Tuning a MMA8452Q Shake Application

Question asked by Tom G on Oct 31, 2016
Latest reply on Nov 1, 2016 by Tom G

Our application requires responding to a transient motion (i.e. shake). There are a number of parameters that can be set: ODR, Full Scale range, HPF, Sample Rate, Transient Threshold, Transient Count. I have implemented all of these and our application is working but the reliability is not optimum. Are there any guidelines to help setting these parameters to improve reliability?


I have been triggering my application whenever the threshold is exceeded at various ODR, HPF, Sample Rate settings. Is this approach sufficient or must there be further processing after the interrupt to improve reliability? What further processing might be required?
