ADXL345 no response

Hi,

I am using a evaluation board that consists of adxl345 accelerometer that comes along with aduc7024. The evaluation board is EVAL-ADXL345Z-DB.

I am trying to trigger a free fall interrupt but it seems like no response from the adxl345 after the settings are set.

The thresh_ff and also the time_ff is set through the i2c but there is still response from the adxl345. There is no interrupt triggering the aduc7024.

Is there any setting that i am not aware of? Frankly, I am very new into using analog device microcontroller.

 

 

The coding is attached.

 

Hope someone can help.

 

Thanks!

 

Regards,

Nicky
