# AVRA *Assember for the Atmel AVR microcontroller family* AVRA is an assembler for Atmel AVR microcontrollers, and it is almost compatible with Atmel's own assembler, AVRASM32. AVRA is written in C99. ## Differences between AVRA and AVRASM32 There are some differences between the original Atmel assembler AVRASM32 and AVRA. Basically, AVRA is designed to replace AVRASM32 without special changes in your current Atmel AVR Studio enviroment. Command line options have been adapted as far as possible. Jumping to fault-containing lines directly by double-clicking on the error message in the output window does work as with AVRASM32. ### The differences in detail #### Support for some extra preprocessor directives .define, .undef, .ifdef, .ifndef, .if, .else, .endif, .elif, .elseif, .warning #### 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 is always in Intel hex format. Other hex file formats are currently not supported. #### Forward references not supported for .ifdef and .ifndef directives This makes sure that directives like .ifdef and .undef are working as you probably expect. If you are familiar with the C programming language, you should get easily into AVRA. #### 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 library. #### Debugging support AVRA creates a coff file everytime assembly is 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. ## Compatibility It should be possible to compile AVRA on most system platforms. If you have problems compiling AVRA, please open an issue in the tracker. ## History The initial version of AVRA was written by John Anders Haugum. He released all versions until v0.7. Tobias Weber later took over, followed by Burkhard Arenfeld (v1.2) then Jerry Jacobs (v1.3). After a long 8 years of inactivity, Virgil Dupras took over, preparing a v1.4 release. See AUTHORS for a complete list of contributors. ## Build To build the `avra` executable, cd into the project's root directory and run `make`. A `src/avra` binary will be produced. You can install it with `make install`. By default, make runs under the `linux` OS, which assumes a typical GNU toolchain. If that doesn't work for you, look at the available platforms available in `src/makefiles` and override `OS` when you call `make`. Note that those platforms aren't all well tested. Please open an issue in the tracker if you notice a platform not working. To compile in Windows with MS Visual Studio 2019, you will need additional files. Please see [here](https://gist.github.com/hack-tramp/b19b7675670bb5463bb763c602b5bc05). ## Usage See [USAGE.md](USAGE.md). ## Change log See [CHANGELOG.md](CHANGELOG.md).
