Sorry Jungs und Mädels, nach der vielen Arbeit der letzten Tage habe ich gerade keinen Nerv, das auch noch alles ins Deutsche zu übersetzen. Falls einer was nicht versteht, kann er gern fragen... Triggered by the impending release of FreeBSD 6.3 and 7.0 (yes, they prepare a stable and a bleeding edge release almost in parallel), most of the AVR opensource tools have got new releases as well. In detail this is: avr-libc-126.96.36.19971029 ======================= This is a "sneak preview" of the avr-libc development tree. Its primary intention is to provide some kind of public gamma testing for the new features in it. In no particular order, the list of new things includes: . A completely rewritten floating-point library, contributed by Dmitry Xmelkov. It is smaller and faster, but as it's an almost full rewrite, this triggered the intention to prepare a public release from the development source code base. . A rewritten and much extended <avr/interrupt.h>, contributed by Dean Camera. This re-introduces the availability for a macro that can be used to declare an ISR that starts with interrupts initially enabled, but also simplifies declaring "naked" ISRs, and includes ISR aliasing features as well. The older ISR_ALIAS() macro has been deprecated in favour of the ISR_ALIASOF() attribute to the rewritten ISR() macro. . An <util/setbaud.h> helper file, contributed by Cliff Lawson and Carlos Lamas. The idea behind that file is to provide a simple preprocessor logic for the calculation of AVR baud rate prescaler values, which also includes a check against a pre-defined acceptable baud-rate tolerance (2 % by default), and also automatically suggesting the use of the U2X bit when it's necessary in order to achieve the baud-rate tolerance. . An <util/atomic.h>, also contributed by Dean Camera. This offers a nice wrapper to make certain brace-blocks in an application atomic with respect to being not interrupted. So please test it, folks! By its time, the code base that can be seen there will eventually become release 1.6.0, forming a new stable release line. avr-libc 1.4.7 ============== This is the current release of avr-libc from the stable branch. Please see the NEWS file for a list of changes, compared to 1.4.6: http://www.nongnu.org/avr-libc/NEWS.txt AVRDUDE 5.5 =========== . Add support for the USBtinyISP programmer (patch #6233) . Add support for the C2N232I serial bitbang programmer (patch #6121) . Bugfixes. AVaRICE 2.7 =========== New CPU support added: ---------------------- . AT90PWM2B/AT90PWM3B (same as AT90PWM2/3 but different signature) . ATmega325/3250/645/6450 New features added: ------------------- . Software breakpoints are now also supported when using JTAG. Summary of important bug fixes: ------------------------------- . Complete overhaul of the USB communication, making it much more robust, and less resource-consuming. . DebugWire bug fix submittted by Shaun Jackman. FreeBSD ports/patches ===================== The FreeBSD ports of avr-binutils and avr-gcc have been updated to binutils 2.18, and GCC 4.2.2, respectively. This includes updating the patches contained therein, which are apparently used by others as reference for own porting efforts. I'd like to thank everyone who contributed to these efforts! Thank you, merci, gracias, danke schoen, mange tak, spasibo bolshoye!
