Change Byte order of HEX string

[Kenny_K]

Hello,

I am having trouble with changing the byte order of a HEX string, I hope you low level gurus can help me out.

I have a HEX input string 12345678, and I need to change it to 78563412.

I tried using the Byte Swap vi, but it does not do anything.

I am told this is an endian issue, but when I try to convert this to a number, and then back, it does not look right.

HELP!

Seems to me all you need is the Reverse String function.

Well that was easy....good lord.....

I had assumed it would have taken 12345678 into 87654321 so I didnt try it.  But LV must know it is in hex and handle is differently.

Thanks.

Reverse String just reverses the BYTES (2 hex characters), not NIBBLES (1 hex character).  Almost everything comse down to the byte.
