Folks,

R2-3 of the areaDetector ADPointGrey module is now available.

This is from the release notes:

- Fixed problem determining the maximum allowed packet size when calling SetFormat7Configuration. This could lead to invalid packet size being passed, and could result in an error message each time the PixelFormat or other Format7 parameters were changed.

- Added support for conversion from Raw12 to Raw16. This is needed because the Point Grey library does not support conversion from Raw12 to Mono16. We want to run cameras in Raw12 mode because it is faster than Mono12 or Mono16 and we need to convert to a 16-bit format before sending arrays to plugins.

- Changed the logic when changing property values. Previously when changing the integer or absolute value of a property the property On/Off setting was changed to On, and Automatic mode was always turned Off. This was often not the desired behavior, since if a property was turned off (e.g. FrameRate) then it would be automatically turned back on if the AcquirePeriod or FrameRate PV was processed. Now the Automatic and On/Off settings are not changed when the value of a property is modified. If the Automatic setting is On, or if the On/Off setting is Off then the property value will not be modified.

- Changed the driver to return success rather than an error if a call is made to change an unsupported property. This eliminates error messages for unsupported properties during iocInit.

- Set the record PHAS field on some records to 1, 2, or 3 to control the order in which they process at iocInit. Some records must process before others when changing PixelMode, etc.

- Set AcquirePeriod to have PINI=NO and info(asynREABACK, "1"). This makes AcquirePeriod slaved to FrameRate, which is the preferred parameter on PointGrey cameras.

- Made the OnOff and AutoMode records for all Point Grey properties have PINI=YES.

- Changed pointGrey.substitutions in the iocPointGrey directory to set PINI=YES or PINI_ABS=YES for most properties, even if they are not supported. The driver now silently ignores unsupported properties, and it is a better example to use for cameras where those properties are supported.

- Added epicsThreadSleep and dbpf commands to st.cmd after iocInit. These allow time for enum and soft limit callbacks to occur, and force some records to process again after PixelFormat and other mode records process. The IOC should now start up with no error messages, and with the actual camera state reflecting the current value of all output records.

- Removed the PGHeartBeat parameters from the class definition, they were not being used.
