Hello to all, this is my first post here...
I'm gently asking if someone could help me trying to discover what's the matter with sensor and protocol stated in the title.
I bought the BMP085 from Drotek (FR) but it's like the one from Sparkfun, with the only difference of smaller delivery time for me living in Italy.
During last week I made several tests, and the sensor initially worked almost good, but after being working for about two hours it doesn't work anymore.
I premit that it has been plugged correctly, correct 3.3V supply, correct A4 & A5 plugging of I2C interface on my Arduino Uno board. When the sensor didn't work I tried to make it send parameters to a LCD screen directly plugged on my own shield and/or to COM port, I tried to supply with USB, 9V battery and both two, but got no answer.
After keeping Arduino unplugged for many hours, the sensor will work for 2-4 seconds and then still no answer, even if pushing reset button on the board
Pease could any of you tell me if this could be caused by I2C protocol (Arduino board failure) or if ti could be imputable to a misfunctioning of the BMP085 sensor? Is there any method to check it, considering that's my only I2C-based sensor?
