areadetector / adfastccd

An EPICS areaDetector driver for the LBNL Fast CCD

areaDetector

The top-level repository for the EPICS areaDetector software. This repository contains mostly documentation, configuration files, and a top-level Makefile to build the entire areaDetector package.

The areaDetector code is contained in submodules under this module. Four of these are "core" submodules:

1. ADSupport. This contains the source code for support libraries (TIFF, JPEG, HDF5, XML2, etc.). This is required for Windows and vxWorks, and can optionally be used on Linux and Darwin.
2. ADCore. This contains the base classes, plugins, and documentation.
3. ADSimDetector. This contains an example 2-D simulation detector driver and IOC.
4. ADViewers. This contains viewers for displaying areaDetector images in ImageJ and IDL.

All of the other submodules (ADProsilica, ADPilatus, etc.) contain drivers and EPICS IOC applications for specific detectors.

Additional information:

• Documentation home.
• Installation Guide
• User Guide.
• Release notes and links to source and binary releases.

See the following documentation about the git submodule feature and how it can be used:

• The Git Book
• Git Book tutorial on submodules

To get a clone of the full areaDetector distribution (core, plugins and drivers) do a recursive clone of this repository:

Discuss how to configure "boot" camera from epics IOC

This is a start of a discussion on how to best store the camera config and boot.

FastCCD.cpp fails to compile on Centos 7

FastCCD.cpp fails to compile on Centos 7 because malloc() is not defined. It needs an include of <stdlib.h>.

ADFastCCD lacks a RELEASE.md and a documentation directory

areaDetector repositories should have a RELEASE.md file that describes the changes between each release.

There should also be a documentation directory that describes the driver in some detail, preferably with a screen shot so the controls are obvious.

Add frame rate to base IOC

Image array size doesn't match image1:ArraySize0 * image1:ArraySize1

I'm trying to use ophyd's shaped_image DerivedSignal, but I'm getting this error:

Subscription value callback exception (EpicsSignal(read_pv='ALS:701:image1:ArrayData', name='701_image1_array_data', parent='701_image1', value=array([882, 882, 882, ...,   0,   0,   0], dtype=int16), timestamp=1558385498.360814, auto_monitor=False, string=False, write_pv='ALS:701:image1:ArrayData', limits=False, put_complete=False))

    return np.array(value).reshape(array_shape)
ValueError: cannot reshape array of size 2361600 into shape (2050,960)

I can see that ...image1.shaped_image._shape[0] maps to ...image1:ArraySize1_RBV. These PVs don't match the size of the image (confirmed with caget).

Rather, ...cam1:ArraySizeX_RBV and ...cam1:ArraySizeX_RBV seem to match the shape of the image (2050,1152).

Is this an issue with the configuration of the detector, or the IOC?

Number of images is truncated as 16 bit number

The number of frames is truncated as a 16 bit number and no warning is given to the user. Need a way to get round this or give feedback on error
