hex data to integer

Share icon

Hi,

I do have a sensor which sends out lines of hexadecimal data what look like this:

0006 0006 0004 0002 0000 0001 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0013 0DB0 04E0
0012 0004 0000 0001 0001 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0018 0D88 04E0
0011 0003 0002 0000 0000 0001 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0017 0DB2 04E0

I would like to convert those to integer numbers. But I do not find a hint how to do that. Any help?

Thanks!

If you look at the help for LoadWave, you can specify the column format to be a hexadecimal number:

LoadWave /B="F=10;" ... DisplayHelpTopic("LoadWave")

Hope this gives you an idea.

Hi KurtB,

Thanks for your fast answer. Well, sorry, I did not describe the dataset well enough:

it is an ascii file wich contains the hex numbers above.

I would like to read this ascii file and transform the 19 hex number waves to decimal.

The following appears (in my quite testing) to load the data into a matrix wave:

LoadWave/J/F={19,5,0}/B="C=1,F=10,W=4;C=19,F=10,W=5;"/M myFileName

This may well not be applying all the flags properly - I just played around until I got something that appears to work.

You then just need to convert that to a 1D wave, or do whatever you need thereafter.

Good luck!

Kurt

EDIT:

There is probably a matrix op that does this better, but the following converts it to a 1D wave...

Wave wTemp = wave0 // replace wave0 with your own loaded wave name
MatrixTranspose wTemp
ReDimension/N=(DimSize(wTemp,0) * DimSize(wTemp,1)) wTemp
