Calling wire.begin(x) from inside the interrupt of the transmission from the Master seemed to work fine.
Very nice work.Implementing this on the 24x8 LCD's I have would be very cool.This is where I got a couple from. They accept TTL level Serial or RS232 Level Serial, @ 19200 baud.http://cgi.ebay.com/Intel-8032-Single-Board-Controller-Serial-24-x-8-LCD-/120726684894?pt=LH_DefaultDomain_0&hash=item1c1bdf04deI have about 6 of them. They were $15 at the time when got them.
@liudr...Unfortunately I only have room for 4 buttons, is it still a goer without the extra two?...______Rob
I wonder if you could make up the last two buttons "logically" with a "chording" of some combination of other buttons...
