I am trying to dynamically control the delay and pulse width of a retriggerable pulse on a 6602. I have used info from "Generate retriggerable pulse switch cycle.vi" and PWM examples and discussion forum subject "Deterministic updating of retriggerable pulses". If I use the switch cycle, it doesn't work at all. If I just use "program", it works but sometimes my pulse is shortened or missing (I assume this is when the pulse specs are re-written). How can I asynchronously change pulse specs without interrupting the current pulse?
