I need to convert the string representation of 10, 11...15 to A, B...F?

Hi,

I have a channel list that will be in the representation like the following "0, 1, 2, ... 14, 15" in string format.  Of course i won't always be using all the channels so sometimes it might be "2, 5, 15" or "15" or "".  It all depends on the channels that I need to use.  Anyways, using TestStand I need to run a for loop for that runs through the channels and finds the matching string in the channel list then run some more code....Like so:

ChnlList = "1, 2, 3, 11, 15"

For(Chnl = 0, Chnl <=15, Chnl ++)

     {

       If(Chnl is in ChnlList)

          { Then execute this code}

     }

I hope that makes since.  I've tried to take the ChnlList string and converting it to decimals that i could use but can't seem to get it into the right format.

My orginal plan was to convert Chnl to a string and search for that string in the ChnlList in TestStand, but that wouldn't work becasue if Chnl = 1 and ChnlList = 15 then it would execute.

So i moved onto Labview to try and do some converting of that string but I'm struggling to get it into something I could use.  Any of you smart guys have any ideas?

Thanks,

also i'm using LV 8.2, TS 3.5

How about using the 'Decimal String to Number' vi followed by the 'Number to Hexadecimal String' vi?

Easiest would be to use "spreadsheet string to array" (with a comma as delimiter and a 1D integer array as type). Now you can just autoindex the resulting integer array into a FOR loop to process the channels.

Here's a quick draft (LabVIEW 8.2).

It is not very reasonable to carry the channel list around as strings. Once they are integers, the formatting (decimal, hex, etc.) is just a cosmetic issue of the indicator and irrelevant for the code.

Thanks for the help guys, but both of these outputs strings. In order for me to have some sort of number to compare with my loop in TestStand I need something that will convert it to a real decimal number or a real hex number.

No. The blue array going into the FOR loop in my example are the numbers you want. Look at it again! 🙂

Yeah i figured that out pretty much right after I sent the post..opps
