/// \par Overview
/// This byte-buffer structure provides an easy and efficient way to store
/// and process a stream of bytes.  You can create as many buffers as you
/// like (within memory limits), and then use this common set of functions to
/// access each buffer.  The buffers are designed for FIFO operation (first
/// in, first out).  This means that the first byte you put in the buffer
/// will be the first one you get when you read out the buffer.  Supported
/// functions include buffer initialize, get byte from front of buffer, add
/// byte to end of buffer, check if buffer is full, and flush buffer.  The
/// buffer uses a circular design so no copying of data is ever necessary.
/// This buffer is not dynamically allocated, it has a user-defined fixed
/// maximum size.  This buffer is used in many places in the avrlib code.

//
// How to use printf
// -----------------
//
// 1) Define FILE structure
//
// static FILE lcd_stream = FDEV_SETUP_STREAM(lcd_putc_stream, NULL, _FDEV_SETUP_WRITE);
//
// 2) Connect it with standard output
//
// stdout = &lcd_stream; // Connect stdout to LCD Stream
//
// 3) Use printf
//
// printf("\fHello World!\n------------");
//
// 4) Use special chars
//
// \f - clear display and goto home
// \n - goto the beginning of the next line
// \r - goto to the beginning of curent line
// \b - backspace
// \v - start and end definition of user defined char
//
//
// How to use User Defined symbols
// -------------------------------
//
// That is easy. Just print the definition to lcd. Look at the example
//
// printf("\v" "\x10" LCD_CHAR_BAT50 "\v"); // definition (redefines CGRAM content of the LCD)
// printf("Battery Status \x10"); // usage
//
// \v starts the definition
// \x10 first (of eight) user defined char
// LCD_CHAR_BAT50 half battery symbol, you can define more symbols here (up to 8)

// Target MCU : Atmel AVR series

// Description : This include file contains additional port and pin defines
// to help make code transparently compatible with the mega128. As in
// the other AVR processors, using defines like PD2 to denote PORTD, pin2
// is not absolutely necessary but enhances readability. The mega128 io.h
// no longer defines individual pins of ports (like PD2 or PA5, for
// example). Instead, port pins are defines universally for all ports as
// PORT0 through PORT7. However, this renaming causes a code-portability
// issue from non-mega128 AVRs to the mega128. Including this file will
// replace the missing defines.

/// The rprintf function library provides a simplified (reduced) version of
/// the common C printf() function.  See the code files for details about
/// which printf features are supported.  Also in this library are a
/// variety of functions for fast printing of certain common data types
/// (variable types).  Functions include print string from RAM, print
/// string from ROM, print string snippet, print hex byte/short/long, and
/// a custom-formatted number print, as well as an optional floating-point
/// print routine.
///
/// \note All output from the rprintf library can be directed to any device
/// or software which accepts characters.  This means that rprintf output
/// can be sent to the UART (serial port) or can be used with the LCD
/// display libraries to print formatted text on the screen.

/// \defgroup timer Timer Function Library (timer.c)
/// \code #include "timer.h" \endcode
/// \par Overview
/// This library provides functions for use with the timers internal
/// to the AVR processors. Functions include initialization, set prescaler,
/// calibrated pause function (in milliseconds), attaching and detaching of
/// user functions to interrupts, overflow counters, PWM. Arbitrary
/// frequency generation has been moved to the Pulse Library.
///
/// \par About Timers
/// The Atmel AVR-series processors each contain at least one
/// hardware timer/counter. Many of the processors contain 2 or 3
/// timers. Generally speaking, a timer is a hardware counter inside
/// the processor which counts at a rate related to the main CPU clock
/// frequency. Because the counter value increasing (counting up) at
/// a precise rate, we can use it as a timer to create or measure
/// precise delays, schedule events, or generate signals of a certain
/// frequency or pulse-width.
/// \par
/// As an example, the ATmega163 processor has 3 timer/counters.
/// Timer0, Timer1, and Timer2 are 8, 16, and 8 bits wide respectively.
/// This means that they overflow, or roll over back to zero, at a
/// count value of 256 for 8bits or 65536 for 16bits. A prescaler is
/// avaiable for each timer, and the prescaler allows you to pre-divide
/// the main CPU clock rate down to a slower speed before feeding it to
/// the counting input of a timer. For example, if the CPU clock
/// frequency is 3.69MHz, and Timer0's prescaler is set to divide-by-8,
/// then Timer0 will "tic" at 3690000/8 = 461250Hz. Because Timer0 is
/// an 8bit timer, it will count to 256 in just 256/461250Hz = 0.555ms.
/// In fact, when it hits 255, it will overflow and start again at
/// zero. In this case, Timer0 will overflow 461250/256 = 1801.76
/// times per second.
/// \par
/// Timer0 can be used a number of ways simultaneously. First, the
/// value of the timer can be read by accessing the CPU register \c TCNT0.
/// We could, for example, figure out how long it takes to execute a
/// C command by recording the value of \c TCNT0 before and after
/// execution, then subtract (after-before) = time elapsed. Or we can
/// enable the overflow interrupt which goes off every time T0
/// overflows and count out longer delays (multiple overflows), or
/// execute a special periodic function at every overflow.
/// \par
/// The other timers (Timer1 and Timer2) offer all the abilities of
/// Timer0 and many more features. Both T1 and T2 can operate as
/// general-purpose timers, but T1 has special hardware allowing it to
/// generate PWM signals, while T2 is specially designed to help count
/// out real time (like hours, minutes, seconds). See the
/// Timer/Counter section of the processor datasheet for more info.

