Introduction
Assignement of registers value done in DAQ/Acquisition.cpp, parameters are usually tuned at the start of a MUSIC experiment with the help of CoMPASS software.
Assigned registers saved in --> reg_Board%i.txt
Usage
Digitizer class function --> dig->WriteRegister(Register::#DPP::#PHA::#name, #value_in_hexadecimal, #channel_index)
To access registers values, looked in CoMPASS software (or if saved in reg_Board%i.txt) with register address "Reg" defined by --> 0x####
Aggregate registers --> MaxAggregatePerBlockTransfer //Reg=0xEF1C --> NumberEventsPerAggregate_G //Reg=0x1034
Standard registers defined and assigned in --> boardCommonParameters(Digitizer * dig)
Specific registers per MUSIC experiment defined and assigned in --> boardSetParameters(...) where inputs defined in main function --> double BoardConfigurationval //Reg=0x8000 --> double DPPAlgoCtrl //Reg=0x1080 --> double DPPAlgoCtrl_10A0 //Reg=0x10A0 --> double DPPAlgoCtrl_10AC //Reg=0x10AC --> double ShapedTriggerWidthVal //Reg=0x1084 in steps of 16ns, 96=616 --> double InputSec[7] // Corresponding to CoMPASS Inputs Section 0. Not used 1. //Reg=0x1020 RecordLength input N such length (ns) == N84 2. //Reg=0x1038 PreTrigger in steps of 16ns, input N such length (ns) == N4*4 3. Not used 4. Not used 5. //Reg=0x1098 DCoffset DC% = 1 - input/65535 (ChannelDCOffset) 6. //Reg=0x1028 CoarseGain 0=x1 or 1=x4 (InputDynamicRange) --> double DiscriSec[4] // Corresponding to CoMPASS Discriminator Section 0. //Reg=0x106C TriggerThreshold in lsb 1. //Reg=0x1074 TriggerHoldOffWidth in steps of 16ns 2. //Reg=0x1054 FastDiscriSmooth, e.g. 20=64samp, 63=128samp, (RCCR2SmoothingFactor) 3. //Reg=0x1058 InputRiseTime in steps of 16ns --> double TrapSec[7] // Corresponding to CoMPASS Trapezoid Section 0. //Reg=0x105C RiseTime in steps of 16ns 1. //Reg=0x1060 FlatTop in steps of 16ns 2. //Reg=0x1068 PoleZero in steps of 16ns (DecayTime) 3. //Reg=0x1064 PeakingTime in steps of 16ns 4. Not used 5. //Reg=0x1078 PeakHoldOff in steps of 16ns 6. //Reg=0x10C4 fine gain, eg 1==0x00006C3A (FineGain)
