two axis inclinometer

[MThem]

Hi..

I am using a CompactRio and are collecting multiple different signals such as encoders, force and pressure transduceres etc.
I recently bought an NI9201 module: https://www.ni.com/en-us/shop/model/ni-9201.html
This module I want to use with my sensor, NTI-230L-LNT two axis inclinometer: http://www.inclinometer.eu/NTI-230L-LNT%2020101229.pdf

In my FPGA i collect the input in a cluster, like I do in all my other modules.

My problem is that in my RT, I want to output a graph, showing the tilt of the sensor in degreese. I also want to output the values, which is the angle.

I have tried Inclination angle = arc sin ((V.out-offset) / Sensitivity), but this gives me just some noise from -0,2 to 0,2 in the Waveform Chart?

If you have any examples or need any thing, let me know 🙂

Hi MThem,

Thank you very much for your post. Your projects sounds very interesting overall, what sort of application are you trying to build?

Reading the article you posted for the NTI-230L-LNT is seems that you are using the appropriate equation to determine the inclination angel. Have you tried using highlight execution and probing to monitor the data flow in your RT VI?

Also it would be really helpful if you could post a screenshot of you VI as well as a screenshot of the data that you are currently getting. I would recommend if you have a spare sensor, to use that and see what results we get in order to narrow down the issue even further. 

I am looking forward hearing from you.

Kind regards,

George

No!  Please do not post a "screenshot of your VI" -- post the VI, itself!  We cannot easily execute or modify a "screenshot", and if it only includes part of the VI, it might not have the "right" part.
