RE: nRF9160: LIS2DW12 high current consumption

Maybe I didn't read the sense-edge-mask description enough well and just assumed it should be int because the type is defined as int there.

But I defined " sense-edge-mask = <(1 << 29)>; " in dts and that fixes the problem, thanks a lot!

Hi, the sense-edge-mask property should contain the bitmask of the pins you want to configure with the SENSE event. So the following configuration would set pin 29 to not use GPIOTE IN event:

&gpio0 {
    ....
    sense-edge-mask = <(1 << 29)>;
};

This way you can add several pins to the same field:

    sense-edge-mask = <((1 << 29) | (1 << 30))>;

Or you can use hex values if that's easier for you. This is the mask for pin 29:

    sense-edge-mask = <0x20000000>;

Your workarounds are working in this specific case, but you are "fixing" the wrong part of the if statement.

Best regards,
Stian
