Movement detection XYZ Lsm303agr

#1

Hi, can you explain me how enable XYZ Motion detection interrupt INT2? it is for alarm school project.
Thanks

Hi @zzzap,

Here is an example on how to use the interrupt on our SFF board.

If you have any questions let me know!

Thank you for your answer. Your example is for the INT1 pin and only for the Z axis. If I use the INT2 pin is it the same? If I want to detect movement in all XYZ axes (above and below the threshold). Thanks for your help.
PS… the arduino must blink a led when interrupt is generated by motion

Hi @zzzap,

The example shows only one axis indeed.

// If Z goes below threshold the interrupt is triggered
    AccMeter.enableInterrupt1(AccMeter.ZLow, threshold, 0, AccMeter.PositionRecognition);

To enable all axis you can change it to:

AccMeter.enableInterrupt1(AccMeter.XLow | AccMeter.XHigh | AccMeter.YLow | AccMeter.YHigh | 
AccMeter.ZLow | AccMeter.ZHigh, threshold, 0, AccMeter.PositionRecognition);

Best regards,
