Hi! When trying to communicate between an arduino Duemilanove (328p) and the compass module HMC6352 from sparkfun using the code provided under http://www.arduino.cc/playground/Learning/Hmc6352
, the program gets stuck at the line
after having sent the «command» 'A' and no matter how long I wait, I don't get a response from the compass.
I connected the module as indicated in the above example (GND,3.3V,SDA-->A4,SCL-->A5) and tried with and without pullup resistors on the SDA and SCL-lines.
Do you have an idea, where the problem might be?
Thank you very much. Dani
