Digitizer and Improved Monitoring

Samuel Ross Meehan requested to merge digi-with-new-monitoring-features into master

This is a bit of a joint MR with the following :

  • Inclusion of the digitizer receiver module alone with a monitoring module (which will be developed in the future to a greater extent but just put in place to serve as an example
  • Improvement of the base monitoring software from which other monitoring modules inherit
  • This pulls in the latest version of faser-common which has a fix in the Digitizer code to fix a small, but significant, bug in the parsing of the header

This supercedes the MRs : https://gitlab.cern.ch/faser/daq/-/merge_requests/48 and https://gitlab.cern.ch/faser/daq/-/merge_requests/47

All of the suggestions in the Digitizer MR (https://gitlab.cern.ch/faser/daq/-/merge_requests/47) have been incorporated here to the degree that they should still be reviewed and discussed. In particular :

  • In the polling, if there are no events in the buffer then a 1.5 ms pause occurs
  • The sendECR() and runner() use a common mutex to protect against race conditions which would otherwise exist when reading out the digitizer event buffer
