Add support for Frame Transfer Mode, Vertical & Horizontal Shift Speed

[mpdunning]

I have a user with an iXon 897 who wants to read out their CCD at the highest possible frame rate. Andor Tech Support told us that we should enable Frame Transfer Mode and set Vertical & Horizontal Shift Speeds to the max. We tried this with Solis on Windows and it works as expected.

So I'd like to add support for these features to ADAndor, but I first wanted to see if anyone else is currently working on this. Or if anyone has any comments, please let me know.

Thanks,

I see now that AndorADCSpeed actually sets the Horizontal Shift Speed of the CCD. So I'd only need to add support for Frame Transfer and Vertical Shift Speed.

I don't know of anyone else working on this.

I'll be happy to accept a pull request. I can test that it works on our older Andor camera.

Thanks Mark. Would you prefer a single pull request for both features, or one for each?

[MarkRivers]

A single pull request is fine.

Possibly of interest: newer iXon Ultra EMCCDs also have an OptAcquire feature that allows you to save presets onto the camera. This includes an out-of-the-factory presetting for 'fastest framerate'. Pages 90-94 of the SDK2 manual include some pseudocode for integrating this.

I could see this being useful for shared cameras, but am not sure how it would fit into the rest of the workflow.

@mpdunning please give a shout if you need a hand with this.

Thanks, that looks like it might be helpful, but how may cameras support this feature? I don't think it would be worthwhile to add to this driver if only one camera supports it.

Closing...see pull request #15.
