http://www.metools.info/encoding/ecod148.html WebMay 5, 2024 · I've got a problem calculating a checksum for a number of bytes (11, to be exact). Just as used in NMEA, I want to take the XOR of all those bytes and use that as the final byte. The function I'm using is: for (XOR = 0, i = 0; i < strlen (string); i++) {. c = (unsigned char)string [i]; XOR ^= c; } It calculates a value, but it never seems to be ...

WebNov 15, 2010 · Most likely is character based XOR. You'll need to get samples of them to verify but most checksums usually end up at 0. So, for an XOR checksum, you would have the packet: Bob,001X. where X is the checksum and, when you XOR all those characters together, you'd most likely get 0. So, to work out X, you just XOR all the characters in …
