JRuby Serial Port Gem

JRuby wrapper for serial port communication mimicking the functionality of the ruby-serialport gem

Based off of pragpub and jr_serial_port projects.

Requirements

Must have the librxtxSerial libraries in your java paths.

An example of the files can be found at the this RXTX wiki

If you're having trouble on OSX, check out this site: jlog.org

Usage

Include jruby-serial port in your Gemfile:

#gem is not published yet
gem "jruby-serialport", :git => "git://github.com/pmukerji/jruby-serialport.git"

If you have an application you want to run with JRuby and Ruby then you can specify the platform. For example:

platforms :jruby do
  gem "jruby-serialport", :git => "git://github.com/pmukerji/jruby-serialport.git"
end

platforms :ruby do
  gem "serialport", :git => "git://github.com/pmukerji/ruby-serialport.git"
end

Use jruby-serialport in your application:

require "serialport"

serial_port = SerialPort.new "/dev/ttyUSB0", 38400 # optional data_bits=8, stop_bits=1, parity=GnuSerialPort::PARITY_NONE

serial_port.read_timeout = 1000 # Read Timeout in milliseconds

serial_port.write "output data" # returns length (in bytes) of the message written

num_bytes_to_read = 5

serial_port.read num_bytes_to_read # returns message or whatever could be read before timeout was reached

Tests

There are currently only a few tests written for this library. Please add some!
