I am having problems getting the SHT15 to communicate with a pro mini 5v. All the code works with the mini but not the pro mini. I have tried a few examples using code off the web:

http://www.flatline.net/journal/2008/04/11/arduino-reading-the-sht15-temperaturehumidity-sensor/
- returns limits (h: 0 and temp: -40) implying no communication

http://ragingreality.blogspot.com/2008/01/ardunio-and-sht15.html
- hangs

http://www.glacialwanderer.com/hobbyrobotics/?p=5
- returns ACK error 1

Has anyone had similar difficulties? solutions?

thanks, don
