Tap detection with MPU6050

Hello,

I need to implement tap detection with MPU6050. I had a look at the Register Map MPU6050 docs but there aren't any information on tap detection there (only free fall, motion and zero motion) while tap detection is widely advised as a feature of such sensor.

How can I implement that?

Thanks,

Fabio

The MPU6050 does not support tap detection. For implementing, you need to be aware that taps occur at a very high frequency, typically around 400Hz. You should be able to detect high impulse peaks at this frequency.

Wow. Than you have a serious issue in your documentation.

MPU-6000 and MPU-6050 Product Specification Revision 3.1 (and al the previous)
Page 10.

The triple-axis MEMS accelerometer in MPU-60X0 includes a wide range of features:
