Cyclic Redundancy Check (CRC) Nightmares
By Robert Haller
This article is a continuation of SI/PI problems and lessons that I have toiled through and would love to share with the community. I received positive feedback on my last article Mysterious Case of the Flapping Switch, so I will continue to try to capture some interesting stories. Hopefully this will help others to quickly debug their lab nightmares.
