I need to convert a series of numbers and strings into a hex formatted string

[hpitter]

but when I am finished putting all the elements together the format isn't right. For example I get "02310233E14003" instead of "0231 0233 E140 03".

If you need spaces every four characters, the easiest way to do so would be to manually insert them. I.e. convert your string into an array of U8 (there's a function that does this already in LV), feed it into a for loop using auto indexing, and every fourth iteration insert a space into the array. Then convert it back to a string and there is your formatted string.

But there really aren't spaces there its to a hex display format that I need to send to the device. It won't accept a hex string.

What exactly do you need to send to the device? In other words, do you need to convert the numbers and strings into their ASCII values, or are you trying to send values as a binary encoded string?

If you need to flatten things to a string (i.e. make them hexadecimal), you can use the "Flatten to string" VI.

If you need to turn the hexadecimal number into a string, you can use the "Format into string" VI.

Perhaps some more information would be helpful to solve your problem?

I'll try that and see how it works (flatten string.vi). Thanks

Check out this link, which explains how to do it and has sample vi's to try:

You may also want to try (or look at) the function "String to Byte Array" which is located at the: Functions>>Numeric>>Conversions palette.
