SCDAQ

Rudimentary data taking application for the CMS L1 scouting demonstrator

An RPM is built automatically by the CI pipeline and is stored as artifact of the "build" stage. Important: Once installed, the SCDAQ config file needs to be modified as described in the section below.

The RPM installs a systemd service that can be started with

$ sudo systemctl start runSCdaq

if SCDAQ should be automatically started at boot it can be enabled with

$ sudo systemctl enable runSCdaq

Developing

We try to adhere to the Google C++ style guide.

Code formatting

The C++ code needs to follow the directives set forth in the .clang-format file placed in the repository root. This is enforced by the "check" stage of the CI.

You can format your code either with clang-format -i [modified file], or (in particular for multiple changed files) with git clang-format after you have staged the modified files.

Manual operation

Build manually

Use supplied Makefile to build:

$ cd src
$ make

Run manually

1. Start the run control on scoutdaq:

   $ cd scripts
   $ ./runControl.py

2. Start the data taking application on scoutdaq:
