More than likely no.

You don't state which and I may not be familiar with the 1 wire device you are using but normally you would not be able to skip any characters it transmits. They would all need to be received and included in the CRC calculation. You will need to read the data sheet for the 1 wire device you are using to see what all is included in the CRC total.

To get that total feed each byte into the CRC routine, The CRC will be calculated and after all bytes that the manufacturer has included in the CRC total have been passed trough it, the CRC should be the same as the CRC received from the 1 wire device.
