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
|
||||
|
||||
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 UART0[1]_RX_BUFFER_SIZE and UART0[1]_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 UART0[1]_RX_BUFFER_SIZE and UART0[1]_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 += -DUART0[1]_RX_BUFFER_SIZE=nn -DUART0[1]_RX_BUFFER_SIZE=nn to your Makefile.
