Accomodating 2 byte information into one

[Diaspora]

Dear Experts,

Assume, I am sending the value of 2 boolean buttons,

                                   1st boolean value being 0, It would occupy 1 byte

                                   2nd boolean value being 1, It would occupy 1 byte

Hence, I will be sending 2 bytes of information. Kindly someone let me know how I can accommodate the value of both boolean buttons into 1 byte of data. Thank you in advance

Build an array from your two boolean values.

Then convert this boolean array to number, then convert the number to U8:

Wow! Thank you for the solution, dear GerdW. I will try implementing the same.

Using one byte, you can send information of up to 8 booleans, of course.

What is on the receiving end? Do you have control over that? How does the other side expect the information?

Dear GerdW, I am able to implement the same. Thank you.

Dear Experts and GerdW,

I tried implementing the same, but my output is differing a bit. As you can see, your output is displayed as follows

But, my output is displayed as follows.

Kindly let me know why this difference is and how to achieve the output representation as yours. Herewith, I attach my vi here. Thank you in advance.

While I used one TRUE and one FALSE boolean your two booleans are both TRUE…

(Did you take some time to learn about those different display/radix options of numerics? Do you understand how to read numbers formatted and displayed with binary radix?)

On your VI:

Why do you need the local variable? Why do you introduce a race condition?

Why is there no wait function in the loop, so polling for user input as fast as possible?

When I do the same, this is the ouput.

As you can, the radix for binary is chosen.

So you don't think GerdW is an expert? 😋

For the numeric, go into the display settings and change the display format to "%08b".  This will set the minimum length to 8 characters and pad 0s on the the left in a binary format.

For the string, I am not sure what %u will do as that is supposed to be fractional seconds for a timestamp.  Set the format to %08b.

Hi crossrulz,

as an expert I can say %u formats an unsigned integer… 😄

Spoiler

I had to look up the LabVIEW help, too, to learn about this format code.
