BMI160 How to calculate time using any motion duration?

[odeng250won]

Hi,

I am using any-motion detection for my test.

In your document, int_anym_dur has beed defined consecutive slope data points.

How to calcuate real time duration using int_anym_dur?

Thanks.

Hi,

Thanks for your inquiry.

BMI160 any-motion duration has two bits corresponding to data samples of 1, 2, 3 and 4 respectively. The duration is related to ODR. For example, if BMI160 accel ODR is set to 100Hz which is 10ms interval, then when any-motion duration is set to 1 sample, any-motion interrupt will be generated whenever there is a slope data sample that exceeds the any-motion threshold. When any-motion duration is set to 2 samples, any-motion interrupt will be generated if there are two slope data samples that exceed the any-motion threshold between 10ms.

Thanks.
