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.

* @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.
