How CountRestingStates.bs2 Works
CountRestingStates.bs2 is just CountStartPulses.bs2 with a few modifications. The first
change was just the display heading for the information in the Debug Terminal. The
command
CR,
instead of low pulses that only last 2.4 ms. To accommodate for high pulses instead of
low pulses, the command
To search for 20-35 ms durations instead of 2.4 ms durations, the condition for the

THEN
PULSIN 9, 1, time
IF (time > 1000) THEN
ENDIF
. Next, the program has to search for high pulses that last between 20 and 35 ms
