Converting Gray Codes to Their Corresponding Standard Binary Numbers in LabVIEW

[Verne_D]

Overview:
This VI converts a binary number in gray code to a standard binary representation.
Description:

Gray-coded binary is used widely with absolute encoders in industry due to the property that each transition involves only a single bit change, ensuring that there are no indeterminate states. For more information on gray codes, see the wikipedia article here: http://en.wikipedia.org/wiki/Gray_code.

Requirements:

• LabVIEW 2012 (or compatible)

Steps to Implement or Execute Code:

1. Run the VI.

Here is Ed Dicken's inverse function to generate the Gray code of a number.

Here is a version suitable for single-cycle execution on an FPGA.

Here is an efficient version of the inverse function.

Thank you for this version. About 25x faster on my machine !

No problem, thanks wikipedia!
