How to convert 1D array to scalar

[rozoro]

I am using PMD-1208LS to obtain 2 inputs through 2 different channels, using AInScFg.vi

How ever, the values obtained in in 1D array [of numeric(single 32-bit real)].

After applying several equations to the array it still 1D array but [of numeric(double 64-bit real)], now I want to send it to output channel using From Eng.vi --> Aout.vi.

The problem is, that can on happened if my data is in the scalar data type [data of sink is unsigned word (16bit)] not array type?

So how can I convert 1D array to scalar (word)?

Thank you

Index Array??????....

[rozoro]

thank you for the fast replay,

using an index array will let me return only one element of the array ?

what about if i have 1D array, size:1200

is index array will return all the 1200 elements if i left the index undefined?

Oh..  You mentioned 2 inputs from two channels.

Anyway my fault. You can use for loop...You can send one element at a time..and for loop will run for number= Array size

In this case problem solved,

however I thought there was a single block that can do the mission faster instead of using a while loop 😉

Thanks a lot for your effort.

Of course you have other options. The simplest would be to take the mean of the array.

What is happening here is that I am taking 1200 samples per sec from 2 channels which means 600 per each channel in a while loop for 20m sec.

Those 1200 sample are obtained using PMD1208-LS as a 1D array (contains the 1200), so I had to split that array into two array 1D each (600 samples each).

Then I did my calculations and when I am wiring the final output 1D array (size of 600) to the "From Eng" then to "Aout" to give it to my real system using PMD1208-LS.

Its keep telling me wrong wired terminal as their type doesn't match as the type of the source is 1D array of unsigned word 16-bit int. , and the type of the sink is unsigned word 16-bit.

So the problem is how can I extract the elements from the array and feed it to the "from Eng" one by one as if it is continuous.

Any suggestions ?

You can do it the way I suggested or Gaurav's method. Up to you.

I am attaching my labview code. I want to convert 1D array of data into scalar values. I tried using index but the output value was not the same as input. I want to give this scalar value to a meter.

Please help

I have attached a file that converts all the data in an array to scalar. understanding this file would enable you to use the concept in your project.
