Low power mode on LSM330DLC

[AAliy]

Hi,

I'm using LSM330DLC on my board and I've configured low power mode (accelerometer enters the low power mode in case of inactivity, and goes back to normal mode if I touch/shake it). What I would like to know - if there is any way to know that accelerometer entered the low power mode? In that case I would like to put gyro and MCU into sleep mode and wake up on the interrupt from accelometer.

Also, maybe it's possible to configure the accelerometer to produce interrupt on when it enters the low power mode/normal mode?

Hi, sorry for our delay in the answer. There are some possible way to know the devices entered the low power mode: the current consumption is low, the output data are on 8bit instead of 12bit. However, I suggest you to use the “Sleep-to-wake�? and “Return to sleep�? feature: the I1_AOI1 in CTRL_REG3_A (22h) should go high after the event detection (that exceeds e.g. ACT_THS) and you can detect it by polling that register or physically route it on INT1 pad.
