Modification for Coincidence Tables

[BenK3nobi]

Hello,

not sure who is still reading here?
There was a new feature added to the hardware, such that it is possible to do coincidence measurements with the coincidence tables. Manual 1.2.4. Somewhere around page 117.

I wanted to implement that here, but it is a little bit more complicated than I thought.
So question, is this feature already implemented to use here? And if not does anyone care to discuss about how to best implement this?

Cheers,
Ben

Hi!
I haven't used this board for quite a long time (4 yrs or even more).
But if someone would implement this feature and share it with everyone, it will be great.

We will most probably implement it since it i needed for some beamtime at the end of the year.
But the first attempt failed, simply because we lack the intuition of the implemented interface.
That's why I am asking, how to properly tweak everything to get this running :-)

I made some dirty hack which appears to set it already in the interna of the SIS, but I have to set some register bits which I do not get properly running.
If someone of you might have time to join me on a zoom/discord/skype talk and discuss a little about the codes interna, that would be awesome.

Took a look at the manual page you mentioned. It's easy enough to read/write from the Trigger Coincidence Lookup table registers, not sure what the Lookup table entry values actually mean though.

It wouldn't be too difficult to do but I don't have the ability to implement and test this feature. Email me and we can maybe set up a brief zoom meeting some time

The lookuptable took me a day to understand.
Using the already implemented function read/write works as you already mentioned.
We will do the implementign and testing, so that's fine Just want to make sure that everything fits together with the rest.
Will send you an Email soon. :)

Small update here:
We got it running using c++ based software and the VME Bus.
As soon as it also runs via the python library I will file a pull request :-)
