Welcome to my blog on Checksums and CRCs!
Over time I'll be posting articles related to checksums, cyclic redundancy codes, parity strategies, and their effectiveness. If you have a particular topic you'd like me to post on please let me know and I'll put it in the idea bin.
If you are looking for more general embedded system topics, please have a look at my Better Embedded Software Blog.

Why To Avoid Hash Algorithms If What You Really Need Is A Checksum
Sometimes we hear that someone plans to use a hash function for fault detection instead of a checksum. This is probably not the best idea, b...
