AVR UC3 Software Framework
:

The UC3 Software framework provides software drivers and libraries to build any application for AVR32 UC3 devices. It has been designed to help develop and glue together the different components of a software design, and to be easily integrable into an operating system (OS) as well as to operate in a stand-alone way.

  • Drivers for each AVR32 UC3 peripheral
  • Software libraries optimized for AVR32
  • Hardware components drivers
  • Demo applications that use all libraries
  • RTOS-ready source code
  • Complete software framework in C code
  • Full projects compatible with GNU GCC and IAR Embedded Workbench
  • High level user documentation including examples, getting started and tutorials
  • Designed to run on AVR32 UC3 evaluation kits and easily portable to any other hardware platform


    • The UC3 SW Framework is also included in AVR32 Studio. No separate download is required.
