Hi,
I am using the setup with LSM6DSL + LIS2MDL. All works fine, with the exception that once started the conversion to FIFO with sensor fusion, at 104 sps, I observe significant periodical (around 22 samples cycles) noise on the last acceleration axis (Z). With LIS2MDL stopped there is no noise. More, if I disable the internal pull-up resistors, the noise disappears as well.
Any advice on this?
Many thanks,
Florin

Good to hear.
Indeed, the datasheet is not very clear.
You can also refer to application note AN5040 which goes more into details.

First can you share your schematic?

The schematic looks ok, but I have a few more questions:

Hi Miroslav,
Thank you for your time, and valuable questions!
The answers are as follows:
"START_CONFIG
Sensor Hub trigger signal selection. Default value: 0
(0: Sensor hub signal is the XL/Gyro data-ready;
1: Sensor hub signal external from INT2 pad.)"
After configuring it as per your suggestion (OK, done at the right time in the initialization sequence of the assembly), all works like a charm!
Thank you!

Thank you Miroslav, indeed, the Application note is more clear, but all is easy after sorting it out :beaming_face_with_smiling_eyes:.
