1 Getting Started with Atmel Studio
1.1 Download and Install Atmel Studio 6.2
Atmel Studio 6 is the integrated development platform (IDP) for developing and debugging Atmel ARM®
Cortex®-M and Atmel AVR®microcontroller (MCU) based applications. The Atmel Studio 6 IDP gives you a
seamless and easy-to-use environment to write, build, and debug your applications written in C/C++ or
assembly code.
Atmel Studio 6.2 is now available, adding advanced debugging features such as Data and Interrupt Trace,
improved RTOS integration, and better ability to debug code that has been optimized.
With the introduction of Atmel Gallery and Atmel Spaces, Atmel Studio 6 further simplifies embedded MCU
designs to reduce development time and cost. Atmel Gallery is an online apps store for development tools and
embedded software. Atmel Spaces is a cloud-based collaborative development workspace allowing you to host
software and hardware projects targeting Atmel MCUs.
Download and install Atmel Studio 6.2 from http://www.atmel.com/microsite/atmel_studio6/.
You can find the installed directory: C:\Program Files\Atmel\Atmel Studio 6.2.
1.2 Download and Install the latest ASF
Atmel Studio 6 is free of charge and is integrated with the Atmel Software Framework (ASF) —a large library
of free source code with 1,600 ARM and AVR project examples. ASF strengthens the IDP by providing, in the
same environment, access to ready-to-use code that minimizes much of the low-level design required for
projects. Use the IDP for our wide variety of AVR and ARM Cortex-M processor-based MCUs, including our
broadened portfolio of Atmel SAM3 ARM Cortex-M3 and M4 Flash devices.
If the ASF version in your Atmel Studio is not the latest one you will be notified when Atmel Studio starts. The
following procedure demonstrates how to update the ASF to the latest version. You can install other extensions
in the list as well.
