![]() ![]() Therefore I decided to write this article, trying to cover all topics I had difficulties with. This article is the result of the fact that I found finally time to deal with CRC.Īfter reading Wikipedia and some other articles, I had the feeling to not really understand completely in depth. 8.6 When using an initial value other than zero in the shift register, the result is incorrect.Īrticle updated March 2019 (for details, click here to see the changelog).8.5 Why does multiplication with x n append n zeros?.8.4 Why is addition is the same as subtraction in CRC arithmetic?.Additional remarks (points worth to know) 7.3.1 Reversed CRC lookup table and calculation of reciprocal CRC.7.2 Representation of generator polyonomials.4.4 Improved CRC-8 byte-by-byte algorithm (lookup table based).4.3 General CRC-8 bitwise implementation.4.2 Modified CRC-8 bitwise implementation for one byte input data. ![]() 4.1 Simple CRC-8 shift register implementation for one byte input data.
