Can someone tell me how the CRC is calculated for the DS18S20 temperature sensors? I use the following line to receive the temperature and CRC but I'm not sure how to calculate the CRC to do a comparison.
owin portb.7, 0, [temp.byte0, temp.byte1,SKIP 6,crc]
Tom Estes posted two different Dallas 1-wire CRC routines here in the Code Examples forum.

Thanks to the link/info. This is exactly what I was looking for.
Thank you for the posts. I found where I was looking for. For those who want to know more about CRC read this article called: 'A painless guide to CRC error detection algorithms' http://www.geocities.com/SiliconVall...s/8659/crc.htm
