Ah, figured it out. SDA and SDC can be accessed directly on the Mega with pins 20 and 21. Just needed some short leads and it works perfectly on both boards now.
This all works fine on my duemilanove/328 but when I try it on my Mega/ADK with the same sketch and same shield, the humidity, temperature and pressure are wacky. Do I need to change something in the i2C setup in the sketch for the Mega? These readings are what I get and they don’t change: humidity=998.0,tempf=-1766.2,pressure=-999.00
The suggestion below on using separate power makes no difference in my case.
No public wish lists :(
