Memsic 2125 code?

[ScaleRobotics]

I gather from the datasheet http://www.parallax.com/dl/docs/prod/acc/memsickit.pdf the 2125 is just an accelerometer, and will give the pulse output based on the G sensed, but not based on angle. Perhaps you don't need an angle, if you are just wanting to keep the nose of your sub pointed at 0 tilt.


This spreadsheet sort of shows the correlation (or lack thereof) between angle and G sensed. It could be used to make a lookup table to determine angle.

Thanks Walter!
I already have an Automatic Pitch Controller that keeps the sub level and just wished to display the pitch angle as well as the roll angle. Things like "look-up tables" are completely foreign to me and trig math just seemed to complex. Maybe I am just looking at the wrong type of sensor? I saw the electrolyte type and apparently they do not like DC. It also seems silly to buy another Automatic Pitch Controller just to read the roll angle. Best, Ed
