AreaDetector / ADURL queries

["Heesterman, Peter J" <Peter.Heesterman@ukaea.uk>]

Hi,

 

I have been working with AreaDetector and the URL driver.

This is aimed at providing a training module that uses an IP camera.

 

I’ve been working with release R1-9-1 (I believe this is the newest of the 1.x releases), using medm and the EPICS AD Viewer plugin of ImageJ.

I’m working with an Ubuntu /x64 14.04.3 in a VM.

I have GraphicsMagick 1.3.18.

 

However, I think my questions remain pertinent to release R2-5.

 

Questions:

 

1. In start_epics, I suspect that:

 

        medm -x -macro "P=13SIM1:, R=cam1:" simDetector.adl & is meant to be:

 

        medm -x -macro "P=13URL1:, R=cam1:" URLDriver.adl &

 

2. In st.cmd, in the line:

        {URLDriverConfig("$(PORT)", 0, 0)

 

    Is the brace character intended, or is a typo?

 

    I can make it work if the brace is removed.

 

3.  In st.cmd, some lines refer to R=cam1:, whereas some lines refer to R=image1:, is this intended?

     e.g.

        dbLoadRecords("$(ADURL)/db/URLDriver.template","P=$(PREFIX),R=cam1:,PORT=$(PORT),ADDR=0,TIMEOUT=1")

     and

        dbLoadRecords("$(ADCORE)/db/NDStdArrays.template", "P=$(PREFIX),R=image1:,PORT=Image1,ADDR=0,TIMEOUT=1,NDARRAY_PORT=$(PORT),TYPE=Int8,FTVL=UCHAR,NELEMENTS=12582912")

 

     I can make it work if I change R=image1: to R=cam1:

 

4. In auto_settings.req some lines refer to R=cam1:, and some refer to R=image1:, is this intended?

 

    Again, I can make it work if I change R=image1: to R=cam1:

 

5. The issue I haven’t been able to resolve is this (see screen shot):

 

I believe the software is correctly collecting image data frames, and the ImageJ plugin shows green with correct connection.

 

But – I don’t see any picture...

What could I be missing here?

 

I note that the “Colour mode” is Mono, where the camera has colour.

I also tried this with images/sun.jpg, which is definitely a colour picture.

 

I’ve referred to resources like http://cars.uchicago.edu/software/epics/URLDriverDoc.html and http://cars.uchicago.edu/software/epics/areaDetectorViewers.html for information.

 

Many thanks for help received,

 

Peter.
