Yep, BHogan TinyWireS lib as documented above in Reply #28.
Thanks.
Have you had any problems with it? Made any changes? Thought of any enhancements you'd like added?
just to add a basic support i've changed the 2313 ifdefinitions like this:
if defined( AVR_ATtiny2313 ) || defined( AVR_ATtiny4313 )
Got it. Thanks.
I added a request to the issue list...
