   A bit of theory...
   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

   A bit of practice...
   Assignment 1 – simple application
   • SAMD21 Xplained Pro board + 2 extensions
   • All support in ASF (boards, drivers, components, services)
   • simple: reading sensor data – displaying text

   Assignment 2 – changing of the board
   • SAMD21 Xplained Pro board replaced with Arduino Zero
   • SAMD21J18A replaced with SAMD21G18A
   • No ASF support for the board

   Assignment 3 – now component
   • Arduino Zero stays
   • Assume no SSD1306 display controller
   • We will learn how to add new features
