roskenet / avr-libc

The AVR Libc package provides a subset of the standard C library for AVR 8-bit RISC microcontrollers.

AVR LibC

This is the standard library for Atmel AVR devices together with the AVR-GCC compiler.

The library contains most of the functionality required by the ISO C standard, with the notable exception of wchar_t support. It also contains a lot of auxiliary functionality targeted to the AVR controller family. Further, it includes customizable startup code, tailored to work together with the linker scripts provided by the GNU binutils, so for most AVR applications, there is usually no need to provide project-specific files for that purpose.

See the documentation for details.

The library is distributed using a modified BSD-style license.
