// Author		: Pascal Stang - Copyright (C) 2002-2003
// Created		: 7/20/2002

// Version		: 0.6
// Target MCU	: Atmel AVR Series (intended for the ATmega16 and ATmega32)
// Editor Tabs	: 4
//
// Description	:
//		This uart library emulates the operation of a UART (serial port) using
//	the AVR's hardware timers, I/O pins, and some software.
//
//	Specifically, this code uses:
//		-Timer 2 Output Capture for transmit timing
//		-Timer 0 Output Capture for receive timing
//		-External Interrupt 2 for receive triggering
//
//	The above resources cannot be used for other purposes while this software
//	UART is enabled.  The overflow interrupts from Timer0 and Timer2 can still
//	be used for other timing, but the prescalers for these timers must not be
//	changed.
//
//	Serial output from this UART can be routed to any I/O pin.  Serial input
//	for this UART must come from the External Interrupt 2 (INT2) I/O pin.
//	These options should be configured by editing your local copy of
//	"uartsw2conf.h".
