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. WWW: http://savannah.nongnu.org/projects/avr-libc
