Hi All,

I am having a problem using the UInt32Digital type in ASYN. I am writing an areaDetector driver and have a camera that gives status back in 3 registers. I would like to read this value from the camera and put it into a UInt32Digital type so that I can make many records for all the status bits. In the constructor of the class I define:

createParam(FastCCDDCMStatusString,asynParamUInt32Digital,&FastCCDDCMStatus);

Then when I poll the camera I write the parameter using:

setUIntDigitalParam(FastCCDDCMStatus, dcm, 0xFFFF);

This works for all other parameters but not for this one. When the IOC boots, I get the rather cryptic message:

XF:23ID1-ES{Det-CCD}cam1:test devAsynUInt32Digital::initCommon findInterface asynUInt32DigitalType

I am sure this is most likely something stupid, but have drawn a blank to what it is. I would appreciate any help anyone has on getting this going. The code can be viewed at:

Thanks!
