Hi there ! I'm working on a project where i need to read a stream from arduino. I tried use C# but i'm having problems with the Read() function freezing the game, the ReadExisting doesn't recieve anything and the event SerialDataReceivedEventHandler is never triggered. I tried to do the same thing in js but i can't get it work, it's say that "stream.on" its not a member of System.IO.Ports. Here is the code in C# and the code in js.
**C# Code**:
using UnityEngine;
using System.Collections;
using System.IO.Ports;
using System;
public class LectorEncoder : MonoBehaviour
{
public string puerto = "/dev/ttyACM1";
SerialPort stream; //Establezco un stream con el puerto (com4) y el baud (11500)
//float[] lastRot = {0,0,0}; //Need the last rotation to tell how far to spin the camera
public bool abroPuerto = false;
public bool cierro = false;
void Start ()
{
stream = new SerialPort (puerto, 115200);
}
// Update is called once per frame
void Update ()
{
if (abroPuerto && !stream.IsOpen)
{
try
{
stream.DataReceived += new SerialDataReceivedEventHandler(DataReceivedHandler);
stream.Open (); //Abro el stream del puerto serial.
stream.ReadTimeout = 1000;
Debug.Log("Esta abierto: "+stream.IsOpen);
}
catch (Exception e)
{
Debug.Log("ups: "+e.ToString());
}
}
if (cierro) {
stream.Close ();
abroPuerto = false;
}
//this.algo ();
}
public void algo()
{
if (stream.IsOpen) {
try
{
//Debug.Log ("Antes de leer");
string value = stream.ReadExisting (); //Leo la informacion del Stream
Debug.Log ("Lectura: " + value);
}
catch (Exception e)
{
Debug.Log("ups: "+e.ToString());
}
} else {
Debug.Log ("El puerto no está abierto");
}
}
**JS Code:**
#pragma strict
import System.IO.Ports;
public static var stream : SerialPort;
public var nombrePuerto = "/dev/ttyACM1";
public var abroPuerto = false;
public var cierro = false;
function Start ()
{
CrearSerialPort();
}
function Update ()
{
AbrirConexion();
}
function CrearSerialPort()
{
stream = new SerialPort ();
stream.BaudRate = 115200;
stream.PortName = nombrePuerto;
stream.Parity = Parity.None;
stream.DataBits = 8;
stream.StopBits = StopBits.One;
}
function AbrirConexion()
{
if (abroPuerto && !stream.IsOpen)
{
Debug.Log("Antes del Try");
try
{
stream.Open (); //Abro el stream del puerto serial.
stream.ReadTimeout = 1000;
Debug.Log("Esta abierto: "+stream.IsOpen);
}
catch (ex)
{
Debug.Log("Error: "+ex.ToString());
}
}
if (cierro)
{
Debug.Log("Entro a Cierro");
stream.Close ();
abroPuerto = false;
}
}
function LeerDatos()
{
try
{
var receivedData = "";
Debug.Log("Entro a LeerDatos()");
}
catch (ex)
{
Debug.Log("Error: "+ex.ToString());
}
stream.on('data', function(data)
{
Debug.Log("Entro a Stream.On()");
receivedData += data.ToString();
Debug.Log("Termino de leer: "+receivedData);
});
}
function OnApplicationQuit()
{
stream.Close();
}
