This is a serial library for many different Atmel AVR MCUs. It is using two FIFO Buffers per USART module for interrupt driven UART communication. XON/XOFF Flow control for incoming data can be enabled for all UART modules, it will operate independently for each.

Device-specific configuration is in serial_device.h. You should be able to easily add new AVR MCUs. Just get the relevant register and bit names from the data-sheet.

A small test application is included. It will be built when calling either of these commands

make all
make test.hex

You can also flash it with

make program

just adjust your MCU, programmer type and port in the makefile.

For normal use, either include serial.c, serial.h and serial_device.h in your project, or build a statically-linked library by calling

make lib

and linking this to your project, as well as including serial.h.

The more-or-less current Doxygen Documentation can be found on the web or as PDF...

The current list of supported / tested MCUs is:

AtMega8
AtMega16
AtMega32
AtMega8515
AtMega8535
AtMega323
AtMega168
AtMega328
AtMega48
AtMega88
AtMega168p
AtMega328p
AtMega48p
AtMega88p
AtMega2561
AtMega1281
AtMega1284p
AtMega2560
AtMega1280
AtMega640
AtTiny2313
AtTiny2313a
AtTiny4313
AtXMega128a1

but support for many more AVR cpus could be added easily by changing serial_device.h without large changes to the library code itself.
