Hi!

I am using the LIS331DLH sensor in my project. I have no problem with processing between CPU and sensor via SPI. But I cannot communicate them via I2C - all registers are return 00 when reading.

Here is the part of my code that describes W/R process of sensor, and oscillogramm of I2C bus.

Thanks.
