Hi How to find the angle made by the accelerometer using arm lpc2138 ? also help me to implement the cordic algorithm to find arctan ?
Thanks in advance
Actually, I guess you could use just one axis provided your system is suitably constrained...
... you could try something like this to see what you get from an accelerometer:
play.google.com/.../details
(I guess there'll be similar stuff for other devices)
Hi The apps works great.. but it was not showing the tilt angle made by the accelerometer. I wanted to find the tilt made by accelerometer. Is there any method for finding that.. ?
Thanks
You missed my point!
The apps demonstrate the outputs that you get from an accelerometer; I suggested that you use this to think about how you could deduce tilt from that information.
Again, it is really just basic trigonometry.
Probably the sinlge biggest market for MEMS accelerometers today is in phones and similar devices precisely for determining how the screen is being tilted so that the display can be adjusted accordingly. So it is a very well-known and well-documented subject - just a little googling should soon get you plenty of information...
