WIP: blind attempt to get daig6 useable as a monitor device #35

The read and configuration attrs may need to be adjusted and this may not have enough plugins configured.

@tacaswell this looks good. I thing we can merge, but is it possible to choose one of the two options so I don't break something for someone else until things are fully tested

diag6 = NoStatsCam('XF:23ID1-BI{Diag:6-Cam:1}', name='diag6')
#diag6 = MonitorStatsCam('XF:23ID1-BI{Diag:6-Cam:1}', name='diag6')
diag6 = NoStatsCam('XF:23ID1-BI{Diag:6-Cam:1}', name='diag6')
diag6_v2 = MonitorStatsCam('XF:23ID1-BI{Diag:6-Cam:1}', name='diag6_v2')

I can of course do this once we merge and git pull if it is easier. Just let me know what your preference is.

tacaswell commented 4 years ago

That is probably easier (at least for me!)

ambarb commented 4 years ago

everything seems to work. I just need the beam to come back for final testing.

Also, I did not ask for this part, but I do see that if I change the number of images to be something other than 1 (diag6.cam.num_exposures) this does't seem to work. Onto the next point after a single trigger. Unsure if this is a consequence of the AD for the proslica GT1920. @johnsinsheimer do you know?

johnsinsheimer commented 4 years ago

I'm not sure how num_exposures works with triggering and would have to test. You can look at

ADNumExposuresCounter asynInt32 r/o Counter that increments by 1 each time an exposure is acquired for the current image. Driver resets to 0 when acquisition is started. NUM_EXPOSURES_COUNTER $(P)$(R)NumExposuresCounter_RBV longin

To see if it counts up when you try more than 1.

XF:23ID1-BI{Diag:6-Cam:1}cam1:NumExposures is the PV. If I change the PV by hand, bluesky is not aware, and moves on to the next point in mid-collection.

Reason wondered about this is because I realized there is no "switch" to disable the sclr being triggered by the TTL pulse of the FCCD. WIll speak to chanaka about the soft-glu and maybe we can fix it there. I am not sure this other approach (with number of images) would even work.

Another option is 2 soft-glue, one just to provide some method of having an acurrate clock for 0.3ms exposures in free-run.
