Dear experts,
while trying to readout a MIDAS file from a python script. I get the error below at the very first event. Any hint?

29 Jun 2021, Lukas Gerritzen, Bug Report, modbcheckbox behaves erroneous with UINT32 variables

For boolean and INT32 variables, modbcheckbox works as expected. You click, it
sets the variable to true or 1, the checkbox stays checked until you click again
and it's being set back to 0.

Hi all,
for my experiment we ended up with the need of changing lot of parameters (~9000 values) in the ODB at once by the sequencer.
The very first solution was to use a sequencer function with a ton of ODBSET calls, however a more elegant solution may be to provide an "ODBLoad" command |

My idea was to collect some feedback instead of blindly submitting code for a pull request.
Currently I'm just calling db_load() with a given file, so it is only supporting .odb formatting.

As reported by Stefan, in MEG II we have very similar ethernet throughputs.
In total, we have 34 crates each with 32 DRS4 digitiser chips and a single 1 Gbps readout link through a Xilinx Zynq SoC.
The data arrives in push mode without any external intervention, the only throttling being an optional prescaling on the trigger rate.

It seems that a modbselect triggers a "change" in an ODB which has a hot link. This happens onload (or whenever the custom page is reloaded) and otherwise
it behaves as expected, i.e. no change unless the modbselect is actually changed. Is this the intended behaviour? can this be modified? |
