Dante8 support

[MarkRivers]

I am creating this issue to track progress on support for the Dante8.

The master branch only works correctly with the single-channel Dante.

The dante8 branch is where work is being done on support for the Dante8.

The ADC trace is now working correctly on the Dante8 and the Dante1.

This is a screen shot for the Dante8.

The Dante8 only had a real detector input on the first channel, the other channels were disconnected.

The code was simplified by having a single PV that reads the ADC traces. The dante::getTraces() method reads all of the trace arrays and does callbacks on the TraceData waveform records, which are now I/O Intr scanned, rather than periodically scanned.

The DPP parameters are now working with the Dante8. This screen shot shows all of the DPP parameters for all 8 channels.

The Copy1->All button copies the value from Channel1 to all of the other channels. It is implemented in the danteMED.st State Notation Language Program.

The statistics appear to be working for all 8 channels.

The statistics are periodically updated.

I don't understand why channels 2 and 4 have no baseline counts.

[MarkRivers]

The MCA spectra appear to be working. In this case only channe1 has a real detector connected.

I don't understand why channels 2 and 4 do not have any counts at zero energy. UPDATE: this was because they have cables attached. Having a cable attached but not connected to anything greatly increases baseline noise for some reason.

The following still need to be implemented or tested.

• MCA performance seems poor, only updating spectra and elapsed time every 3 seconds or so.
• Implement individual MCA record displays.
• Implement individual ADC Trace displays.
• Mapping mode has not been tested.
• List mode has not been tested,

Most everything is complete and working. All of the items in the previous comment are complete.

The following still need to be done:

• Test the triggering and gating modes in mapping mode.
• MCA mapping mode
  • Has a bug in getAllData that causes a crash when reading 1K or 2K spectra. Have worked around for now.
  • Is not working correctly on the Dante8. Only the first board collects the correct number of spectra, other boards collect too few spectra. This problem is seen also in the SDK test program DPP_Test.cpp. It is probably a firmware problem.
• Documentation needs to be updated with notes for multi-channel mode, new parameters, screen shots.

[MarkRivers]

The Dante8 needs the ability to enable/disable each board. This is needed for detectors with fewer than 8 channels, for disabling bad elements or boards, etc. This has now been implemented.

This screen shot shows boards 3 and 4 have been disabled, all others enabled.

[MarkRivers]

I have merged the dante8 branch into master and deleted the dante8 branch.

I added medm screens to support copying the MCA ROI definitions from board 0 to all boards on Dante8 systems. This is supported for the first 16 ROIs. Each ROI has a screen like this:

The dante8.adl screen has been updated to have the "MCA ROIs" related display widget from which the above screens can be loaded.
