WinAVR (tm) is a suite of executable, open source software development tools for the Atmel AVR series of RISC microprocessors hosted on the Windows platform. Includes the GNU GCC compiler for C and C++.
It had ruined my PATH variable, many programs stopped working. :( As I have already uninstalled the program, the PATH stored in path1.log was renamed to path2.log, updated with current (wrong) path and deleted. I have found some PATH in this registry: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Environment
This software is nice... Assuming you can get it to work for you. I read some of the reviews and I didn't want to take the risk of winavr overwriting my path directory, so I unchecked that option for the install. However, I couldn't use things like avrdude without changing the directory and running the executable. But, there is a work around that I want to share that could save someone a lot of time if they don't want to take a risk like me. Create a file called "winavr.bat" in "C:\WinAVR-20100110" with the following contents: set PATH=%PATH%;C:\WinAVR-20100110\bin;C:\WinAVR-20100110\utils\bin cmd If you want to use WinAVR, just simply double click on the .bat file and you'll be able to use avrdude, make, etc. I do not take credit for this. I would have just given the link, but I would never expect someone to click on a link in a review. Go to section 2.1.4 of this page: www.newae.com/sidechannel/cwdocs/installing.htmlokpoijoiu
