For my particular application I have to use the EVAL-ADXRS646Z.
How can I determine postion from simply measuring the output?
There is no need to apologize!
I offered some tips on the interface part of this discussion in the following thread:
How to Usea an EVAL-ADXRS646Z Gyroscope
With respect to calculating angle from the rate of rotation measurement, that is pretty simple: just integration the rate of rotation over time to generate the angle estimate. You cannot do this indefinitely, because the bias error in the rate signal will cause a drift in the angle estimation over time.
Figure 2 of this article offers a conceptual view of how gyroscopes and accelerometers can contribute to pitch and roll angel estimation.
I hope that this helps and look forward to any further questions that you have on this topic.
Hmmmm.... I'm not sure I have ever seen anyone develop position estimates from a gyroscopes measurements. You seem pretty convinced that this is your only option. Can you help me understand why?
We are trying to focus each discussion on one question. Since the original post was about connecting to an Arduino, I branched your second question (about position estimation, using this gyroscope) into a new discussion.
By the way, are you trying to track angle (not position)? We will do our best to help, but aside from a simple integration (running summation, divided by the sample rate), more details on your functional and performance goals might help.
Thank you for your help.
My apologies; yes, I'm trying to track an angle.
I am hoping to use this with a PLC that only works with analog signals.
I mentioned using it with an Arduino for testing since it is something I'm familiar with.
Thank you very much for help.
