Real time plot (read thru serial).

Dennis,

I tried to do the modifications but I didn't succeed. Can you or Ray please put this on my VI. Thanks

Attach your modified VI.

Replacing one function with another is usually a simple task. Have you tried any of the tutorials?

my bad...  I need better glasses...  Or eye(s)...   😞

I got it. The VI is attached. Now Im trying to do a real time FFT, this is possible??

[Ray.R]

You just needed to create an array as I mentionned in my first post 😉

Circled in red is what you are missing:  Ignore the stuff in the box with a large red X. I had to generate some random numbers.

Can you send me the VI? Because some boxes that you use I'm not finding here. Thanks

[vitor22]

Actually I'm not understanding the first circle in the left, the second element that you connected to the Build Array.

[Dennis_Knutson]

The only thing in the first circle is a shift register (right click on the edge of the loop) and an empty array constant.

You could also use the point by point functions since you are acquiring data that way and skip the whole Express VI/Build Array.

Thank you very much. Now the fft is working.

The other box is probably the build array, which concatenates the input.. 🙂

Glad it's working..  Next task:  cleaning up the block diagram..
