Hi all,

I am writing an areaDetector driver that reads integer time in multiples of fractions of ns. 

ADCore: R3-11

asyn:    R4-22

OS:         ubuntu 20.04LTE

===============

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

  field(DTYP, "asynFloat64")

  field(INP, "@asyn($(PORT),$(ADDR),$(TIMEOUT))TPX3_ELAPSED_TIME")

  field(SCAN, "I/O Intr")

}

In the driver the value is set using (hard coded value here):

setInteger64Param(ADTimePixStartTime,       1661466046253);

However, the PV value does not change from 0.

------------

PV is created:

createParam(ADTimePixStartTimeString,      asynParamInt64,     &ADTimePixStartTime);    

==========

The caput changes the value of PV:

kgofron@myHP$ caput TPX3-TEST:cam1:StartTime_RBV 1661466046253

Old : TPX3-TEST:cam1:StartTime_RBV   0

New : TPX3-TEST:cam1:StartTime_RBV   1.66147e+12

=================

Any suggestions would be much appreciated.
