Experimental Physics and

I knew leaving out the proto file was going to bite me!  They’re using %d, so I guess that means they’re going into rval. 

 

getCurrent {

    out "AD 0";

    in "%d";

}

setCurrent {

    out "DA 0,\$1";

}

 

I modified my records to the following:

 

record(ai, "$(P)$(R)GetCurrent") {

    field(DESC, "Read output current")

    field(DTYP, "stream")

    field(INP, "@devPCU50_300.proto getCurrent $(PORT) $(A)")

    field(SCAN, "1 second")

    # field(SCAN, "Passive")

    field(PINI, "YES")

    field(EGU, "Amps")

    field(ESLO, "0.001")

    field(LINR, "SLOPE")

}

 

record(ao, "$(P)$(R)SetCurrent") {

    field(DESC, "Write output current")

    field(DTYP, "stream")

    # field(SCAN, "1 second")

    field(SCAN, "Passive")

    field(OUT, "@devPCU50_300.proto setCurrent(%d) $(PORT) $(A)")

    field(PINI, "YES")

    field(VAL, "0")

    field(FLNK, "$(P)$(R)GetCurrent")

    field(EGU, "Amps")

    field(ESLO, "0.001")

    field(LINR, "SLOPE")

}

 

And that seems to be doing what I want (screenshot attached). 

 

I think the EGUL and EGUF fields and LINEAR for the LINR field might do the same thing, but I haven’t quite parsed the aiRecord docs yet.

 

Thanks!
