====== DAQ ======

===== How to run =====

  - Connect to the DAQ computer (you must use the LNGS cable network or the [[https://wiki.sites.lngs.infn.it/doku.php?id=vpn:start|LNGS VPN]]:\\ ''ssh my_user_name@172.17.4.212''
  - Load the DAQ software:\\ ''$ source /software/LoadGAGG-DAQ.sh''
  - Prepare a TOML config file following the examples in the ''/software/config'' folder
  - Run with:\\ ''$ /software/GAGG-DAQ-build/bin/GAGG-DAQ /software/config/my_config_file.toml''
  - To make a loop of subsequent runs, open a ''screen'' session and run something like: ''for( ( i=0;i<1000;i++)); do /software/GAGG-DAQ-build/bin/GAGG-DAQ /software/config-files/Thermal.toml; done''

===== How to install the CAEN libraries =====

  - Create an account on the [[https://www.caen.it/ | CAEN website]]
  - Download the USB driver for linux for the V3718 bridge and install it as a system-wide installation. Notice: the driver talks to the linux kernel, so **you will probably have to recompile it after an OS update**.
  - Download and install the CAENVMElib library (in C)
  - Download and install the V65xxController library
  - Download and install the GECO2020 software (for now we're using this to control the HV)
  - Download and install the CAENComm library
  - Download and install the CAENDigitizer library
===== How to obtain and install the DAQ software =====

  - Send your github.com username to Giovanni (create one if you don't), then accept the invitation you will get via email.
  - Clone the repository in a directory of your choice:\\ ''$ git@github.com:GSSI-BolometerGroup/GAGG-DAQ.git''
  - Install the following prerequisites and make sure they're correctly loaded: CAENVME library, CAENComm library, CAENDigitizer library, ROOT.
  - Create and enter a new folder for building the software:\\ ''$ cd /path_to/\\
$ mkdir GAGG-DAQ-build \\
$ cd GAGG-DAQ-build''
  - Compile with cmake:\\ ''$ cmake /path_to/GAGG-DAQ\\
$ make''
  - You will find the executable under ''/path_to/GAGG-DAQ-build/bin/GAGG-DAQ''
