Using waveform to read array in StreamDevice

[=?gb18030?b?yPTAvA==?= via Tech-talk <tech-talk at aps.anl.gov>]

Hello everyone,

    I have a Counter which can store data  to a buffer. 

    (1)  With command "GSDAL?", an array can be read out from the buffer, which looks like this:

      

       fig.1

              

    The first 8 colums are Counter data and the last coloum is Timer data.  Every line end with CR+RF. 

    (2) With another command ¡°GSCRD?00000000100¡±, the buffer can get the following array. Every line end with CR+RF.

      

    fig.2
     

Question 1. How to read the  2-d array (fig 1) into EPICS? Can I use a waveform to do it? Does anybody has an example for it?

   

Question2. I used a waveform to read the second array (in fig.2). 

    record(waveform, "$(D):Array0")

   {

      field(DTYP, "stream")

      field(INP, "@xxx.proto  array_in  $(PORT)")

      field(NELM, "100")

      field(FTVL, "SHORT")

      field(SCAN, "5 second")

   }

in the xxx.proto:

  array_in {

  seperator=CR;  #or CR LF,  no different result

  out  "GSCRD?00000000100";

  in "%5d";

}

    

and the result shows:

 xxx:Array0 200  0  0  0   0  0  ....   0

Surely the data is not read correctly. 

I wonder what the problem is.  

Can I use waveform to read it?

Is there any problem with waveform? For example, the seperator?

If not use waveform, how can I read the array out from device buffer?

Thanks very much for any advice.

Best reguards
