I would like to experiment with writing a driver that snoops incoming fits data from a CCD and that has a BLOB property which in itself stores fits data that a client should be able to display.
While I found the tutorial_three, I did not find it too instructive for my purposes and I did not find any other examples. Could anyone give me any pointers?
You could look into the astrometry driver maybe. Although I don't remember if the driver is snooping the FITS frame or if the client re-send it after retrieving it from the CCD.
Thanks! This should get me started for the snooping part at least.
Possibly I also had a wrong idea of how a client would handle the BLOB property. Does a FITS frame need to be explicitly sent to a client or does it get notified when a corresponding BLOB property changes?
