You will be using the production readout system to read a "traditional" event segment and scaler bank. Traditional event segments and scaler banks allow you to use existing code for the old readout system.
You must register a traditional event segment and scaler readout by editing Skeleton.cpp:
Locate the function MyExperiment::SetupReadout. It should look like this:
void
CMyExperiment::SetupReadout(CExperiment& rExperiment)
{
CReadoutMain::SetupReadout(rExperiment);
// Insert your code below this comment.
rExperiment.AddEventSegment(new MySegment);
}
Modify the last executable line of this function to read:
... rExperiment.AddEventSegment(new CTraditionalEventSegment);
Locate the function CMyExperiment::SetupScalers and modify it to read:
void
CMyExperiment::SetupScalers(CExperiment& rExperiment)
{
CReadoutMain::SetupScalers(rExperiment);
// Insert your code below this comment.
rExperiment.AddScalerModule(new CTraditionalScalerReadout);
}
In the production readout framework, scalers are counted difrerently. Scalers come in banks, and each scaler bank is expected to supply a count of the number of scalers it reads. To accomodate this, the daq_SetScalerCount function has been removed, and the old skeleton code needs to define and implement a new function named numscl() that returns this information.
In our sample, this means that gasN4_daq.cpp must be edited as follows:
Remove the call to daq_SetScalerCount from iniscl():
Old code:
...
daq\_SetScalerCount(32);
INIT4434(SCALER\_B,SCALER\_C,SCALER\_N);
...
New code:
...
INIT4434(SCALER\_B,SCALER\_C,SCALER\_N);
...
Add the definition and implementation of numscl:
/**
numscl - return the number of scalers to be read:
**/
unsigned int numscl()
{
return 32;
}
Since the production readout system does not manage the CAMAC system the same way, be sure to do a branchinit() and crateinit() on every branch and crate you reference.
