Hello,

I have a question for anyone experienced with simple CAMAC systems.
 My understanding is that for a single ADC system you can use a gate to generate a
 LAM signal for triggering on ADC.
 The driver that I have "mcstd_libgpmc_camac" has LAM "not implemented" though,
 so I'm not sure how I should trigger DAQ. The frontend code that I have seems to use a TDC
 as trigger for ADC via "EQ_POLLED" type equipment setting. Should I simply plug in TDC in my
 system and use this as trigger? Is it as simple as TDC generates signal via gate and ADC performs job? 

Sorry if question is super basic, just confused how to trigger without LAM signal.

Thank you :)

I’m beginner of Midas, and trying to develop the slow control front-end with the latest Midas.
I found the scfe.cxx in the “example”, but not enough to refer to write the front-end for my own devices 
because it contains only nulldevice and null bus driver case...
(I could have succeeded to run the HV front-end for ISEG MPod, because there is the device driver...)

Can I get some frontend examples such as simple TCP/IP and/or RS232 devices?
Hopefully, I would like to have examples of frontend and device driver.
(if any device driver which is included in the package is similar, please tell me.)

Thanks a lot.

Dear Stefan,

Thank you for you quick reply.

Yes, I have read the wiki, but not easy to figure out how I treat the individual case.

Okay, I will try to write drivers for my own devices using existing drivers.
(maybe I can find some device drivers which uses TCP/IP, RS232)

Dear Giorgio,

Thank you very much for your kind and quick reply!

I appreciate you giving me such a nice explanation, experience, and great sample codes (This is what I desired!).
They all are useful for me. I will try to write my frontend codes using gift from you.

Thank you again!

Best regards,
Hisataka Yoshida

Dear expert,

I'm going to develop MIDAS DAQ for COMET experiment.
I'm thinking to distribute the load of event building to different PCs.
I attach a schematics of one of the examples of the design.
Please tell me how can I accomplish a kind of "sub-EventBuilder".
I'm reading the midas code to understand the scheme of MIDAS but
it is a lot and I want to know which one to focus on.
Can I do it writing user function based on either "mfe.c" or "mevb.c"?
Frontend program with multithread equipment is the one to do?
Or should I modify the original midas files?


Best regards,
Hiroaki Natori

Dear Mr. Olchanski

Thank you for your comment.
We exect the number of readout channels is ~1000, boards ~100 and the frontend pc <10.	
We expect that trigger rate is a few kHz.

Writing monolithic c++ code may need complete understanding on midas,
and I will consider more about writing from scratch or modifying midas code.

Best regards
Hiroaki Natori

Hi, we are part of the Mu3e research based at University of Bristol. We have a 
remote 32 bit frontend (raspberry pi) connected to a 64 bit Data Acquisition 
system.we are following the instructions at installation/quickstart linux/Build 
32-bit MIDAS libraries. when we execute the commands: 
[mhostpc] cd /home/packages/midas
[mhostpc] make linux32             

we get an error:

Hi again, we now have Midas installed on the Rpi (remote frontend machine) and
have managed to run Fetest on it. Now we are at a stage where we want to send
the Fetest data over to the Data Acquisition machine, which also has Midas
installed. We want this data to be read into the Webserver Status page. We have
tried commands such as: (but Fetest then doesn't run)

./fetest -h DAQ-system-ip-address
./fetest -e sampleexpt -h DAQ-system-Ip-address
./fetest -e sampleexpt -h DAQ-system-Ip-address-with-webserver-port

our experiment name is sampleexpt on Rpi and DAQ machine in their respective
exptab files. Maybe the Rpi is getting confused as to whether it should be
running the experiment on Rpi or the DAQ. We need it to run on the DAQ.

Does the mserver have any role in this?

Thanks you for your kind help (we summer interns are really stuck!)

When we run the following commands on the hostname(DAQ machine) and the remote
frontend(Rpi):
cd $HOME/online
cp $MIDASSYS/examples/experiment/* .
make

We get errors such as
=================
On Rpi:
pi@raspberrypi:~/online/fe_test $ make
...
Missing definition of environment variable 'ROOTSYS' !

=================
On host machine
inking CXX executable frontend
/usr/bin/ld: cannot find -lmfe
/usr/bin/ld: cannot find -lmidas
collect2: error: ld returned 1 exit status
make[2]: *** [frontend] Error 1
make[1]: *** [CMakeFiles/frontend.dir/all] Error 2
make: *** [all] Error 2


The Rpi(32bit) doesn't have root installed but the host machine(64bit) does.
What can we do to fix this?

Thank you this forum has been of great help.

First of all thank you for all the assistance provided so far, especially making
changes to the code in CMakeList file previously for our configuration.I am not
sure whether this is an appropriate Elog for this matter but we are getting the
following error when trying to make rootana, roody and analyzer on our 64 bit
DAQ machine.

At the bottom of this Elog entry I have provided information about the specifics
of our DAQ machine

Below are the 2 errors we are encountering:

Hi,

We've been trying to run Fetest in the attempt of plotting the sine wave data on
the history page on the web server. However each time we've tried running a new
plot we have come across the error of 'no data' from the variables. In the
status page we are clearly obtaining data from the frontend and it is updating
the variable as expected in SLOW.

When setting up MIDAS we managed to produce a history plot from Fetest but are
unable to do so any longer. We did have a go at modifying the Fetest code but
created a backup before doing so and are now running the original backup.

What could be causing the Fetest data not to be showing in the history plot?

Hi, our logger was running. I have tried restarting mlogger (even though we haven't
changed variable names). We ran the following commands one after another and still no
luck with history plot. Is there anything else that could be causing these problems?

Kind regards,

We are new to MIDAS and try to setup a simple system with one ortec camac ADC
AD413A and the hytec1331 controler. Has anyone used this module in MIDAS we
would be grateful for the corresponding frontend.c etc. 

It would be very useful to have somewhere examples of files used by various
experiments in addition to the example files provided in the installation.

Best regards,
Hans 

I'm trying to setup Midas with the Caen vx2740 VME digitizer board.
As the backend driver I used the software from Darkside located here:

https://bitbucket.org/ttriumfdaq/dsproto_vx2740/src/develop/

They implemented some helpers program and one from them should diagnose correct running of digitizer. But when I'm trying to run example program "vx2740_readout_test" I have segmentation fault:

Thread 1 "vx2740_readout_" received signal SIGSEGV, Segmentation fault.
0x00005555555c2ee1 in rpc_register_function (id=id@entry=18000, func=func@entry=0x5555555a2790 <jrpc_helper(int, void**)>) at /home/astrocent/workspace/packages/midas/src/midas.cxx:11947

During the calling this program I have running mhttpd, mlogger and the backend for vx2740 from the repository.

I'm not able to find documentation what is purpose of the RPC? Could someone give any indicators how I can start debug this behavior? Or there is some documentation about the RPC?


I'm freshman in the Midas world, so at this moment everything seems for me very complicated - and I'm learning by doing.

Grzegorz

I tried to update MIDAS installation on Ubuntu 22.04.1 to the latest commit at 
the bitbucket.

I have update the ROOT from source the latest version ROOT 6.31/01.

During the MIDAS compilation I have error:

/usr/bin/ld: *some_path_to_ROOT*/libRIO.so: undefined reference to 
`std::condition_variable::wait(std::unique_lock<std::mutex>&)@GLIBCXX_3.4.30'

The longer version of this error is below.

Has anybody knows some simple solution of this error?

Thanks, GN
