Changed lines 28-29 from:
JSY is writing up conclusions.
to:
The upper diagram shows the FLC software tasks and dataflows as presented at the CoDR. The lower diagram includes changes discussed at this meeting.
Added line 34:
Changed lines 36-37 from:
** ISS Data Collector probably not suitable as LocalDataCollector and unlikely to be ready in time
to:
** Cambridge-supplied LocalDataCollector
** ISS Data Collector probably not suitable as LocalDataCollector (e.g. issues with retrieval of recorded data), and unlikely to be ready in time
Changed lines 39-44 from:
** Will not be present in standalone role
* TempController has interface to ISS
** Allows ISS to query state
* TempController could control power on/off of camera ("?" on diagram)
to:
** Will not be present in standalone role (neither will ISS Executive/Supervisor)
* TempController (EnvController?) has interface to ISS
** Allows ISS to query state for this process
* Division of tasks between main process and TempController depends on I/O device sharing issues - to be investigated
** TempController could control power on/off for camera ("?" on diagram)
Changed lines 47-48 from:
* Matlab Data Analysis GUI not shown
to:
* Main FLC process will have built-in image display capability using X11 libraries
* We will write a Data Analysis GUI in Matlab (not shown)
Changed lines 50-54 from:
to:
** GraphicalInterface will still include commonly-used diagnostic displays
* Expect to use dlmsg protocols for publishing to LocalDataCollector, with recording to DL-style FITS files
** Facilitates collection of metrology data from DL metrology subsystem
** Can use DL workstation software as interim LocalDataCollector
Changed lines 57-58 from:
* EBS: Investigate ADC/DAC/digital I/O interface cards
** NB environmental control performed by dedicated process
to:
* EBS: Investigate ADC/DAC/digital I/O interface cards and device sharing issues

!!!Changes from CoDR
* GraphicalInterface and LocalDataCollector grouped into single process
** ISS Data Collector probably not suitable as LocalDataCollector and unlikely to be ready in time
* ISS Data Collector shown
** Will not be present in standalone role
* TempController has interface to ISS
** Allows ISS to query state
* TempController could control power on/off of camera ("?" on diagram)
!!!Notes
* Matlab Data Analysis GUI not shown
** Reads files recorded by LocalDataCollector

Added lines 7-22:
* Software requirements for our testing
** Image display for setup purposes
** Temperature logging
** Centroid logging
** Anything else?
* Open Design Issues
** Choose ISS interface flavour: "C" (threads/processes)/"C-no-threads" (event loop)
** Can we use floating point in Xenomai kernel-space real-time?
** How to transmit dark/flatfield frames to/from ISS?
** How to receive off-axis/dispersion offsets from UTCS via ISS?
*** May need to account for future off-axis offsets when choosing initial position of subframe on FTT Mode start
** Choose GUI toolkit
* Plan for camera loan
Added lines 26-28:
* Select ADC, DAC interface cards
** NB thermal control performed by separate process
