My customer use ADXL345 and they have some issues.
They are using I2C interface to communicate with ADXL345.
The issue is that they can get normal data of ADXL345 normally, but suddenly some time they got Zero values (X=0,Y=0,Z=0).
At this time, when they cahek I2C Data using Osciloscope, there are no data in I2C.
And also SCL and INT1 are HIGH and SDA is LOW.
3.3V is supplied to VDDIO and VS.
Would you confirm this issue and let me know your all opinions about this issue?
(They say that it is very hard to reproduce this issue.)
Please advise me.
If you have any questions, please let me know.
