Raspbery Pi --- PIC 18F458 (RS485 network)

[Californiajoe]

Hello everyone,
did someone try to use Raspbery Pi device to comunicate to PIC over RS485. Is this possible and what would be needed to do that?
I have a working RS485 network with master and 6 slaves which work just perfect but the problem is ROM and RAM space (not enough), so I would like to move with master from PIC to another device (Raspbery PI) without ROM and RAM space limits.

Regards, Vlado

Without problems.
Use USB->FTDI->RS485 transceiver and connect it directly to USB port of raspberry PI.
Then, use A,B and GND cables and connect to your PIC device which also has RS485->UART transceiver.
