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:

 

LIS3DSH_GetWHO_AM_I(&tmp);

printf(''whoamI?.........\r\n'');

if(vtmp==0x3F)

printf(''IamLIS3DSH(0x%d)\r\n'',tmp);

else

printf(''Iam???~\r\n'');

LIS3DSH_WriteReg(0x21,0x01);

LIS3DSH_WriteReg(0x23,0x48);

LIS3DSH_WriteReg(0x20,0x67);

LIS3DSH_WriteReg(0x57,0x55);

LIS3DSH_WriteReg(0x59,0xFC);

LIS3DSH_WriteReg(0x5A,0xFC);

LIS3DSH_WriteReg(0x40,0x05);

LIS3DSH_WriteReg(0x41,0x11);
