LSM9DS1 I2C address identification

Hi,

I am planning to use

LSM9DS1

9DoF sensor in our project.

As per datasheet table #2, Least significant bit for I2C address is [SDO_ A/G or SDO_M ]= SA0.

From this information & Table#19, I will be able to identify I2C address for

Accelerometer and gyroscope.

How can I set address bit 1 of SAD[1]/SA1 to identify

Magnetic sensor

I2C address?

Awaiting for earliest response.

Regards,

Ritesh.

Hello Ritesh,

It seems like a typo in the datasheet Table 2 Pin description: SDO_M Pin #6 should set I2C LSB+1 of the device address (SA1) for the magnetometer while LSB (SA0) is always 0. So you can use this pin for your magnetometer identification. I'll ask for datasheet correction.

Regards,

Petr
