I just tested this with Arduino 1.0.1 works like a charm.
@Globe
You state you use Arduino 1.0.1. Can you explain why you get
/Applications/Arduino1.app/Contents/Resources/Java/libraries/Wire/utility/twi.h:45: error: previous declaration of 'twi_readFrom' was here
When twi_readFrom is declared on line 43 with me in Arduino 1.0.1?
Best regards
