Jul 24, 2017 00:00

I have seen a related question asked (with no answer.) It seems like the new FFT additions for the 1452 part are either not working or somewhat useless.

I can't seem to get any output when using complex multiplication, as well as getting compilation warnings when trying to use a complex DC value.

And more importantly as was mentioned earlier the complex splitter seems to only have the addition operator, making it sadly useless...

Is this stuff working as intended...?

Updates, additions and improvements to our frequency domain library will become available in the following release tentatively scheduled for Mid September. The only thing I can currently recommend is to try out the most recent Beta version of SigmaStudio.

We apologize for the inconvenience.

Regards

Thank you for the response, and just for clarity, the issues and limitations that I am describing are in the new beta.

I truly hope that you are planning more additions to the frequency domain library than what is in the beta.

Thanks!

MikeSmith12. Could you please share the schematic where you get the compiler error with Complex DC module?

Thanks.
