ccutrer-serialport
SerialPort is a simple Ruby gem for interacting with serial ports.
It does not require an extension thanks to using FFI.
SerialPort objects inherit from File (and thus IO), so are compatible with all
IO methods, in particular read_partial, and asynchronous IO.
It was inspired by the rubyserial gem.
Usage
require 'ccutrer-rubyserial'
serialport = CCutrer::SerialPort.new '/dev/ttyACM0' # Defaults to 9600 baud, 8 data bits, and no parity
serialport = CCutrer::SerialPort.new '/dev/ttyACM0', baud: 57600
serialport = CCutrer::SerialPort.new '/dev/ttyACM0', baud: 19200, data_bits: 8, parity: :even
serialport.read(4096)
serialport.gets
require 'io/wait'
serialport.ready?
