AVR Toolchain Installation

Index

5. Install on Windows

  1. Download the latest Atmel AVR toolchain from the Atmel website. Be sure to choose Atmel AVR 8-bit Toolchain. At the time of writing, the current version is 3.5.0. You will be required to create a myAtmel account or register as a guest with a valid email address to get the download link.

  2. The installer is a self-extracting 7-Zip archive. When you run the installer, you will be asked where to extract the files. I recommend choosing C:\ as this will result in the toolchain being placed in C:\avr8-gnu-toolchain\

  3. Next, you will need to download AVRDUDE from the AVRDUDE download area. You should choose the latest mingw32 version (e.g. avrdude-6.2-mingw32.zip). At the time of writing, the current version is 6.2.

  4. Extract the zip file to a good location such as C:\avrdude\

  5. AVRDUDE depends on libusb to work. You can download the latest version of libusb for Windows from the libusb-win32 project download site. At the time of writing, the current version is 1.2.6.0.

  6. Extract libusb0_x86.dll and libusb0.sys to the same directory as AVRDUDE. These files are located in the libusb-win32-bin-1.2.6.0\bin\x86 folder within the zip file.

  7. Rename libusb0_x86.dll to libusb0.dll.

  8. Installation of the toolchain on Windows is now complete.
