avr-libc -- a C and math library for the Atmel AVR controller family
This library implements a subset of common C library functions, some
Atmel AVR specific additions (like handling AVR's IO facilities,
EEPROM etc.), as well as a 32-bit floating point math library (-lm).
Everything is designed and implemented to cooperate with avr-gcc and
avr-binutils.
Please note that this is currently work-in-progress. Documentation
is becoming embedded into the source code which will hopefully get
it more complete and up-to-date. Some parts of the current library
have proven to be not all that useful (e. g. timer_enable_int())
so they might be removed in a future version.
The port is currently taken from the avr-libc-1_0-branch which will
eventually become version 1.0.
