Library of C Source Code
The AVR UC3 Software Framework is a collection of
production-ready source code written and optimized
by Atmel application experts and tested in hundreds
of production designs. Using these peripheral drivers,
communication stacks and application-specific libraries
is the quick and effortless way to release the superior
AVR performance. The AVR UC3 Software Framework
supports all 32-bit AVR devices and development kits
and is compatible with both AVR GNU Toolchain and IAR
Embedded Workbench
®
compilers.
Drivers
Peripheral and CPU Drivers
A complete set of CPU and Peripheral drivers hide any device specific peripheral features below a
standard set of Application Peripheral Interfaces (API) function calls to makes the migration between AVR
devices quick and easy. Peripheral drivers include code used to initialize and service the clock system,
I/O multiplexing, peripheral interrupts, DMA transfers and Peripheral Event System connections.

External Peripherals
The AVR UC3 Software Framework contains drivers for popular off-chip components such as QTouch
®
capacitive touch keyboards, LCD displays, SRAM/SDRAM/NAND Flash memories, SD/MMC storage
cards, and audio amplifiers/codecs.
Boards
Hardware Abstraction Layer
To simplify the process of writing code for a specific
hardware board, the AVR UC3 Software Framework uses
a Boards layer to describe the external hardware and
configure the board specific multiplexing of peripheral
functions through the AVR I/O pins. Replacing pin num-
bers by more logical names when addressing external
hardware makes the source code easier to read, and also
simplifies the process of migrating a project from one
board to another.
