convert 1D array of byte to boolean

[julesjay]

hi

I would like to convert an array of byte into boolean arry. I've tried many solutions but there 's always something wrong.

I've tired to use a for loop. The problem is :  with indexing I can't wire and without I obtain only the last byte!

Someone can help me or give me some advices.

thanks

The easiest way is to simply compare against zero value using greater than from numeric palette.  See attached picture.

thanks for your answer but it's not exactly what I need.

As you could see in  1.vi , I've an array of 8 boolean (data) I choose to receive only 2 bytes.

And I would like to see each bit of the 2 bytes.

Wire your array 2 to a for loop. Inside the for loop, put a Number to Boolean Array function. Wire the output of that to the edge of the for loop. This will create a 2D array where each row will represent each element in array 2. If you need a 1D array, use the Reshape Array function and specify the dimension size (8 x the size of array 2).

IT WORKS!!

Thanks you for your help.

Just as an additional note, initializing a "short" array of zeroes, then adding it to the input array is NOT the best way to take an array subset! 😉

In general, you would use the "array subset" tool.

(If the subset starts with element 0, you can also use "reshape array" to truncate to two elements as shown in the attached modification (LabVIEW 7.1)).

Hi

How I can convert the boolean array to a byte array to convert it fainally to a string?

Thank yuo

Hi ysma,

like this:

Please describe your desired goal more precisely. What kind of string do you want to receive? Do you need "TFFT" or "1001" or "9" in the end?

Btw. why do you high-jack a very old thread that isn't really related to your topic?

Than you for your reply.

I need send a sting, letters, numbers or both in a communications system, I could convert a string to this system and transmitted s a boolean aray, I coud receive it, my probelm is getting the string back...

Hi ysma,

pleasy describe the string more precisely, which you want to "get back". Provide examples...
