From little Endian to big Endian

[JoVMo]

Hi guys, Is there a function in LabView 2010 to go from little endian to big endian? I want to change for example 'B0011000' to '001001B0'.

Hello,

Yes, you do have that, here is the path to access it in the palette (my LabVIEW is 8.6 so the palette might be slightly different to yours) :

You have a "swap byte function", "swap words", "split", "join", etc...

Everything you need 🙂

Hope this helps

Hi TiTOU 

I had the same problem, and your solution is not working for HEX number, do you have another solution, thanks in advance

Using the swap bytes and swap words functions on a U32 will do what the original poster asked.

Are you working with a number (blue wire) or a string (pink wire)?

Hello freinds

i found one sulution for 4 byte (if more/less add/delete replace substring blocks) .... if you have better one please share it ...

how about this

[Alhaidar]

thanks PhillipBrooks

but I'm getting data form sensor as string (Pink wire), more Info see my last replay.

You could do this.

Of course this only works correctly if the string length is even.

Combining a couple of these approaches into one that's a bit more reliable. It works for any length string that contains an integer number of 32-bit values; if you're dealing with 16-bit values, change the representation in the array.  LabVIEW is natively big-endian so this code reverses endianness.

Assuming this is about the 4 byte sensor data only (which is actually a strange way to send in wrong endian order anyhow) I would think this is the most direct conversion. I prefer to convert string numbers into real numbers as soon as possible in a program. Makes things much easier to work with.
