#183530 - One byte Responding to: ???'s previous message |
I would prefer to only have one byte in each message - the first - having the ninth bit set.
One problem with the ninth bit set in the checksum, is that the checksum byte can look identical to the address of a slave, falsely look like the start of a message. It's much easier to follow the address byte with a command + length - unless length can be always be deduced from the command numbers, in which case there isn't a need for any length byte. |
