Velocity calculation on IIS3DWB #3

Did you happen to derive velocity from the acceleration values? I tried but I am getting very high drift when I do integration over acceleration values.

Very difficult to get accurate velocity using integration of acceleration...error increases linearly. If you need velocity, use the PWM3901 https://www.tindie.com/products/onehorse/pmw3901-optical-flow-sensor//2...
