Hello ,everyone.
  Now, I have some prolem about LIS3DSH . I tried run "state machine" LIS3DSH presets WakeUp from AN3393 page 78, but anything I do, the  interrupt  occur on INT1 all the time. What is the Problem ?

These codes debug on my device:

printf("who am I ?.........    \r\n");
printf("I am LIS3DSH (0x%d )  \r\n",tmp);     
printf("I am ??? ~   \r\n");
