Hi Melady, Did you made any progress with your CCD front end interfacing to our cameras ?
I am organizing a workshop at RMLL 2010 in France http://blogs.elphel.com/2010/06/elphel-workshop-in-bordeaux-during-rmll-2010/, would be nice to meet you at the workshop. Also it would be really useful to others if you can describe your project on our wiki. It would also allows us to more easily help you to solve bugs.
