Utilizando el MonoDevelop en Linux, creé en gtk# un proyecto, coloqué sólo un botón en el formulario. Sólo quiero abrir el puerto serie y enviar un byte al puerto serie.
El código completo hasta ahora es:
Código:
// MainWindow.cs created with MonoDevelop

//
using System;
using Gtk;
using System.IO.Ports;
public partial class MainWindow: Gtk.Window
{
public MainWindow (): base (Gtk.WindowType.Toplevel)
{
Build ();
}
protected void OnDeleteEvent (object sender, DeleteEventArgs a)
{
Application.Quit ();
a.RetVal = true;
}
public SerialPort mySerial;
protected virtual void OnButtonTClicked (object sender, System.EventArgs e)
{
mySerial = new SerialPort("/dev/ttyS0", 9600, Parity.None, 8, StopBits.Two);
mySerial.Open();
byte[] mBuffer = new byte[1];
mBuffer[0] = 0x74; // LA letra t.
mySerial.Write(mBuffer, 0, mBuffer.Length);
mySerial.Close();
}
}
Al ejecutar se ejecuta sin problemas, pero lo hay al pulsar el botón y me muestra este menaje de errores o algo parecido y no envía nada al puerto serie y quiero resolver este problema.
