I need resourceful information's on how to implement the serial protocol via an RS485 interface. As regards to my area of application, I simple want to communicate with my micro-controller via an RS485 port. How do I go about this? Any useful links with useful steps will be appreciated.
I am designing an energy meter with interfaces in-other for it to communicate with the outside world, to READ and WRITE informations. I intend to add to it the RS485 interface just like the Optical communication interface which I have already implemented. I want to know if there is anyway I can combine the serial protocol communicating via the RS485 interface. I hope this is more clearer.
