I know this has been asked many times.
I am integrating acceleration data from MEMS accelerometer to get velocity.

I found an app note by freescale -

It ignores the sampling time to calculate the area.
The formula should be sample: Vx= V(x-1)+[N-(N-1) * T]. Right?
But the app note it is -
Vx = V(x-1)+N+[((N-(N-1))/2]

V(x-1) is the previous integration result.

... you still have to multiply by time somewhere.

... nonsense: did you misplace a parenthesis?
