RE: dbpf to waveform

[Hinko Kocevar <Hinko.Kocevar@esss.se>]

Hi Andrew,

I've been looking at the dbpf function in base to see what is going on. I'll see if I can come up with something useful. I'm thinking on handling the DBR_DOUBLE similar to DBR_CHAR, for the start.

I'm hoping that conversion functions in dbPutConvertRoutine array do the heavy lifting of converting char digits to double, once called from dbPutField() -> dbPut(). I think I want to treat source of the data as DBR_STRING, and then rely on putStringDouble() to convert.

Thanks,
Hinko

Hi Hinko,

The ASCII code for ‘*’ is 42, so you can do

    dbpf <record> ‘*’

I admit this isn’t a particularly general solution, but in an emergency...

Our command-line commands were originally designed for the VxWorks shell which doesn’t allow for large numbers of parameters. Improvements welcomed!

&gt; Hi,
&gt; 
&gt; at the moment I can use dbpf to write array of char values (ASCII) to waveform.
&gt; 
&gt; epics&gt; dbpf FEB-030Row:PBI-EVR-030:SoftSeq0-EvtCode-SP dodo
&gt; DBR_UCHAR[5]:       100       0x64                111       0x6f                
&gt; 100       0x64                111       0x6f                
&gt; 0         0x0                 
&gt; OTOH, if I want to write '42', as an integer, to index 0 of waveform I do not get expected results.
&gt;  
&gt; epics&gt; dbpf FEB-030Row:PBI-EVR-030:SoftSeq0-EvtCode-SP 42  
&gt; DBR_UCHAR[3]:       52        0x34                50        0x32                
&gt; 0         0x0                 
&gt; 
&gt; Any way to get 42 into the waveform with current iocsh facilities?
&gt; 
&gt; Thanks,
&gt; Hinko
