About:
AVRA is a portable assembler for the Atmel AVR microcontroller family. It accepts assembly source files and produces object files, listing files, and Intel HEX files suitable for programming AVR microcontrollers. It serves as a command-line alternative to Atmel's AVRASM32, offering cross-platform compatibility.

Key Features:

Supports the complete AVR instruction set
Generates standard output formats (HEX, COFF, object files)
Cross-platform compatibility (Linux, macOS, Windows)
Includes macro support for reusable code
Provides detailed error and warning messages

Use Cases:

Developing firmware for custom AVR-based hardware projects
Educational purposes for learning assembly language on AVR architecture
Converting legacy AVR assembly projects for use on modern systems

Alternatives:

AVR-AS (GNU Assembler) – Part of the AVR-GCC toolchain; uses different syntax (requires .S files) and is often preferred when linking with C code.
AVRASM32 – The official proprietary assembler from Microchip/Atmel; AVRA provides a free, open-source, and cross-platform alternative.
