There is no requirement that you pair an EQ_PERIODIC with an EQ_TRIGGER. Take for exmaple

|
The atexit() function has been implemented in the current develop branch of midas, see

 06 Dec 2024, Stefan Ritt, Info, New slow control framework "mdev" 
|
A new slow control mini-framework has been developed for MIDAS and been successfully tested in the Mu3e experiment. It
might be suited for other experiments as well.

12 Dec 2024, Stefan Ritt, Suggestion, New alarm sound flag to be tested
|
We had the case in MEG that some alarms were actually just warnings, not very severe. This happens for example if we calibrate our detector
once every other day and modify the hardware which actually triggers the alarm for about an hour or so.

19 Dec 2024, Stefan Ritt, Bug Report, [History plots] "Jump to current time" resets x range to 7d
|
I had put in a check which limits the range to 7d into the past if you press the "play" button, but now I'm not sure why this was needed. I removed it again
and
things seem to be fine. Change is committed to develop.

19 Dec 2024, Stefan Ritt, Suggestion, New alarm count added

Another modification has been done to the alarm system.
We have often cases where an alarm is triggered on some readout noise. Like an analog voltage just over the alarm threshold for a very short period of |

24 Feb 2025, Stefan Ritt, Bug Report, Default write cache size for new equipments breaks compatibility with older equipments

The commit that introduced the write cache size check is https://bitbucket.org/tmidas/midas/commits/3619ecc6ba1d29d74c16aa6571e40920018184c0
Unfortunately K.O. added the write cache size to the equipment list, but there is currently no way to change this programmatically from the user frontend |

I hopefully fixed the waring (narrowing down from size_t to int). Please double check with your compiler.

A new sequencer which understands Python is in the works. There you can use all features from that language.

01 Apr 2025, Stefan Ritt, Suggestion, Sequencer ODBSET feature requests
|
The extended ODBSET[x,y1-y2,z] could make sense to be implemented, since it then will match the alarm system which uses the same syntax.
The $GOODCHANNELS/$BADCHANNELS is however a very strange syntax which I haven't seen in any other computer language. It would take me probably several |
