/*
ByteBuffer.h - A circular buffer implementation for Arduino
Created by Sigurdur Orn, July 19, 2010. siggi@mit.edu
Updated by GreyGnome (aka Mike Schwager) Thu Feb 23 17:25:14 CST 2012
added the putString() method and the fillError variable.
added the checkError() and resetError() methods. The checkError() method resets the fillError variable
to false as a side effect.
added the ByteBuffer(unsigned int buf_size) constructor.
added the init() method, and had the constructor call it automagically.
protected certain sections of the code with cli()/sei() calls, for safe use by interrupts.
Also made the capacity, position, length, and fillError variables volatile, for safe use by interrupts.
