Memsic 2125 code?

To make it easier, you could use a lookup table. Here is an example of one for the memsic for a basic stamp. http://www.parallax.com/Portals/0/Do...3/col/nv92.pdf .The table lookups only calculate on one axis, so they will not be as accurate as a 3 axis solution, but might be perfectly fine for your application.

Thanks!
I guess where my confusion is that SubTech makes an automatic pitch controller (APC-3 and APC-4) that drives a servo to correct the pitch angle with the rear planes. You use the bow planes to change the pitch for up and down. Since the output is basically PWM and with pulsin you are measuring the pulse width then the code is very simple. Trueangle=((10*pulsewidth)+1500)/10. An up angle would be Displayangle = (TrueAngle -900)*2 while a down angle would be Displayangle = (900- Trueangle)*2. So it looks as if you could use a simple calculation to obtain the angle?
