Ciao !
it's possible to interfacing an Arduino (by MAX485) to a RS485 serial bus with a crc-16 control ??

thank's :-[

Yes, a properly wired MAX485 and with the right programming an Arduino can communicate on a RS-485 link. Not simple programming but maybe you can find some existing software library code to help you along.

CRC is not a control function, but rather an error detection method such that the the receiving node can either ignore the flawed message or ask for a retransmission of the flawed message.

thank's, !

I'm been able to create the program with VB6 ! now remains for me to translate it for ARDUINO!
