> I see now the algorithm, but can;t seem to grok the a001 The a001 defines the feedback for the delay line. The way to represent the CRC would be something like: _________________________________ | __ __ | __ __ | __ | | | | | | | | | | | | | Din >--X-+->|D |--->|D |-X->|D |- .. >|D |-X->|D |->. | |__| |__| |__| |__| |__| | | 8000 4000 2000 0002 0001 | |____________________________________________| Where X depicts XOR and + is just a connection. The constant 0xa001 defines the feedback connections. > CRC code must only generate a 16 bit number with the low bit of both > bytes off. So XXXXXXX0YYYYYYY0. Very strange. Should not be. Maybe you are misunderstanding something in the code? -Pasi -- /Light, she loved Elayne almost as much as Rand - maybe as much, in a very different way - but how was a woman to compete with a beautiful golden-haired queen who had a powerful nation at her back and call?/ -- Min in The Wheel of Time:"The Path of Daggers" Message was sent through the cbm-hackers mailing list
