Dallas CRC8 Routines

[Tom Estes]

Using other 1wire devices I have been able to do the following:

' Read the next 32 bytes, calculate running CRC but discard the bytes
For Index = 1 to 32
OWIn OWPort, 0, [CRCData]
GoSub CRC
Next Index
OWIn OWPort,0,[DesiredData]
CRCData = DesiredData
GoSub CRC

In other words there may be enough time in between data bytes sent from the 1 wire device to calculate the CRC on a running basis. If you don't need all the data the CRC can be calculated and the data discarded, retaining only that data you need.

I was wondering if that would actually work or not. This is my final line. Again thanks for all your help.

    for x = 0 to 8
    owin portb.7,0,[i]
    dq[x] = i
    next x
