CrossWorks for AVR is a complete C development system for Atmel AVR 8-bit microcontrollers that runs on Windows, Mac OS, Linux, and Solaris.

C compiler

CrossWorks C is a faithful implementation of the ANSI and ISO standards for the programming language C. We have added some extensions that enhance usability in a microcontroller environment.

CrossWorks C Library

CrossWorks for AVR has its own royalty-free ANSI and ISO C compliant C library that has been specifically designed for use within embedded systems.

CrossStudio IDE

CrossWorks for AVR is a streamlined integrated development environment for building, testing, and deploying your applications. CrossStudio provides:

• Source Code Editor:  A powerful source code editor with multi-level undo and redo, makes editing your code a breeze.
• Project System:  A complete project system organizes your source code and build rules.
• Build System:  With a single key press you can build all your applications in a solution, ready for them to be loaded onto a target microcontroller.
• Debugger and Flash Programming:  You can download your programs directly into Flash and debug them seamlessly from within the IDE using a wide range of target interfaces.
• Help system:  The built-in help system provides context-sensitive help and a complete reference to the CrossStudio IDE and tools.
• Core Simulator:  As well as providing cross-compilation technology, CrossWorks provides a PC-based fully functional simulation of the target microcontroller core so you can debug parts of your application without waiting for hardware.
• Utilities:  A set of tools for generating output files in multiple formats and a command line facility for flashing your applications onto the target board provide the final stage of the software development system.
