The Atmel Software Framework (ASF) is a library of source code which provides drivers, protocols, stacks, coding utilities, build system, etc. to a developer. The library demonstrates how to use the different functionalities of the Atmel devices.

ASF supports megaAVR®, AVR XMEGA® , AVR UC3 and SAM devices. The features available for the devices depend on the nature of each microcontroller family. ASF will provide the user with examples for drivers, services and components.

The software framework has been developed to help users glue together different components into a final application. It has also been designed to operate in a stand-alone fashion.