/// \defgroup uart UART Driver/Function Library (uart.c)
/// \code #include "uart.h" \endcode
/// \par Overview
/// This library provides both buffered and unbuffered transmit and receive
/// functions for the AVR processor UART.  Buffered access means that the
/// UART can transmit and receive data in the "background", while your code
/// continues executing.  Also included are functions to initialize the
/// UART, set the baud rate, flush the buffers, and check buffer status.
///
/// \note For full text output functionality, you may wish to use the rprintf
/// functions along with this driver.
///
/// \par About UART operations
/// Most Atmel AVR-series processors contain one or more hardware UARTs
/// (aka, serial ports). UART serial ports can communicate with other
/// serial ports of the same type, like those used on PCs. In general,
/// UARTs are used to communicate with devices that are RS-232 compatible
/// (RS-232 is a certain kind of serial port).
/// \par
/// By far, the most common use for serial communications on AVR processors
/// is for sending information and data to a PC running a terminal program.
/// Here is an exmaple:
/// \code
/// uartInit(); // initialize UART (serial port)
/// uartSetBaudRate(9600); // set UART speed to 9600 baud
/// rprintfInit(uartSendByte); // configure rprintf to use UART for output
/// rprintf("Hello World\r\n"); // send "hello world" message via serial port
/// \endcode
///
/// \warning The CPU frequency (F_CPU) must be set correctly in \c global.h
/// for the UART library to calculate correct baud rates. Furthermore,
/// certain CPU frequencies will not produce exact baud rates due to
/// integer frequency division round-off. See your AVR processor's
/// datasheet for full details.

/// \defgroup uart2 UART Driver/Function Library for dual-UART processors (uart2.c)
/// \code #include "uart2.h" \endcode
/// \par Overview
/// This is a UART driver for AVR-series processors with two hardware
/// UARTs such as the mega161 and mega128. This library provides both
/// buffered and unbuffered transmit and receive functions for the AVR
/// processor UART. Buffered access means that the UART can transmit
/// and receive data in the "background", while your code continues
/// executing.  Also included are functions to initialize the UARTs,
/// set the baud rate, flush the buffers, and check buffer status.
///
/// \note For full text output functionality, you may wish to use the rprintf
/// functions along with this driver.
///
/// \par About UART operations
/// Most Atmel AVR-series processors contain one or more hardware UARTs
/// (aka, serial ports). UART serial ports can communicate with other
/// serial ports of the same type, like those used on PCs. In general,
/// UARTs are used to communicate with devices that are RS-232 compatible
/// (RS-232 is a certain kind of serial port).
/// \par
/// By far, the most common use for serial communications on AVR processors
/// is for sending information and data to a PC running a terminal program.
/// Here is an exmaple:
/// \code
/// uartInit(); // initialize UARTs (serial ports)
/// uartSetBaudRate(0, 9600); // set UART0 speed to 9600 baud
/// uartSetBaudRate(1, 115200); // set UART1 speed to 115200 baud
///
/// rprintfInit(uart0SendByte); // configure rprintf to use UART0 for output
/// rprintf("Hello UART0\r\n"); // send "hello world" message via UART0
///
/// rprintfInit(uart1SendByte); // configure rprintf to use UART1 for output
/// rprintf("Hello UART1\r\n"); // send "hello world" message via UART1
/// \endcode
///
/// \warning The CPU frequency (F_CPU) must be set correctly in \c global.h
/// for the UART library to calculate correct baud rates. Furthermore,
/// certain CPU frequencies will not produce exact baud rates due to
/// integer frequency division round-off. See your AVR processor's
/// datasheet for full details.
