Accelerometer reading

[joseph Degorio]

Hi everyone,
I know this may very easy to some, but can you advice me how to interpret the following values bellow received from USART in order for me to turn a motor clockwise or counter clockwise.

x -17 y 40 z -39
x -17 y 38 z -35
x -17 y 39 z -36
x -15 y 41 z -34
x -14 y 41 z -34
x -14 y 43 z -34
x -14 y 42 z -33
x -13 y 42 z -34
x -12 y 42 z -34
x -13 y 43 z -35

These values came from a mobile phone with accelerometer sensor.

Thanks in advance,
joe

It might help to know what the readings are with the phone vertical, about 45 degrees to the right, 90 degrees to the right, and the same for the left. I don't quite understand what you are trying to do. Are you trying to make an application that reads the tilt of your phone?

I wrote some code for tilt sensing, but my accelerometer only gave me positive values (from analog ports). Its a little complex figuring out actual degrees. Might be easier to figure out just which way you are turning it.
