    Default Help with PBP CRC-code for DS1820

    Hi!
    Have to test this new forum...

    I'm quite new to PIC:s, and are now playing with a 16f84 and a DS1820 tempsensor.
    Can anybody help me with some code exampels how I do the CRC-check.
    All PBP-code with a 1820 I found on the net, so far, just ignore the CRC...

    Thanks for some help!

    Default CRC-check for DS1820

    Anders,

    I just ran across this posting on the PICList regarding CRC for Dallas/Maxim devices:

    http://www.dattalo.com/technical/software/pic/crc_8.asm

    It's done in ASM but it may provide some clues or help you along the learning curve.

    Anders and Andrew, give me an email address to my address below and I'll send you crc.zip, which contains 3 different subroutines for computing crcs under PicBasic.

    This code was posted by a member of the mainstream PicBasic list.
