raschemmel:
I think what he is saying is that Gravity causes the acelerometer to register aceleration and the amplitude is a function of the angle.
(I could be wrong too. I am still trying to understand this)
I still don't get it. An accelerometer measures delta in enertial energy in x,y,&z. when the difference in enertia reaches zero (there is no more acceleration in that vector), the output for that vector goes to zero. That measurement is not an indication of how far the chip was moved, but rather, how fast (or hard) it was moved. So how does one (with any level of accuracy) get degrees (as measured by a protractor), especially when acceleration has dropped to zero.
doesn't make any sense to me.
