Hello,

I do not understand why my LIS2DH stays at 188uA (basically the one in boot-up configuration) even if I configured it in Low-Power mode ?

Here is my configuration :

--LIS2DH Config---
CTRL_REG1 : 0x2F (ODR 10HZ / Low Power / All Axis enabled)
CTRL_REG2 : 0x0E (HP filter activated normal mode)
CTRL_REG3 : 0x00
CTRL_REG4 : 0x80 (BDU / scale 2G / High Res disabled)
CTRL_REG5 : 0x42 ( Fifo enable / INt2 enable)
CTRL_REG6 : 0x00
STATUS_REG : 0xFF
FIFO_CTRL_REG : 0x80
FIFO_SRC_REG : 0x20
INT1_CFG : 0x00
INT1_THS : 0x00
INT2_CFG : 0x2A
INT2_THS : 0x06
INT1_SRC : 0x00
INT2_SRC : 0x00

 

Help welcome.
