We need to support the xmega users better. If they're getting easily confused, then we need to help.
It took me a while to discover that the Xmega "CCITT" wasn't the same as the avr-libc function, and yes, the difference between _xmodem and _ccitt isn't all that well described (esp if/since they're actually inverse of each other polynomial-wise). Plenty of trouble finding the right Python code to insert into my passive bus sniffer too. Not looking forward to figuring out CRC-32 re: the NVM, the CRC module, and python. That *should* be easier since they claim it's 802.3 and afaik crc32 is quite a bit more standardized, but...
The key for me was finding this page: <http://www.lammertbies.nl/comm/info/crc-calculation.html> _______________________________________________ AVR-libc-dev mailing list AVR-libc-dev@nongnu.org https://lists.nongnu.org/mailman/listinfo/avr-libc-dev
