Darrel, either moving at a constant speed-constant direction or at complete stop, the result of the Integratio won't be the same?

Re: Detecting Horizontal Movement
Hi,
The only problem of that method is small errors ( < 1 LSB measurements for simple explanation ... ) are not taken into account and final result is then false.
Try this into an elevator ( or an automated train ) and I promise you will stay a moment in it calling for help ... !!!

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!

Re: Detecting Horizontal Movement
Hi, Darrel
you sure ??? ...
reminds me a thread about oversampling ... ( about altimeter ) that is a total view of mind for very small variations ( < 1LSB ) - like here !
Have a Happy new year.

Re: Detecting Horizontal Movement
Sure about what?
That "Integration" is a very usefull function used throughout electronics and computing.
Or that I could make a device that detects forward motion using accelerometers/gyros/and magnatometers.
In either case, YES!!!!

Re: Detecting Horizontal Movement
Darrel - Thanks for that very nice example! I completely understand what you are trying to get across now. One last question... will this be sensitive enough to tell if you slooowwwwllllly coast to a stop?
Thank you to all of you who replied to this post! I hope everyone has a safe and happy New Year! Jeff

Re: Detecting Horizontal Movement
Just did a quick look at Sparkfun for accelerometers and found that they have a bunch that look like they could easily be used with PICS. They have a nice comparison here:

Re: Detecting Horizontal Movement
That depends on how slowly you coast, the resolution of the sensor, maximum speed and other factors.
You never really gave us an idea of what you are doing, other than moving over different surfaces, so I can't say.
