Clarification related to LSM6DSOX Working on STEVAL-MKI197V1 eval board

SPANA.1 · ‎2024-09-23

Hi,

I am integrating nrf5340 With STEVAL-MKI197V1 Adapter PCB. We are using I2C interface to communicate. As per the LSM6DSOX datasheet, We need to pullup CS Pin for selecting I2C communication and SDO/SA0 pin status (Either connected to Pull up or Pull down) will determine the LSB Address.

I am observing that, Communication is getting established even though CS pin and SDO/SA0 pin are left open. Another observation is, LSM6DSOX is responding only to address 6b. When we try to communicate using address 6a it doesnot acknowledge.

Can you clarify why we are getting response without CS Pin and SDO/SA0 pin not mounted and why only for address 6b.

Thanks and

Hi @SPANA.1 ,

That sounds strange. Can you share a photo of how are you connecting the adapter?

Thanks!
