-/*************************************************************************
-Title:    Interrupt UART library with receive/transmit circular buffers
-Author:   Peter Fleury <pfleury@gmx.ch>   http://jump.to/fleury
-File:     $Id: uart.c,v 1.12 2014/01/08 21:58:12 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
+/* USART-Init beim ATmegaXX */

-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.
-

 *
- *  @brief Interrupt UART library using the built-in UART with transmit and
- *         receive circular buffers.
+ * #define F_CPU 16000000         // Oszillator-Frequenz in Hz
+ * #define UART_INTERRUPT 1
+ * #define UART_BAUD_RATE 19200
+ * #define UART_RXBUFSIZE 16
+ * #define UART_TXBUFSIZE 16
+ * #define UART_LINE_BUFFER_SIZE 40
+ * #define UART_LEDS             // LED1 and LED2 toggle on tx and rx interrupt
 *
- *  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.
