(pkgsrc) Makefile mef now takes maintainership (ok by wennmach@) patches/patch-doc_Makefile.in (added) Adding PATH at installation time for OBJCOPY = avr-objcopy etc. See comment on SUBST part in Makefile. (upstream from NEWS file) *** Changes in avr-libc-1.8.0: * Bugs fixed: [#17815] Configure does not honor --mandir option [#23234] Alternate interrupt macro [#24861] Interrupt documentation contains extra include [#32103] Support for Target-Triplets [#32419] Incorrect EEPROM size in header for ATxmega192A3 [#32650] Missing include in util/delay.h [#32675] power_all_enable/disable does not affect timer1 on ATmega164P [#32698] power.h has additional endif that will break the build [#32773] stdiodemo source code is broken [#32988] Internal compiler error: build_unary_op [#33130] twitest.c source code is broken [#33230] Sleep modes have incorrect names for ATtiny261/461/861 [#33238] Wrong _VECTORS_SIZE for mega8U2 et al [#33858] in avr/power.h, clock_prescale_set() not defined for mega328 [#33920] ICR1 incorrectly defined for tiny167 [#34047] missing math.h include in delay.h [#34514] misspelled in math.h [#35020] stdint.h: signed types need explicit "signed" [#35093] strlcat_P fails for some destinations [no-id] New names for CLKSTA/CLKSEL0/1 for AT90USB82/162 system when power_all_disable() is used [no-id] util/delay.h would not compile with -ffreestanding * New devices supported: * Contributed Patches: [#7531] Bad name of bit in TCCR0A : WGM0 instead of CTC0 for ATtinyX61 [#7362] iom16a.h: USART vectors inconsistently named for ATmega16A [#7226] ATMEGA8U2 Patches * Other changes: - The old prog_* typedefs are now deprecated, and are only included if requested by the user. This request is expressed by declaring the macro __PROG_TYPES_COMPAT__, either by a #define directive before including <avr/pgmspace.h>, or by a -D compiler option. - Optimized strlen_P, thanks to Jan Waclawek. Rename strlen_P to be __strlen_P and add new strlen_P inline function in header file that checks if value is a constant and known at compile time. If not, then the new inline function calls __strlen_P as normal. ----------------------------------------------- *** Changes in avr-libc-1.7.1: * Bugs fixed: (7 line) * New devices supported: ATTiny84a ATMega16HVB RevB ATMega32HVB RevB *** Changes in avr-libc-1.7.0: * Bugs fixed: ( 138 line) * Other changes: - Added 'avr35' architecture. - Function vfscanf() is rewriten. - EEPROM functions are rewriten. - Added support for XMEGA architectures. - The Postscript documentation build has been removed in favour of building only the PDF (and HTML and man page) versions. - A sleeping BOD API was added to <avr/sleep.h>. - The note about signbit() implementation is removed from documenatation. - Signature API added in <avr/signature.h>. - All functions are now placed in the .text.avr-libc section, and the floating point functions are placed in the .text.avr-libc.fplib section. - The port/pin assignments of the HD44780 LCD controller in the stdiodemo example can now be distributed across more than a single AVR port. - Added support for avrtiny10 architecture, to support the ATtiny10 Family. - Added new headerfile: <avr/cpufunc.h>; currently contains _NOP() and _MemoryBarrier(). - The twidemo can now optionally address 24C32 and larger EEPROMs that require 16-bit word addressing. - Add a "memory barrier" to the cli() and sei() macros. * New devices supported: (76) * Optimized functions: (13) * New functions: (30)

This is avr-libc. It is a C library implementation for use
|
|
with GNU GCC and GNU binutils for development of programs for
|
|
Atmel's AVR microcontrollers.
|
|
|
|
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.
|
|
|
|
