Control Signal Conditioning

Hello all,


I would like to be able to have a contol signal that drives a slewing mux to have an immediate turn on time and a minimum 10sec delay before being allowed to turn off. In other words, a peak and hold on the control signal that's longer than the 2 sec max on the various rms and peaking limiters. I believe there is a way to accomplish this with SigmaStudio primitives like a resettable One-shot and a timer/counter. I have tried various combinations and am not having much luck. Here are my questions:


1. Has somebody done this before and is willing to share their circuit with me?


2. Is it possible to exceed the 2sec limit built into the primitives by sending larger values from my micro?


3. Is there library of circuit blocks someplace, a sort of repository, where people have shared various SigmaStudio solutions to their design issues, or do most folks keep their "inventions" close to the vest?
