I am looking for an accelerometer that will trigger an interrupt. For example,
I have a sketch that is fairly busy and I cant poll the accelerometer constantly trying to catch an event over XX amount of force. I would like to set a limit (one for each axis ideally) to trigger an interrupt pin.
I could be wrong but ...
It doesn't make sense.
As noted in other threads, accelerometer data requires extensive processing to make any sense of it and a crude threshold function will have little value. All the more so in 3D - if you seriously want a threshold, then you want it to be the same on-axis as off-axis, not 1g on-axis and 1.73g in some other direction.
