crc

[Dustyboy]

Hi,

I`m struggling with CRC-8 calculation.

I need to make a VI out of picture  crc-8

When I`m trying with just 1 byte on datainput

it`s ok, but with 2-4 bytes it gives me wrong checksum.

 

Any ideas how to make this Vi work ok?

 

Thanks for any help,

You should have done some searching.  There are plenty of examples.  I posted this zip package that is actually based off the that exact website's javascript.

Hi,

Thanks for Your reply.

Even with Your CRC-8 check i do not get same result.

I get value C2  with same input as above but i need 13 as result.

Something i missed out?

Change CRC Calculation from CRC-8 to Other (specify).  The CRC Parameters cluster is only valid when you specify Other.  The CRC-8 is a built-in version which uses an initial value of 0x00.  You also need to set CRC order to 8.
