Integrated Development Environment for the 8-bit Atmel AVR and XMEGA Microcontrollers
Download
CodeVisionAVR V3 is designed to be used both in its own IDE and also as an Extension in Atmel Studio 7 or the older 6.2.1563.
It is compatible with Windows® XP, Vista, 7, 8 and 10, 32 and 64-bit operating systems.
For the Extension to be installed correctly, Atmel Studio 6.2.1563 or 7 must be already present on the computer, before the CodeVisionAVR installer is launched.
Important Notes:
Setup Instructions
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.
When installing and using Atmel Studio and CodeVisionAVR, the user must be logged in as Administrator in Windows.
When installing CodeVisionAVR under Windows 8 and 8.1, please right click on the CodeVisionAVR, LCD Vision and Atmel Studio icons on the desktop, select Properties|Advanced and enable the Run as Administrator option
During Atmel Studio installation under Windows XP, the checkbox Protect my computer and data from unauthorized program activity must be unchecked.
If the older Atmel Studio 6.0 or 6.1 is present on the computer, it must be first fully uninstalled before installing Atmel Studio 6.2.1563 or 7 and CodeVisionAVR.
After uninstalling the old Atmel Studio, the remaining C:\Program Files (x86)\Atmel\Atmel Studio 6.x directory and files must be deleted.
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 7 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:
Free, 4kbytes code size limited version. Includes also the
