I'm quite convinced that the writing is working since the writing returns a 0 (no errors) for every adress I've tried but [A2:A0] = 001. So A2 and A1 is grounded while A0 is kept high.
So in my case my 8-bit adress, incl the r/w-bit, is 0x92 (writing) and 0x93(reading).
I was thinking it might be problem with the init, but I'm not exactly sure how it works. I'm also going to try if I can successfully write to the configuration register today. If that does not work, the sensor must be fried or something...
I can also add the the SCL and SDA lines are working since on the same PCB I've an EEPROM which works.
Check your speed.... EEPROM's work a 400khz (normally) but sensors may work at 100khz only... secondly what value resistors have you used for SDA and SCK lines....I use two devices and set them to 4k7
