concatenate array elements

[ebuckbuck]

Hello , 

I had a string (HEX format 8A6E) which i converted to a boolean array (0,1) . Now I need to further parse this array of (0's and 1's) like taking MSB and bits 12-15 .....but its all in an array.

So to do that currently I can only think of passing it into array subset (results in smaller arrays as needed   [0,1,0,1] and then concatening elements [0101] . This concatenated value will then be converted into decimal . 

Any help of concatenation of array elemants(numeric) ...or suggestions how to parse such problems better.?

2Darray of hex strings---> nned to convert in binary elements-->extract various bits combinations from each row 

Thanks a lot

You need to be more clear. How exactly did you convert the string to a boolean array? A boolean array has T|F, not 0|1. You don't define what you mean by "decimal". A decimally formatted string? A numeric set to decimal display? Something else?

Why don't you attach a simple VI containing your input strig as a diagram constant and tell us what kind of output you expect from it.

Most likely, all you need to do is unflatten or typecast the string to a U16 numeric. One simple step!

Please find the Vi attached . .Block diagram

I did typecast the ASCII string to U16 ..Then to binary(T\F) and further (0/1 array) . 
Now my hex values are in binary form but 0/1's are elements of an array rather than concatenated value. 

so lets us say i need bits 12-15  and then convert them to decimal , I will subarray the elements(12 -15) and am stuck further in mergring the bits togther to form 4 bit binary value which is to be converted into decimal. 

Thanks

You still have not said what the final output should be (datatype, value, etc.) The term "decimal" is ambiguous.

[altenbach]

Here's how to convert the 4 MSB to a numeric. (for other bits, you might need to add a mask (logical AND with xF, for example)

[ebuckbuck]

final output after bitwise operation will be decimal ..i.e if bits 12-15 are 0111 ....then it should be  7 ....

Meanwhile i figured out that I have two ways to carry out bitwise operation here ....Firstly I manipulate U16 integers through bitwise operattors here(shifts ) ...or use byte array and then index /sub array to extract required bits ....

but still this gets real cumbersome to draw compared to programmatic control of same operations in C,matlab...

I am sorry if I am not clear at all ...or ambiguous ....but I really appreciate your time ..

Thanks

Hi, ebuckbuck,

I know what you need through your code, for the highest bits, here has a simple way to turn it into decimal, I think it is much more difficult for the customized 4 bits.

Best Regards!
