Introduction The Cyton-CXP
CYT-4-2 BitFlow, Inc. Version A.0
For example, let’s say you want a pulse that is example 1.2345678 seconds long. This
is done by programing the TS table with three sub pulse as shown below
Entry 1: 12 * 100 milliseconds = 1.2 seconds
Entry 2: 345 * 100 microseconds = 0.0345 seconds
Entry 3: 678 * 100 nanoseconds = 0.0000678 seconds
When these three entries are “run”, they are output one after the from the TS creating
a single pulse of the desired length:
1.2 + 0.0345 + 0.0000678 = 1.2345678
As you can see, this system provides both a wide range of durations as well as very
accurate durations.
Pulse can be either high or low (0 or 1). By programming both high pulses and low
pulses any pulse train can be created.
Chaining Pulses
Pulses are chained together link a linked list. Each pulse entry have a “next” field
which tells the system where in the table the next pulse should come from. This facility
is used to build up complex sequences as well as looping sequences.
Triggering
Each entry in the TS table can produce one pulse. Each entry has a “condition” under
which it will get executed. The conditions can be immediate, in other words, as soon
as the TS gets to this entry it immediately produces the programmed pules. Or it can
be programmed to wait for a trigger. Various trigger conditions are supported.
By adding this condition, the pulse train produced can be run in “one-shot” mode,
where one trigger produces one pulse.
