* Prefer to use floating point calculations for centroiding and servo
** EBS to find out if this means we must use Xenomai user-space real-time and hence tolerate context switches

* Frame acquisition and data processing should be a real-time task in *all* modes
** Not necessarily for FLC, depends on availability of RT camera data driver

** Same process as frame acquisition/data processing

! Technical Meeting #8: Software conceptual design

This meeting took place on Tuesday 15 June 2010. Attendees: JSY, DFB, EBS, MF, ADR

!!Conclusions
* GUI should be separate process
** Allows display on console for best performance
** Can be started and stopped at user's convenience

* Frame acquisition and data processing should be a real-time task in *all* modes
** Not necessarily for FLC, depends on availability of RT camera data driver

* Thermal control
** Scope of this software includes thermal control of camera enclosure
** Thermal control should be active continuously, day and night
*** Does this include Peltier?
** Separate process for thermal control (possibly with its own interface to the ISS) desireable, but requires dedicated I/O hardware

* ISS Interface
** Most commands (including mode switches) can be synchronous - avoids extra threads/callbacks
*** Exception would be any commands to move actuators

* May need to account for future off-axis offsets when choosing initial position of subframe on FTT Mode start
** Prefer not to have ISS perform calculation

* Prefer to use floating point calculations for centroiding and servo
** EBS to find out if this means we must use Xenomai user-space real-time and hence tolerate context switches

!!New Tasks

!!!Medium Priority
* EBS: Design real-time task in more detail
* JSY: Investigate use of multiple threads in ISS framework
* JSY: Ask Allen if systems are allowed to run indefinitely
