[IMU] Talking to sensors on sensor hub

[BA_]

So i have a LSM6DSOX and connected to its sensor hub LIS3MDL.

Currently I'm trying to log data to feed into the NanoEdge studio.  So i need to grab data from the actual LIS3MDL.

On the sensor hub you can read and write registers through the sensor hub correct?

[BA_]

So you set the address to be a read or write SLV0_ADD (15h)

Then with SLV0_SUBADD (16h) you can set the register

Then this is used to write the value DATAWRITE_SLV0 (21h)

But i don't know how a data read works.  Also not sure how you read more then one sensor?

[BA_]

The read somehow comes from the SENSOR_HUB_1-18

Hi @BA_ ,

On github you can find some official examples on how to implement sensor hub using LSM6DSOX and LIS2MDL. You can use them as starting point.

Hope this helps 🙂

This looks good thanks :).

This looks like it will help a lot
