Hi, I am working on synchronising the timestamp on an IOC with a timestamp register on an FPGA. I need access to the 32 bit fixed point nanoseconds word that makes up the lower half of the EPICS
timestamp. Using the “Soft Timestamp” I can only get the value as a floating point number (using ai) or a string (using stringin).
Is there a way of getting it in the fixed point format I want? As I understand it “Soft Timestamp” only works with ai and stringin records. Ideally I’d like support for longin records as
well. record(ai,"$(SYS)-EVR:EventTimestamp"){ field(DTYP,"Soft Timestamp") field(TSEL,"$(SYS)-EVR:Event-14-SP.TIME") } The record is processed by a forward link from "$(SYS)-EVR:Event-14-SP” Many thanks Will |
