ADBase.adl
This is a driver for Gigabit Ethernet and Firewire cameras from Prosilica. It inherits from ADDriver and implements nearly all of the parameters in ADStdDriverParams.h. It also implements a number of parameters that are specific to the Prosilica cameras. The driver is currently only supported under Windows (EPICS win32-x86 architecture) because the vendor library is provided as a Windows DLL. The vendor library provided by Prosilica does callbacks to a user-supplied function each time there is a new frame. Thus, the driver does not need to create a thread itself for callbacks.
The vendor library supports saving individual frames as TIFF files, and this is implemented in the driver. The NDPluginFile plugin can be used to capture or stream images much more rapidly in the netCDF file format.
The driver redefines the choices for 2 of the parameters defined in ADStdDriverParams.h. The ADTriggerMode choices for the Prosilica are:
The Prosilica supports additional hardware timing signals that may be supported in a future release.
The ADFileFormat choices for the Prosilica are:
The Prosilica driver implements the following parameters in addition to those in ADStdDriverParams.h:

The following is the MEDM screen ADBase.adl connected to a Prosilica camera.
The following is the MEDM screen that provides access to the specific parameters for the Prosilica detector.
The following is an IDL epics_ad_display screen displaying the Prosilica detector images.
The driver does not currently support color. This will be added in the near future.
Work is needed on connection management. If the camera is unplugged or powered off which the areaDetector driver is running it does not gracefully recover.
