LSM6DSV320X: Confirmation on Free-Fall Interrupt Mapping (INT10)

[Ahilesh_Krishna]

Hello Team,

We are using SensorTile.box Pro with the STEVAL-MKI251A (LSM6DSV320X) adapter board and MEMS Studio version 2.2.0. Flashed the sensor tile box pro with the DataLogExtended.bin firmware which is available in the MEMS Studio

We have logged accelerometer Low-G and High-G data at 1.9 kHz. Additionally, we enabled and monitored interrupts from INT1 to INT10 during the test.

We observed that only INT10 shows an output value of 1, while all other interrupts remain inactive.

Could you please confirm from your side whether INT10 = 1 corresponds to the Free-Fall interrupt for this sensor configuration? Also, kindly let us know if this behavior is expected when using MEMS Studio 2.2.0 with SensorTile.box Pro and the STEVAL-MKI251A.

Thank you for your support.

Best regards,
Ahilesh

Hi @Ahilesh_Krishna ,

Can you do a register dump? it can be obtained with MEMS Studio in the save configuration section.
In addition, what do you mean by INT10?

Hi @Federica Bossi 

Thanks for your reply.

While logging the High g and Low g accelerometer sensor, in the csv file i could see the Interrupts printed from INT1 ro INT10. Only in INT10 i could see the value changing from 0 to 1, Would like to confirm that this is the free fall detection interrupt. Hereby attaching the log for reference.

Hello @Ahilesh_Krishna,

The logical signal Interrupt 9 in MEMS Studio reflects INT1 of the sensor connected in DIL24 socket in your case LSM6DSV320X and Interrupt 10 reflects INT2 of the sensor.
So it depends on your sensor configuration, whether the free fall detection interrupt is routed to INT1 or INT2, both options are possible. You can test in on the Acc Interrupt page.
