We're a group of 4th year engineering students, and as our project we've gotta interface an embedded device with a 485 port via a wifi network to a master computer. there would be about 10 embedded devices which would be polled by the pc. now we've got the wifi card for the pc side, what do we put on the embedded device side? i know we've gotta put a microcontroller and some ROM, but i've got no clue about the wifi device needed. Any links or suggestions would be greatly appreciated.
