(); C.CompressorRun(); //C.CompressorStop(); Console.Write("\n"); Console.ReadKey(); do { t.Get_FAN_Speed(); C.GetCompressorState(); Console.Write("\n"); Console.ReadKey(); } while (true); // C.CompressorStop(); MyCOMPort.Close(); // Close port } } private static void DataReceivedHandler(object sender, SerialDataReceivedEventArgs e) { SerialPort sp = (SerialPort)sender; Program.RxedData = sp.ReadExisting(); Console.Write(Program.RxedData); } } }

  • Hi i.Hjr,

    Please try the code below.

     static void Main(string[] args)
                Timer aTimer = new Timer();
                aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);
                aTimer.Interval = 1000;//set the time interval
                aTimer.Enabled = true;
                Console.WriteLine("Press \'q\' to quit the sample.");
                while (Console.Read() != 'q') ;
            // Specify what you want to happen when the Elapsed event is raised.
            private static void OnTimedEvent(object source, ElapsedEventArgs e)
                //Please put the method which you run to read the port continuously and in a real time basis.
