Hi ,
I was communicating with master slave concept for RS485.
If i communicate with the one master and one slave it is woking good .
But if i connect one master and two slaves , the second slave gets hanged, i.e display displays some wrong character.I had connected the second slave as only hardware(no query is sent to it from master).
The RS 485 ckt is a standard one which i got from net only. I will also attach it.
In the pdf page no 181 , the ckt is there. Here master is a 3.3 v PXA 270 processor (Embedded wince OS)and slaves are 5v 8051 microcontrollers .
I dont know where the problem is situated . Whether it is in hardware or software.
Pl help me . I am doing this for more than 1 month.
Very urgent
