Here is the data sheet
http://www.analog.com/media/en/technical-documentation/data-sheets/ADXL345.pdf
So here is my problem. No where can i find in the data sheet on how to interpret the data
Im not having any trouble communicating with the device and I'm able to read the x,y,z registers
But i have no idea what the numbers mean.
UNLESS I MISSED IT
which is totally possible but i have not found anything in the data sheet that says
ok if you get this two complement number it = this degree of tilt
I do understand there are different degrees of resolution.
For my application i need the highest resolution with the lowest G requirements
I don't even see in the data sheet what the axis limits of tilt are.
Does it reset when you past 90 degree?
For example if its laying flat on a table should i see a value of zero?
Normally to figure this out i would look at that maximum number allowed in the register and divide it by something to know what the resolution is.
However i don't know what that "something" is by this data sheet?
Anyone have any experience with this device?
Thanks in advance
