calculating beat per minute

[burcu]

I use Labview 6.0. Icouldn't open this vi.Would you please save it in 6.0 ?
Thanks

Sorry, I can't.
But here is an image of the vi...
Hope this helps !

Dear Charly,
I've tried to do what you said to me. But I couldn't achieve. Would you please have a look at vi attached. I couldn't synchronnize loops. And I really don't know if I did the right thing for other parts of the vi or not .
I need your help.
Thanks

Do not pass the "Actual sample period" between the loops. This blocks the second loop that will wait indefinitely for the first one to stop that's called "dependency".
Instead, create an "Actual sample period" indicator in the first loop, then create a local variable of this indicator, put it in the second loop and wire to the div nodes.

If you want to explore other solutions to the loop synchronization problem, you could have (latter !) a look to the "Queue" function.

Keep wiring !

Hi,

I've created a local variable for actual sampel period and put it in the second loop .
But second loop runs only one time and then first loop runs infinitely 😞

Also while second loop runs once,data comes as #0 to division node so I still can not calculate beat per minute.

I don't have much time left to finish this vi.

What should I do now?

I'm sending the modified vi and a better file record.
I'm waiting for your help.

Best Regards...

Here is the file record.

OK, I found again your posts.

Hi Charlie,

Of course I kept my promise and wrote down your name 🙂

I know that to calculate the absolute
time the formula is


+ *

Sample period=1/sample rate

But I don't know how to implement this to .vi

Would you help me for the one last time,

promise I won't bother you anymore 🙂

[burcu]

In my previous post some characters are missing.I'm wroting again.
The absolute time is

trigger time+sample number*sample period

for my vi sample period is 1/sample rate
sample period=1/440=0,002272

Enclosed I wrote a vi for this formula.But I don't know how to implement this to my vi:(

I wonder that when I create an indicator for date/time string in my virtual instrument vii I can see acquisition time and each time value of 433 samples.However, why can't it save these time values as seen in the front panel.

I appreciate your patience to me 🙂

Regards

Only part of it !

Anyway, the answer has been adressed to your most recent post...
