Sorry about the mis-titled post before, so here's my question properly titled... I can figure out how electrically wire up I2C devices easily, but the thing that I don't wholly understand, is the addressing of the slave devices. I mean how do I know what address my certain device uses? Is there something that i need to program beforehand or what? Any help/nudges in the proper direction(s) would be most helpful Sincerely, Jonathan Herr (dracosilv) -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
