RE: GPIO event not triggered by accelerometer interrupt

Hello,

Have you tested the pin_change_int example found in:

SDK16\examples\peripheral\pin_change_int

As far as I can say, your setup looks pretty much the same (hitolo instead of toggle, but otherwise, similar.

I don't know what your sensor does. Have you tried shorting the INT_PIN to both GND and VDD? Does anything happen then? Can you confirm that you use pin P0.11?

The reason I want you to try and short to both GND and VDD is that perhaps both your sensor requires another pull configuration. Perhaps you are using pullup, but the sensor only pulls the pin high (and expect a pulldown).

Try to physically short the pin to GND and VDD (a couple of times), and try to change your pull settings.

Best regards,

Edvin
