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

Added lines 29-46:

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 28-29:

JSY is writing up conclusions.

Changed lines 32-33 from:
  • Select ADC, DAC interface cards
    • NB thermal control performed by dedicated process
to:
  • EBS: Investigate ADC/DAC/digital I/O interface cards
    • NB environmental control performed by dedicated process
  • EBS: Investigate whether floating point is allowed in Xenomai real-time code
  • MF: Try reading example FITS image time-series into Matlab

October 22, 2010, at 12:27 PM by 131.111.48.85 -
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
