How to print special character like " using sprintf()

RFStuff

Dear All,

I am trying to use getAsciiWave() in SKIL script. I want to vary the Y-column value.

So, I tried as below:-

ITR4=1

getAsciiWave(sprintf( nil "\"/mxp/ESD/INL_PI_64_CODE_MC.csv\" 1 %d ?xskip 0 ?yskip 0 ?formatFloat nil ?xName \"CODE#\" ?xUnits \"[]\" ?yName \"DELAY\" ?yUnits \"fs\"", ITR4)  )

The problem in above is the special character ". I tried using \ before it. This way sprintf works but it gives \" instead of ".

How this can be overcome ?

Kind Regards,

Parents

    I'm not sure why you're doing all this messing around with sprintf. The filename isn't changing, and the other arguments can just be passed as variables. So doing

    getAsciiWave("/mxp/ESD/INL_PI_64_CODE_MC.csv" 1 ITR4 ?xskip 0 ?yskip 0 ?formatFloat nil ?xName "CODE#" ?xUnits "[]" ?yName "DELAY" ?yUnits "fs")

    would do the job. Your approach is building a file name with spaces and ?xskip and ?yskip (and quotation marks) built into the string, which is definitely not what you want to do!

    Thanks a lot Andrew.

    Assigning the filename or any other parameter to a variable does work fine.

    Also one more query:-

    Can we plot using getAsciiWave() for a file of below type:-->

    tx, 2

    rx, 5

    cdr, 6

    The first column is the Xaxis and the second column is the Yaxis.

    No. It only supports numerical column data.

    It wouldn't be too hard to write some SKILL to read the file and produce the waveform data though (I don't have anything to hand that does this though).

    Can we use CCSCreateWaveCSV().

    Not unless you rewrite it. It assumes that both columns are numerical.
