Microchip provides a unique Software Framework for the UC3 microcontrollers composed of a library of C source code optimized by Microchip's software engineers to make full use of the 32-bit AVR instruction set and architecture. The Software Framework contains low level peripheral drivers and math libraries, as well as high level communication stacks and application software including audio decoders, picture, TCP/IP services, file systems and even a full real time operating system. Full reference applications, like audio players, are built into the framework that utilize the drivers and services. The UC3 Software Framework is available for free and is designed specifically to reduce time to market for designs built around the AVR microcontrollers. The Framework even comes integrated into the development environment with a user friendly wizard that helps select the drivers and components needed in an application. With these tools, designing audio applications is easy and straightforward.
