Oh yeah I remember now...you want to talk between two similar
devices, and that's what makes your application unique. Sorry that's
all I know about the subject for now. The circuit I showed has been
tested on bread board and is currently being designed into a product.
I hope to do some more experimenting with the finnished article,
maybe see if it will link to another micro device using the MCP2155.
