Atmel Software Framework
Peripheral Drivers, Components and Services - With FreeRTOS Integration
Introduction

Watch the ASF Video.
The Atmel Software
Framework is a free and comprehensive package of drivers,
components, services, utilities and example projects. Many of the
example projects use FreeRTOS.
Each peripheral driver is cross referenced to applicable Atmel
microcontrollers and development boards, allowing the ASF Wizard
included in Atmel Studio to down
select from the available drivers to only display the drivers relevant to the
hardware in use. The
step by step workflow example provides more
detail, and demonstrates
how the ASF and the ASF wizard fit into a fully integrated development process.
