Re: RS485 - XPL on the wire

["g8kmh" <lehane@xxxxxxxxxxxxxxxxxxx>]

OK,
I'd missed xpl_devcom in my searches, oops!

LRC-8 is a simple checksum on the message. XOR everything after STX
including ETX and the result is the checksum. No big deal to do and
offers some protection against message corruption, which since the
RS485 is going to be around mains cabling (even taking into account
normal separations) I think is a reasonable precaution.

Be interested in the PIC implementations....

Thanks,
Lehane
