In summary, the Atmel Software Framework is a compilation of embedded software for Microchip flash MCUs: megaAVR®, AVR XMEGA, AVR UC3 and SAM devices. It has been designed to help develop and glue together the different components of a software design. It can easily integrate into an operating system (OS) or run as a stand-alone product. The ASF is included in Atmel Studio 6.
