Hi Shakir,

Are you using LabVIEW Realtime for this? You can just use the shift register to average your values. You can also store your values into an array, use the array size and add array elements function to get the average value. You can also use the mean function under Mathetics -> Probability and Statistics -> Mean under the functions palette.

Good luck!

Hi SHakir,

I was not able to open your program without a broken arror since you were missing a lot of VIs. I did take a look at your array addition. You have not wired the number of iterations to a particular number. The problem with this is that it will keep running until you hit the stop button. This can sometimes result in garabage values being added/calculated. Please refer to my attach vi. I have set up a condition where the while loop will terminate if has done 5 iterations or if the stop button is hit.
