Peace be to all,
I am working on interfacing 14 slave controllers to a master via RS485 (full duplex). The querry is that which IC to use and the schematic of TTL to RS485 (full duplex) converter to interface b/w avr and RS485.
thanking in anticipation
If thats the only option you got you could use 2 MAX485 to build 1 FullDuplex tranceiver. Just use one as receiver grounding both flow control pins (DE and RE) and just using the RO Pin. The other one you use as a sender, driving both flow control pins to 5v and just using DI pin to send data. You going to have a FullDuplex tranceiver, but you going to have to use 2 MAX485 for each node on the bus.
