Peak Detect

[Todd_Lesher · Accepted solution]

A filter helps. There's probably a better implementation, but this might be a step forward:

That does look a lot better! What exactly did you do?

And would you mind attaching your VI? It'd be really helpful to take a closer look

[Todd_Lesher]

Ah, I forgot to mention: that image has the code in it. Save it to your PC, then drag it onto a block diagram.

[Cleisthenes]

Do you save it as a .png? I seem to be having some trouble getting it over

[Todd_Lesher]

Right-click on the picture. Select "Save Picture as". It should already be a png.

Then create a new, blank VI and open the block diagram. Drag the png file from the folder onto the BD.

I'd attach the VI, here, too - but somehow the browser won't let me, right now.

hi,

attach your vi wrapped in a .zip file!

Here's my take at a crude signal conditioning. With the relatively clean signal and zero mean the peak counting should be straigtforward.

Wow Todd, that's awesome! I've never seen that before.

Is there any way for the program to process live data, or does it have to be pre-recorded and stored?

[Cleisthenes]

Zwired, what exactly did you do to smooth out the signal?

[Todd_Lesher]

It's called a snippet.

If you replace the for loop with your while loop and use the "Photocell Read" to supply the data instead of the Raw Data indexed values, you'll get calculations as you acquire data.
