Interpolation on the FPGA

Go to solution


I would like to smooth motion of my linear motor. For example I would like to run a program on the cRIO in scan mode let say 1ms scan interval and then do interpolation between output points (for example from sin wave) on the FPGA scan interval 100us. I wrote little programs but my linear motor does not move at all. I cannot find where I made a mistake or/and something is missing.


Any help will be approciated.


I put in the attachment my FPGA file as well as host file which I run on the cRIO.

Dear Kamil,

Is it possible to see your labVIEW project explorer file?

Kind regards,

Dear Alex,

Thank you for interested in my topic. I have just figured out how to do it. I went through this example: However I modyfied a bit FPGA interpolation method. The one that is described does nove me smooth enough movement. I attached files if somebody will need one day. I think the case is closed.
