I just noticed that you created the parameter with Type asynInt64 but your record has DTYP asynFloat64. That is not correct, and should have produced an error message after iocInit.

You should either use an ai record with DTYP asynInt64 or an int64In record.

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.
