Introduction

This repository is providing scripts necessary for communication of pyBAR with the DAQ (dispatcher, run control) of the SHiP Charm experiment. Hit data from FE-I4 modules (provided by pyBAR) is converted to SHiP data format and sent to DAQ. Also run_control commands are recieved and executed.

Installation

You have to have Python 2/3 with the following modules installed:

• cython
• tables
• numba
• numpy
• zmq

You also have to have installed ControlHost in the same folder as the top project folder, and compiled a dynamic library libconthost.so. Also required are pixel_clusterizer, pyBAR and pybar_fei4_interpreter

The installation procedure for ControlHost is as follows:

• Download and untar archive to emtpy directory, e.g. "ControlHost". Go to this directory:

cd ControlHost/src/

• add the following lines to Makefile.project:

include $(VPATH)/Options.Makefile  # after the first non-commented statement

CFLAGS_COMMON := -fPIC $(CFLAGS_COMMON)
CXXFLAGS_COMMON := -fPIC $(CXXFLAGS_COMMON)

• build the project:

make

• copy the static libary "libconthost.a" to an temporary empty directory
• in this directory perform the following commands one by one

ar -x libconthost.a
gcc -shared *.o -o libconthost_shared.so
rm -f *.o

• copy conthost_shared.so to the "ControlHost" folder.
• check the presence of the system binary files dispatch, dispstat, stopdisp and the application executables tst1, tstsnd, tstrcv:

cd ../bin; ls -l

If you are new to Python please look at the installation guide in the wiki. Since it is recommended to change example files according to your needs you should install the module with

python setup.py develop
