Hi. I'm having a weird problem with the UNO and a Sensirion humidity/temp sensor. Using the SimpleSensirion sketch included in the Arduino environment, the sensor works fine with the Diecimila (when I use a 10 k pullup resistor on the data line).
When I move the connections from the Diecimila to the UNO, I only get zeroes for the output (although it still prints the same words - temperature, humidity, dew point). If I move it back to the Diecimila, it's fine. I changed the board type when programming each, so I don't think that's it. Also, since it is printing the words correctly, some of the simpler problems would presumably be ruled out (serial communication, etc).
Has anyone else seen this, or successfully used the SimpleSensirion sketch with a UNO?
