How can I convert a string of hex values to a hex format string programatically?

[chuck72352]

Is there a way to convert a string of the following format:

1400010107070D0305006A01 ........           ("Normal display" string)

programatically to:

1400 0101 0707 0D03 05006A01 ..........      ("Hex display" striing)

I need to do this in order to calculate a CRC16 value.

See attached VIs

Thank you.

Hi chuck,

1) search the forum, this has been asked a lot of times before

or

2) make a loop, get 2 chars from the string, convert to U8 number (by hex string to number),  convert the resulting U8 array to string (by U8 array to string function)

You can iterate over the string and use the String to Hex VI. If you work with two bytes of the string at a time you can get a U8 array of the desired binary values. Then when you are complete you can either work with the byte array of convert it back to a string using Byte Array to String.

EDIT: GerdW typed faster than I did.

My problem is that the orignal string is in hex, but not hex format.

I was much kinder than you since I posted the solution. I was tempted to reply the same as you though. 😄
