Update of bug #37901 (project avr-libc):
Status: None => Invalid
Assigned to: None => joerg_wunsch
Open/Closed: Open => Closed
_______________________________________________________
Follow-up Comment #1:
The function you describe is provided by
_crc_xmodem_update() in <util/crc16.h>. It uses
the same polynomial as _crc_ccitt_update()
(x^16 + x^12 + x^5 + 1), but the opposite bit order.
_crc_ccitt_update() is known to work well together with
typical communication protocols that transmit the low-order
bit first, e.g. IEEE 802.15.4.
