There seem to be many published CRC16 implementations available. For
example (Arduino) http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1279505626

</div>Thank you for the pointers p4trykx. I've seen these two implementations<br>
before (the first one was announced by its author in this mailing list<br>
before I joined, but I read the mailing list archives). They are indeed<br>
good references although I wrote my own 1-Wire implementation from<br>
scratch since I felt these two did not fit too well with the other<br>
things I needed my own device to do.<br>
<br>
Cheers,<br>
