ASCII into Hex

[Ravinath]

hye. anyone know how to convert ASCII into hexadecimal in labview?

[Tim_S]

Hexadecimal as in an array of numeric values? The String to Byte Array primitive does that.

You need to be A LOT more specific.  I have seen at least 5 different definitions of "hex".  Do you have an example of your data coming in and what you expect out?  Doing this with a VI whose controls and indicators have set default values is by far the best way.

hye. Is the below block diagram is correct? if correct means why i cannot construct it in labview?

How are we supposed to know?  You still have not told us what you expect as an output with a specific input.

 

As far as what is different between the two pieces of code you have there, you need to wire up an I32 constant to the top of the Type Cast, not a string.  It will adapt.

There's a primitive for that.

Adding to @Jimmy Chretien response, if you want the result as a Hex string

Do as ensegre shows or just use a normal string constant and set the display style to "Hex".  Then type in those hex values.  I also highly recommend you set the Visible Items->Display Style to make it more obvious that you are looking at the hex values and not ASCII characters.

hye...when i create a constant for the byte array to string i can't add the hex inputs.how to create it?

[ensegre]

Right click -> Visible Items -> Radix

Left click on d -> Hex
