LSM6DSO: Cant trigger the interrupt pin 1 on fsm event

SBela.1 · ‎2023-01-19

I have tried this example lsm6dso_fsm.c (github stm32 STMems_Standard_C_drivers

) and successfully trigger the int1 pin but found that comment the line 310 the pin does not trigger.

Digging deeper I found that I need to read/poll the EMB_FUNC_STATUS_MAINPAGE (35h) register for the int1 pin to trigger on a fsm event.

Is it a known behavior? Is there a way to bypass that and trigger the int1 pin without reading this register?

Hi @SBela.1 ,

Welcome to ST Community!

You can do this by setting EMB_FUNC_LIR ='0' (reg 17h).

Hope this helps.
