bit array

[mikeporter]

I am also using V8.2, the 4.x data option doesn't appear until you wire a data type to it that would be effected by it. In terms of the data size, all you have to do is take the code I sent and change it do a conventional flatten to string and you see that the result is much larger (29 bytes). Using what I posted you get 26 bits in 4 bytes (plus a 4 byte bit count) I don't know how you would get more compact than that.

Don't confuse "booleans" and "boolean arrays". We are talking about boolean arrays here where each element occupies only a single bit before LabVIEW 5.0 (check the online help).

You only see the 4.x option if you wire a boolean array.

Hi mikeporter,

Is the bit count always 4 bytes. How do we determine the bit count for an arbitrarly sized bit stream.

Thank you very much for your replys,

Tim

Yes it is always 4 bytes, but you don't have to worry about generating it, the flatten to string function does that. Though, as my code demonstrates, you can extract it to look at if you're curious.
