So I’m using an XOR checksum to detect errors in the transfer between the SX and the PC. I always thought it was a reasonably strong checksum, even though it’s still an 8 bit checksum.
I found a neat article today here.
“The XOR checksum has the highest probability of undetected errors for all checksum algorithms in this study, and is not as effective as addition-based checksums for general purpose error detection uses.”
There were around 6 or 7 different checksums presented.
