#3007 — Let Ruby read the serial port

Hello everyone,

I would like to read a serial port. I'm going to connect want to connect
my Arduino Uno microcontroller board to the computer via USB. It acts as
a virtual serial port automatically. I can already read with the Arduino
IDE' s serialterminal.

Processing can also read a serialport from a Arduino.

But now I would like to let Ruby read the virtual serialport and save
the data in a variable. And then do a lots of stuff with it.

Is there a special library or gem for this? I already installed libusb
for ruby.

Greetings,

Superpelican

Which platform are you running under?

The ruby-serialport gem worked fine for me (under Linux) when I last 
tried it, although that was several years ago.

Make sure you have the baud and port number correct.
It's an often overlooked part of connecting to serial.
https://github.com/tenderlove/ruby-serialport
This might help also.
It also supports windows as well as linux (and theoretically mac)

[Note:  parts of this message were removed to make it a legal post.]

Almost a year ago I used http://rubygems.org/gems/serialport successfully on
my Mac to talk to USB and Bluetooth Arduinos.

I use IronRuby  :

require "mscorlib"
require "System.Windows.Forms"



 def portConfigure(portName,bauds,bits,stop,parity)
    @components = System::ComponentModel::Container.new()
    @serialPort1 = System::IO::Ports::SerialPort.new(@components)
    portName ||= "COM3"
    bauds ||= "9600"
    bits ||= "8"
    stopBits ||= "1"
    parity ||= "none"
    #puts "Configure..."
    @serialPort1.DtrEnable = true
    @serialPort1.RtsEnable = true
    @serialPort1.PortName = portName
    @serialPort1.StopBits = stopBits.to_i
    @serialPort1.BaudRate = bauds.to_i
    @serialPort1.DataBits = bits.to_i
    @serialPort1.Open()
    @serialPort1.DataReceived do |sender, e|
       buff = @serialPort1.ReadExisting()
       scanner(buff)
    end
  end
  def writeString(str)
    buf = System::Text::Encoding.GetEncoding("ASCII").GetBytes(str)
    size = buf.Length
    @serialPort1.Write(buf, 0, size)
  end
