Here we'll describe the user event 137 structure that contains the configuration files used by the ROCs to initialize various modules and settings. These are inserted at Prestart.

Example User Event 137 Structure

c source code in readout list

 size_t maxsize = 3 * 1024 * 1024;
 int nwords = 0, inum=0;

 UEOPEN(137,BT_BANK,0);

 nwords = rocFile2Event("/daqfs/daq_setups/vtp-mpdro/cfg/davtp3.config",
			 (uint8_t *)rol->dabufp,
			 ROCID, inum++, maxsize);
 rol->dabufp += nwords;
 nwords = rocFile2Event("/daqfs/daq_setups/vtp-mpdro/cfg/pedestals/daq_ped_bb_gem_run10975.dat",
			 (uint8_t *)rol->dabufp,
			 ROCID, inum++, maxsize);
 rol->dabufp += nwords;

 UECLOSE;

hex dump
