I got the MLC working on the lsm6dsox. But when i enable stepcount on FIFO my MLC stops working ? these are the 3 lines , is there anyway i can use MLC and stepcount? or will i have to make my own step count tree?

Hi,

I am having the same problem as you hare having. Did you solve it?

What i have done on my side, is loading the UCF file file,

From what i saw the the UCF file is actually overriding some of the gyro/acc output filter and changing the full scale. I have no idea if this is why the embedded functions and other non-mlc functionalities are not working properly.

I have not found clearly any indications in the code that could lead to this kind of limitations.

If anyone have clues why this happen?

Thank you

you need to reset the mlc after writting registers to run off mlc

Hi @MJurk.1​ ,

great you come back to the Community after such a long time!

And glad you shared the solution to the issue.
