BufferedSerial (BufferedSerial.h)

Arduino Buffered Serial https://code.google.com/p/arduino-buffered-serial/ -- This project includes Arduino libraries to perform buffered, interrupt driven, serial communication with a host application (Processing example included). This provides significant benefit over the good-old Serial.println("some ascii") method both as it has more efficient storage of numerical data as integers, longs, bytes or floats rather than ascii coded strings, as well as being interrupt driven so that it doesn't block the operation of the device.
