continuous averaging for a certain amount of time

[ethen99]

Hi

In my program I have to use a start button to continuously average a value for a certain amount of time(lets say 3s) and keep and show the average the value. The state of the start button should return to off mode after that 3 sec so if the user hit the start button again it reset the array and calculate the average again.

Would you please help me with this program. I have attached pic of what I ahev done

With this vi I can take data after hitting start for 3 sec but I have these problems:

1- I don't know how to calculate average value when finish getting data after 3 sec

2- I would like the start button back to off mode after 3 sec so if I click on the start button again it reset the array and calculate the average again.

Would u plz help me with this vi?

Use mean function to average an array. And wire your time has elapsed boolean to a case structure and reinitialise your boolean control to default in the true case.

Create invoke node as below, just in case you dont know.

Hi aCe, many thanks for your reply. I have tried your methods but I still have few problem. The problem I have now is when I click on the boolean control I can store data in a data array and I calculate the average also when the time has elapsed  reinitialise  method can change the boolean to defualt value

but the problem I have now is what should I do if I want to do the measurement for a specific period of time again. Whit this design I can take the average just one time because and if I want to do it again I need to stop and run the program again. while I would like to take measuremant and take average everytime I hit the boolean control.

I need to also mention the automatic reset is not checked in this vi. Would u plz help me how can I change this vi to the continious averaging for me?

I have attached that part of my vi to this post

Hi en99

I may have misunderstood what you are asking but it sounds like you want your current code to run continuously until you stop it, am I correct?

If that's the case then you could just put a while loop around all your current code, with a stop button linked to the conditional terminal.

Please correct me if I've completely misunderstood your problem.
