The structure of the 3rd generation of ASF • Pinout and pinmux definitions • I/O initialization • ”schematic in code” • replace register-level code • configure peripheral modules • high-level functions to handle e.g.: - graphics - file systems • manage hardware external to MCU • similar to drivers • compiler abstraction layer • 1000’s of example applications • representation of user application AN-9684: Custom application support in ASF 10/10/2012
