8-bit CRC algorithm

[naga2403]

Hello,

I am working on sending data that uses 8bit CRC algorithm. I am using the algorithm from https://forums.ni.com/t5/LabVIEW/Computing-CRC/m-p/825331/highlight/true#M375052. It uses the polynomial 0x31(x^8+x^5+x^4+1), initial value xFF. I have trouble getting the expected data mentioned in the example, CRC(0x00) --> 0xAC.

Any advices.

Thanks.

Rather than spending hours debugging your VI, here is one that works. I've used it for many, many years and I can't remember where I got it to properly acknowledge the original author.

Thank you @jamiva for sharing the algorithm.
