Hello, I need to implement a small network consisting of one master and up to 16 slaves. I have decided that RS-485 is a good physical level protocol to use, but im wondering about the software side. Right now i am thinking about using the UART on my micro controller hooked to a full duplex RS-485 driver (MAX489). Then it seems that i could use the 9-bit capability of the UART to send address bytes and data bytes. Does anyone have any links on the best way to do this, or things to look out for?
