LSM6DSV320X High Accuracy Mode

[yk26_8]

Hi,

I am using LSM6DSV320X for my project. Initially to save power I have Low G accelerometer with 15Hz ODR and 16G with fifo enabled. Once an activity is detected i want to switch on High G as well with 4000 Hz (with High Accuracy mode) and use both high G and Low G accelerometer for data collection. Is this possible if I dont use FSM or ASC and will High Accuracy then work ?. or can this only be achieved with FSM ?

 

I look forward to your reply.

Hi ​@yk26_8 ,

Yes, it can be achieved without FSM.
But it is not possible to keep low-g at 15 Hz low-power and have high-g running simultaneously.
To use high-g, the low-g accelerometer must be moved to High-Performance or High-Accuracy ODR mode first.

Hey ​@Federica Bossi.

So, HAODR is enabled for low-g accel with 15Hz ODR and also the fifo. So, after an interrupt, FIFO can be reconfigured during runtime and also ODR for low-g and High-G accelerometers can also be switched ? And if ODR is switched then new values need to be written into HAODR_CFG (62h) register or ? is this possible ?

The purpose is to achieve least possible current consumption during inactivity.
