Hi folks,
Is there a way to force compress to take only NORD elements from its INP waveform? I have a big waveform that only has some of its data initialized (a fixed amount per "run"), and I want to accumulate this initialized data in a circular buffer. Has anyone made something similar work? Do I need to interpose an acalcout between the two (which I tried but didn't seem to work)?
Please see example below.
Thanks!
Bruno
$ cat test.db
record(waveform, "WVF") {
field(FTVL, "DOUBLE")
field(NELM, "50")
}
record(compress, "CMP") {
field(ALG, "Circular Buffer")
field(INP, "WVF CP")
field(NSAM, "100")
}
$ softIoc -d test.db
...
