Convert hex number to mac address with colons

[sebulban]

This might be a simple thing to do but I can't make it happen 😞

So I need to make a mac address with colons. At first, the Address is  divided in two sections.

First the constant part C87248 and the second part as a running number from 0 to appr. 16000000

The outcome should look like this C8:72:48:00:00:00

The .vi is going to be used in teststand 3.5.

The running number is an input parameter and .vi should return the mac address as a string so that teststand could read it.

These hex conversions in labview drives me crazy. I'm able to convert the address to format

C872 4800 0000 but I can't reformat it the way i want it.

Hi sebulban,

  Please tell me whether the Hex address is a string or an integer...How it is stored in testStand variables?

Thanks and regards,

This should do it, although it's probably not the most efficient way.

Thanks ! That works just fine 🙂

And here is yet another solution.

Note: Right click on the Search And Replace function and check Regular Expression.

Edit: Added the 6 constant to length input of number to hex

Speed is probably not important for something like this. But out of curiosity I did a comparison of all three techniques above. I ran the algorithms 10M times each.
