How to reverse an order of an 8 bit value

[esaravanan85]

Hi Altenbech,

Can u explain how to create the LUT..

[RavensFan]

What you can do is create a For Loop that runs N=256 times.  Use the "i" terminal through the code that JB posted.  Create an array indicator out of an autoindexing tunnel.  Now you have an array of reversed bits from i=0 to 255.

Now change that indicator to a constant and copy and paste it into your real code.

Just make a simple FOR loop as follows (or use Yamaeda's code ;)), run the VI so the indicator contains data, and right-click the indicator to create a constant of it.

Use constant where needed. 😄

 

(Note that in newer LabVIEW versions you can use the output configuration of "boolean array to number" as U8, eliminating the "to U8" at the end.)

Thanks for the LUT tip.

For those looking to reverse all bits (regardless of byte size):

Reverse Bits.vim (attached) accepts any numeric type:
