Folks, I have released version R1-0 of a new areaDetector driver called NDDriverStdArrays.
This is from the documentation: ************************************************** This is an areaDetector driver that allows any EPICS Channel Access client to create NDArrays in an areaDetector IOC. It is the logical inverse of NDPluginStdArrays, which converts NDArrays in an IOC into standard EPICS waveform records
for use by Channel Access clients. The NDDriverStdArrays driver receives EPICS waveform records from Channel Access clients and converts them to an NDArray in the IOC. The clients must also write to additional EPICS records to define the structure of the NDArray. It is similar
in concept to the pvaDriver which receives EPICS V4 NTNDArrays over the network and converts them to NDArrays in the IOC. pvaDriver only works with EPICS V4 PVAccess clients, while NDDriverStdArrays works with EPICS V3 Channel Access clients. One use-case for this driver may be to receive data from the EPICS sscan record. By putting such data into an areaDetector IOC it could then be saved with the standard file saving plugins. It could also be processed with ROI plugins, and
then visualized with the standard areaDetector viewers like ImageJ. The driver has 2 modes of operation, AppendMode=Disable and AppendMode=Enable. When AppendMode is Disable then each write to the waveform record will generate a complete NDArray. When AppendMode=Enable then the waveform record can contain
just part of the NDArray data, and data can be appended by multiple writes to the waveform record to construct the complete NDArray. ************************************************** This is from the R1-0 release notes: ************************************************** Initial release. This release requires changes to ADCore that were made after R2-5.
They will be present in R2-6, but until R2-6 is released the master branch of ADCore should be used. ************************************************** The home page is here: https://github.com/areaDetector/NDDriverStdArrays The documentation is here: http://cars.uchicago.edu/software/epics/NDDriverStdArraysDoc.html Mark |
