# NOTES:
# GeigerLog supports Gamma-Scout models Standard, Alert, Rechargeable, and Online.
# Since Standard, Alert, and Rechargeable do not support logging from these devices,
# GeigerLog implements their use for logging such that those GS counters return
# only empty values (= NAN values) as logged data.
# The Online Gamma-Scout .... tbd
# Logging requires that a connection exists to a GS device, even if only as a
# simulator, see next.
# SIMULATION:
# If a GS device is not available, it can be simulated. To do so start program
# GLgammascoutsim.py in a separate Terminal window as SUDO (!):
# sudo gtools/GLgammascoutsim.py
# and start GeigerLog with the command gstesting, like:
# python3 geigerlog gstesting
# GS will be connectable and allows downloading from the simulated device (but
# logging will result in empty values only).

# The contents of the protocol memory consists of either 2 byte pulse entries or
# special codes. It must be interpreted byte by byte. Special codes start with a
# byte with its high-nibble being 0xF. If the high-nibble is not 0xF, this byte
# will be the first byte of a 2 byte pulse entry.
# This 2 byte pulse entry represents the number of pulses collected during the
# last protocol interval (or the number of pulse during an out-of-band protocol
# interval, see below). The highest 5 bits contain the exponent, the lower 11
# bits the mantissa. E.g.:
# 0x3E27 = %0011111000100111 = 2^7 (exponent) * 1575 (mantissa) = 201600
