|WINAVR is (or was) a great project. Its most “recent” package is from 2010-01-20. In other words, it is outdated. There are many projects that attempted to replace it but none of them (AFAIK) is extremely popular. We’ve put together a very detailed guide on how to setup everything manually – AVR GCC Toolchain – Setup for Windows.|
WinAVR is a great tool to do development for Atmel AVR micro-controllers on Microsoft Windows platform. It consists of all the necessary C/C++ compiler, linkers and other GCC tools that you need to write, build and program those micro-controllers.
The guide was tested mostly under Microsoft Windows 8.1 operating system.
The example source code was tested on ATtiny85 microcontroller installed on Tinusaur project boards and programmed using USBasp ISP programmer.
