View source for New Delayed Helicity Readout Scheme for Physics Events Trigger

Paul King has this outline for a new scheme to readout the delayed helicity for Physics Events Trigger (instead of using Scalers RingBuffer):

 Running in background:

* '''On Pattern Start:'''
# Increment pattern counter
# Grab reported helicity
# Push onto running seed (30-bit)
# Clear pattern phase counter

* '''On T_Settle Transition:'''
# Increment pattern phase counter
# Increment T_Settle counter


 Then, when a physics event triggers DAQ:

* '''On CODA Event:'''
# Report current seed value
# report current pattern phase
# Report current pattern and T_Settle counters
