SV: [AVR-Chat] communication b/n many controllers

Hi Mago

 

You may take a look at Modbus

http://www.modbus.org/specs.php

Download 'Modbus Protocol specification' and 'Modbus Serial Line Protocol and Implementation Guide V1.02'

This will give you an idea on how to do 1 master and many slaves over RS485 lines, by only addressing the slaves.

 

Svenn :-)

Hello guys

my master controller is going to use one UART to communicate with 18 
slave controllers. i use i/o control lines to avoid corruption. My 
question is that is this method reliable? Is there no effect of the 17 
others connected to the line when one is communicating to the master? 
any idea?

regards

mago
