from byte to any number of bit representation of same number generically vi

[estradjm]

Has anyone made a VI that can concatenate bit arrangements of irregular sizes (like 5 bits) together to form a byte array?

I have three 5 bit numbers that I want to put into two bytes in little endian order. Is there a a way to automatically split up the bits to just fit into the array?

What happens to the bit that is not accounted for within the 15 bits?

How do you currently have the 5-bit numbers stored?  U8?  Boolean Array?  String?

U8 representation. Display format is binary, but not sure if that matters.

You can build an array of binary values, then do "Boolean Array to Number."  If you already have 3 5-element arrays, just append them.  The output is a 32-bit value with all the unused bits set to 0, so you can convert that to a U16 which will have your data in the low 15 bits and a 0 in the highest-order bit.

EDIT: Alternatively you can just do some bit math such as shown in this image:

I was trying to come up with something more generic, but it looks like nathand might have the best solution for your particular problem.  His code there will give you a U16.  If you need a btye array, you can use the split number and build array.
