Hi Katie,

 

Ø  When I press acquire, the buffer again immediately fills up and neither the values in the "Status" box nor in the stats plugin change.

 

The buffer is not actually “filling up”.  It does indicate that 20 NDArrays have been allocated, totaling 114.3 MB.  Your arrays are 2304x1300 pixels, presumably 2-bytes per pixel, which is  5.71 MB per array.  20 arrays would be 114.3 MB, which is excactly what it says it allocated.

 

When you press Acquire are there any messages on the iocsh console?

 

It looks like the ADAravis driver is allocating NDArrays, but it is never doing callbacks, and never realizing that acquisition is complete.

 

We are going to need to enable some debugging to figure out why.

 

The first thing to do is to enable all asynTrace information from the driver.  In your startup script uncomment this line after aravisConfig():

 

asynSetTraceMask($(PORT), 0, TRACE_ERROR|TRACEIO_DRIVER|TRACE_FLOW)

 

If that does not provide enough information you will need to add some more asynPrint statements in the driver to track down what is going wrong.

 

Mark
