Hi Neil Lan,

you can use the TypeCast function.

Hi Mike

I saw the result is "8500 0000" instead of the result "85", do you have any comment.?thanks

You probably have a 32bit number wired to the type cast type input. Use a U8 constant (will only work if the sum is <= 255).

This'll work, too.  I'm afraid of casting types...

You shouldn't be. After all, it uses less code, and requires less hoops to jump through.

thanks, I get it

Hi Jm,

it will not work, because the string in my example is as required in hex display.

I think the confusion may lie in the fact that the OP said "Hex display" as well as "Hex format". Those who have used LabVIEW for a long time know these are 2 different things. However, those who have not used LabVIEW for a long time may take these to mean the same thing, and may interpret it one way, as opposed to the other. That is not incorrect, it's simply not making a distinction that they may not be aware of.
