CodeVisionAVR is the only Integrated Development Environment on the market that features an Automatic Program Generator (CodeWizardAVR) for the new XMEGA devices.


Now with an enhanced CodeWizard, the new LCD Vision 1.03 Font & Image Editor/Converter (Advanced version only !) and Graphic LCD Libraries for the XG8800 and many more common LCD drivers.

LCD Vision

The compiler is supplied with many examples, including Graphic LCDs, SD/MMC Card FAT, XMEGA ADC, DAC, TWI, 1 Wire, EBI and the ports of Atmel’s Application Notes AVR1300 “Using the XMEGA ADC”,  AVR1605 “XMEGA Boot Loader”, AVR270 “USB Mouse”, AVR272 “CDC Demo UART to USB Bridge”, Wiznet W5100 web server.

The popular FreeRTOS is now ported to CodeVisionAVR.

  • Application that runs under Windows® XP, Vista, Windows 7 and Windos 8, 32bit and 64bit
  • Easy to use Integrated Development Environment and ANSI C compatible Compiler
  • Editor with auto indentation, syntax highlighting for both C and AVR assembler, function parameters and structure/union members autocomplete
  • Besides it’s own IDE, CodeVisionAVR can be used an Extension integrated in Atmel Studio 6.1 or later
  • Supported data types: bit, bool, char, int, short, long, float
  • Fast floating point library with hardware multiplier and enhanced core instructions support for all the new ATmega chips
  • AVR specific extensions for:
    • Transparent, easy accessing the EEPROM & FLASH memory areas, without the need of special functions like in other AVR compilers
    • Bit level access to I/O registers
    • Interrupt support
    • Support for placing bit variables in the General Purpose I/O Registers (GPIOR) available in the new chips (ATtiny2313, ATmega48/88/168, ATmega165/169/325/3250/329/3290/645/6450/649/6490, ATmega1280/1281/2560/2561/640, ATmega406 and others)
  • Compiler optimizations:
    • Peephole optimizer
    • Advanced variables to register allocator, allows very efficient use of the AVR architecture
    • Common Block Subroutine Packing (what our competition calls “Code Compressor”), replaces repetitive code sequences with calls to subroutines. This optimizer is available as Standard in CodeVisionAVR, at no additional costs, not like in our competitor’s products.
    • Common sub-expression elimination
    • Loop optimization
    • Branch optimization
    • Subroutine call optimization
    • Cross-jumping optimization
    • Constant folding
    • Constant literal strings merging
    • Store-copy optimization
    • Dead code removing optimization
    • 4 memory models: TINY (8 bit data pointers for chips with up to 256 bytes of RAM), SMALL (16 bit data pointers for chips with more than 256 bytes of RAM), MEDIUM (for chips with 128k of FLASH) and LARGE (for chips with 256k or more FLASH). The MEDIUM and LARGE memory models allow full FLASH addressing for chips like ATmega128, ATmega1280, ATmega2560, etc, the compiler handling the RAMPZ register totally transparently for the programmer. This feature is available as Standard in CodeVisionAVR, at no additional costs, not like in our competitor’s products.
    • User selectable optimization for code Size or Speed
  • Possibility to insert inline assembler code directly in the C source file
  • VERY EFFICIENT USE OF RAM: Constant character strings are stored only in FLASH memory and aren't copied to RAM and accessed from there, like in other compilers for the AVR
  • C Source level debugging, with COFF symbol file generation, allows variable watching (including structures and unions) in Atmel Studio 6.1 and AVR Studio 4.19 debuggers
  • Fully compatible with Atmel’s In-Circuit Emulators: AVR JTAG-ICE, AVR Dragon, etc.

CodeVisionAVR User Manual

Please create a BACKUP copy of the downloaded setup file on a secure media.

CodeVisionAVR V3 is designed to be used both in its own IDE and also as an Extension in Atmel Studio 6.1 or later version.
It is compatible with Windows® XP, Vista, Windows 7 and Windows 8, 32 and 64-bit operating systems.
For the Extension to be installed correctly, Atmel Studio 6.1 must be already present on the computer, before the CodeVisionAVR installer is launched.
Important Notes:
  • When installing and using Atmel Studio and CodeVisionAVR, the user must be logged in as Administrator in Windows.
  • During Atmel Studio installation under Windows XP, the checkbox Protect my computer and data from unauthorized program activity must be unchecked.
  • If the older AVR Studio 5 or Atmel Studio 6.0 are present on the computer, they must be first fully uninstalled before installing Atmel Studio 6.1 and CodeVisionAVR.
  • The Naggy extension for Atmel Studio is not compatible with CodeVisionAVR.
    When using CodeVisionAVR, Naggy must be disabled from the Atmel Studio's menu: Tools|Disable Naggy.
After Atmel Studio has been installed, you may unzip the downloaded file in a temporary directory and launch the CodeVisionAVR installer.
Note: When installing CodeVisionAVR under Windows Vista, the User Account Control must be disabled, as outlined in the instructions.

CodeVisionAVR can be also used with its own IDE and the AVR Studio 4.19 debugger, without having to install Atmel Studio.
This may be useful if the user wants to preserve disk space or has a slower computer.

Some users may wish to install both Atmel Studio 6.1 and AVR Studio 4.19 on the same computer.
In this case the debugger to be used can be selected in the Settings|Debugger menu of the CodeVisionAVR IDE.

Details about using CodeVisionAVR with these debuggers are available in the Help topics:
  • Using the CodeVisionAVR Extension for Atmel Studio
  • CodeVisionAVR C Compiler Reference|Using the AVR Studio 4.19 Debugger
and in the chapters: 1 and 4.21 of the CodeVisionAVR User Manual.
