CMS Timing DAQ

Quickstart instructions:

This code is an extension of the OTS-DAQ project and requires it to function. To setup OTS-DAQ use the instructions listed here for installing the core OTS-DAQ packages. This must be done first! Once the OTSDAQ core dependencies are set up, the CMS Timing interface code can be included.

If you are one of the project managers and plan on making modifications to the code, you can checkout the repository doing the following assuming you have valid kerberos credentials,

cd $MRB_SOURCE # this is the 'srcs' directory that will be set in the course of setting up OTS-DAQ
mrb gitCheckout -d otsdaq_cmstiming ssh://

Otherwise, you can just clone the directory using the http sever,

cd $MRB_SOURCE # this is the srcs directory that will be set in the course of setting up OTS-DAQ
mrb gitCheckout -d otsdaq_cmstiming

Alternatively, if you do not have mrb set up, you can check out the code using git directly,

git clone otsdaq_cmstiming 

If you don't checkout using ssh, you will not be able to push your changes to redmine.

Once the package is checked out or if you are starting a new session, source the environment,

source /path/to/products/area/setup # e.g. /data/ups/setup
cd my/mrb/working/directory # this is where localProducts_otsdaq_* and srcs resides
setup mrb
setup git
source local*/setup
source mrbSetEnv


Ideally, everything that is needed for a user to run OTSDAQ will be contained in the otsdaq_cmstiming directory and the code in otsdaq, otsdaq_utilities, and otsdaq_components will not need to be touched. If there is a situation where you wish to modify part of the core code, it is advised to put in a request with one of the maintainers (Lorenzo, Ryan, or Eric).

Below is a summary of some of the parts that will need to be modified in order to set up communication with the experimental device.
