AVRA is an assembler for Atmel AVR microcontrollers, and it is almost
compatible with Atmel’s own assembler AVRASM32. The differences
between the two are:
Support for some extra preprocessor directives.
includes: .define, .undef, .ifdef, .ifndef, .if, .else, .endif,
Not all command line options are supported.
Specifying an eeprom file (-e) is not supported. All eeprom data
is put out into a file called program.eep.hex and always Intel
hex format. Other hex file formats than Intel are currently not
Forward references are not supported.
Like in C, you have to define everything before you are using
it, excepting labels. This makes sure, that directives like
.ifdef and .undef are working properly. If you are familiar with
the C programming language, you should get easily into AVRA. See
chapter "Programming techniques" for more information about how
to write proper code.
Enhanced macro support.
AVRA has some new features for writing flexible macros. This
should increase the ability to reuse code e.g. build your own
AVRA creates a coff file everytime the assembly was sucessful.
This file allows AVR Studio or any coff compatible debugger to
simulate or emulate the program.
Meta tags for assembly time.
This helps you tracking versions of your software and can also
be used to generate customer specific serial numbers.
Several option can be given after one ’-’, but if an option requires an
argument; the argument must be given after that option.
Create list file
Create map file
Additional include dirs.
List macro expansion in listfile.
Maximum number of errors before exit (default: 10)
List out supported devices.
Show summary of options.
The initial version of AVRA was written by John Anders Haugum. He
released all versions until v0.7. All later versions were released by
