/*************************************************************************
Title: Interrupt UART library with receive/transmit circular buffers
Author: Peter Fleury <pfleury@gmx.ch> http://jump.to/fleury
File: $Id: uart.c,v 1.10 2013/06/02 07:27:04 peter Exp $
Software: AVR-GCC 4.1, AVR Libc 1.4.6 or higher
Hardware: any AVR with built-in UART,
License: GNU General Public License
DESCRIPTION:
An interrupt is generated when the UART has finished transmitting or
receiving a byte. The interrupt handling routines use circular buffers
for buffering received and transmitted data.
The UART_RX_BUFFER_SIZE and UART_TX_BUFFER_SIZE variables define
the buffer size in bytes. Note that these variables must be a
power of 2.
USAGE:
Refere to the header file uart.h for a description of the routines.
See also example test_uart.c.

Based on Atmel Application Note AVR306

*
* @brief Interrupt UART library using the built-in UART with transmit and receive circular buffers.
*
* This library can be used to transmit and receive data through the built in UART.
*
* An interrupt is generated when the UART has finished transmitting or
* receiving a byte. The interrupt handling routines use circular buffers
* for buffering received and transmitted data.
*
* The UART_RX_BUFFER_SIZE and UART_TX_BUFFER_SIZE constants define
* the size of the circular buffers in bytes. Note that these constants must be a power of 2.
* You may need to adapt this constants to your target and your application by adding
* CDEFS += -DUART_RX_BUFFER_SIZE=nn -DUART_RX_BUFFER_SIZE=nn to your Makefile.
*

/*************************************************************************
Title: Interrupt UART library with receive/transmit circular buffers
Author: Peter Fleury <pfleury@gmx.ch> http://jump.to/fleury
File: $Id: uart.c,v 1.10 2013/06/02 07:27:04 peter Exp $
Software: AVR-GCC 4.1, AVR Libc 1.4.6 or higher
Hardware: any AVR with built-in UART,
License: GNU General Public License
DESCRIPTION:
An interrupt is generated when the UART has finished transmitting or
receiving a byte. The interrupt handling routines use circular buffers
for buffering received and transmitted data.
The UART_RX_BUFFER_SIZE and UART_TX_BUFFER_SIZE variables define
the buffer size in bytes. Note that these variables must be a
power of 2.
USAGE:
Refere to the header file uart.h for a description of the routines.
See also example test_uart.c.

Based on Atmel Application Note AVR306

/*************************************************************************
Title: Interrupt UART library with receive/transmit circular buffers
Author: Peter Fleury <pfleury@gmx.ch> http://jump.to/fleury
File: $Id: uart.c,v 1.10 2013/06/02 07:27:04 peter Exp $
Software: AVR-GCC 4.1, AVR Libc 1.4.6 or higher
Hardware: any AVR with built-in UART,
License: GNU General Public License
DESCRIPTION:
An interrupt is generated when the UART has finished transmitting or
receiving a byte. The interrupt handling routines use circular buffers
for buffering received and transmitted data.
The UART_RX_BUFFER_SIZE and UART_TX_BUFFER_SIZE variables define
the buffer size in bytes. Note that these variables must be a
power of 2.
USAGE:
Refere to the header file uart.h for a description of the routines.
See also example test_uart.c.
NOTES:
Based on Atmel Application Note AVR306

*
* @brief Interrupt UART library using the built-in UART with transmit and receive circular buffers.
*
* This library can be used to transmit and receive data through the built in UART.
*
* An interrupt is generated when the UART has finished transmitting or
* receiving a byte. The interrupt handling routines use circular buffers
* for buffering received and transmitted data.
*
* The UART_RX_BUFFER_SIZE and UART_TX_BUFFER_SIZE constants define
* the size of the circular buffers in bytes. Note that these constants must be a power of 2.
* You may need to adapt this constants to your target and your application by adding
* CDEFS += -DUART_RX_BUFFER_SIZE=nn -DUART_RX_BUFFER_SIZE=nn to your Makefile.
*

/*************************************************************************
Title: Interrupt UART library with receive/transmit circular buffers
Author: Peter Fleury <pfleury@gmx.ch> http://jump.to/fleury
File: $Id: uart.c,v 1.10 2013/06/02 07:27:04 peter Exp $
Software: AVR-GCC 4.1, AVR Libc 1.4.6 or higher
Hardware: any AVR with built-in UART,
License: GNU General Public License
DESCRIPTION:
An interrupt is generated when the UART has finished transmitting or
receiving a byte. The interrupt handling routines use circular buffers
for buffering received and transmitted data.
The UART_RX_BUFFER_SIZE and UART_TX_BUFFER_SIZE variables define
the buffer size in bytes. Note that these variables must be a
power of 2.
USAGE:
Refere to the header file uart.h for a description of the routines.
See also example test_uart.c.
NOTES:
Based on Atmel Application Note AVR306

*
* @brief Interrupt UART library using the built-in UART with transmit and receive circular buffers.
*
* This library can be used to transmit and receive data through the built in UART.
*
* An interrupt is generated when the UART has finished transmitting or
* receiving a byte. The interrupt handling routines use circular buffers
* for buffering received and transmitted data.
*
* The UART_RX_BUFFER_SIZE and UART_TX_BUFFER_SIZE constants define
* the size of the circular buffers in bytes. Note that these constants must be a power of 2.
* You may need to adapt this constants to your target and your application by adding
* CDEFS += -DUART_RX_BUFFER_SIZE=nn -DUART_RX_BUFFER_SIZE=nn to your Makefile.
*
* @note Based on Atmel Application Note AVR306

/*************************************************************************
Title: Interrupt UART library with receive/transmit circular buffers
Author: Peter Fleury <pfleury@gmx.ch> http://jump.to/fleury
File: $Id: uart.c,v 1.10 2013/06/02 07:27:04 peter Exp $
Software: AVR-GCC 4.1, AVR Libc 1.4.6 or higher
Hardware: any AVR with built-in UART,
License: GNU General Public License
DESCRIPTION:
An interrupt is generated when the UART has finished transmitting or
receiving a byte. The interrupt handling routines use circular buffers
for buffering received and transmitted data.
The UART_RX_BUFFER_SIZE and UART_TX_BUFFER_SIZE variables define
the buffer size in bytes. Note that these variables must be a
power of 2.
USAGE:
Refere to the header file uart.h for a description of the routines.
See also example test_uart.c.
NOTES:
Based on Atmel Application Note AVR306

*
* @brief Interrupt UART library using the built-in UART with transmit and receive circular buffers.
*
* This library can be used to transmit and receive data through the built in UART.
*
* An interrupt is generated when the UART has finished transmitting or
* receiving a byte. The interrupt handling routines use circular buffers
* for buffering received and transmitted data.
*
* The UART_RX_BUFFER_SIZE and UART_TX_BUFFER_SIZE constants define
* the size of the circular buffers in bytes. Note that these constants must be a power of 2.
* You may need to adapt this constants to your target and your application by adding
* CDEFS += -DUART_RX_BUFFER_SIZE=nn -DUART_RX_BUFFER_SIZE=nn to your Makefile.
*
* @note Based on Atmel Application Note AVR306
