Acceleration Values

[afnan]

Hi

What is the difference between acceleration values used at different places in the program.

` // Now we'll calculate the accleration value into actual g's

Ax = (float)accelCount[0] * 0.000488f; // get actual g value

Ay = (float)accelCount[1] * 0.000488f;

Az = (float)accelCount[2] * 0.000488f;`

VS

lin_Ax = Ax + A31; lin_Ay = Ay + A32; lin_Az = Az - A33;

As the name suggests, the later one is linear but then is the first one angular acceleration?

I am interested in determining G's the sensor board is exposed to.

Thanks

The linear accelerations have the gravity component removed.
