If you have the OS tick rate at 1 K Hz,
You could set the BO's HIGH field to something .001 - 1 millisecond
set the SCAN rate to .01 Hz

It is unclear what the jitter would be on the scan task - it should be under 100 usecs if you are on vxWorks or RTEMS.
Does jitter matter or just the pulse rate?
How wide of a pulse is required?

It would be interesting to hear your results.

Subject: Pulse Train Record
 
Is it possible to use a bo for a pulse train output?  I have an
application where I need to pulse a chemical metering pump which
requires a pulse train to control it at between 0-100 pulses per second,
and was wondering if I could use a simple digital output bit to do it,
or if I need some device support as well.
